5 Common Mistakes You can make while you Install a Filter Drier!

Introduction

Dry All as a leading manufacturer of Full Range of HVAC&R Line Products is constantly innovating, developing and, designing products to meet the requirements of the industry.

Since its inception, Dry All stakeholders with their most efficient design and R&D Team has always emphasized on producing the latest technology products to meet the challenges of the constantly evolving technology in the HVAC&R industry.

Dry All “5 Common Mistakes” series is designed to help the installer/ technician to avoid common mistakes that one can make during product installation.

The second in the series is on Filter Drier. Here are five common mistakes you can make while Installing a Filter Drier. 

1)   Installing the Filter Drier in wrong direction

Mistake – Installing a Filter Drier in the wrong direction is a complete no-no. All Liquid Line and Suction Line Filter Driers are designed as Uni-Flow except Bi-Flow Filter Driers. Normal HVAC&R cycle moves in one direction and filter driers are designed to be used in one direction only. The inlet of the filter drier has a spring that cushion the desiccant from attrition. The inlet also has filtration media to capture all contamination. This is followed by a desiccant bed comprising of Molecular Sieves and Activated Alumina. The outlet again has final filtration media to filter contamination up to 20 microns.

Consequences– If the technician makes the mistake of installing the drier in the wrong direction, the drier will not work and serve the purpose for which it has been designed. So, no filtration of contamination and no drying of moisture. There can be other problems like pressure drops, contamination escaping the drier, and so on.

Solution– The label of the drier indicates the flow direction and the technician have to be careful to follow the same.

2)   Choosing the wrong model/size of Drier

Mistake – Line size cannot be the only criteria for selecting a drier. For example, if the line size is 3/8”, driers available for the same size are 033, 053, 083, 163 & 303. Technician sometimes to save cost can choose a smaller drier and sometimes in a zeal to clean chooses an over-size drier.

Consequences – A small drier will not serve the purpose for it has been installed. Therefore, no proper filtration and no drying. If oversized, there will be a pressure drop and the system will not work properly.

Solution– Choosing the right size of drier is of utmost importance. The technician can consult the technical catalogue provided by the manufacturer and do his trials and finalize the right size. Dry All provides all technical support to its customer to choose the right model.

3) Brazing Installation Mistake

Mistake – There are many mistakes a technician can make while brazing a filter drier to the system. The most common mistakes are not protecting the connection and the drier joint and secondly not bleeding positive nitrogen pressure.        

Consequences– a) If the joint of the drier body with a connector is not protected with a wet rag or protective clay available these days, the paint at the joint will burn off. This will become a weak area and will start rusting. In some extreme cases, due to excessive heating, this joint may also leak. b) If you miss out to bleed oxygen while brazing, scaling, and oxidation will occur inside the system tubing.

Solution – a) Always cover the Filter Drier with wet rage or protection clay before brazing. B) Bleed nitrogen through the drier during brazing. 

4)   Threaded joint installation

Mistake – Not using the right torque for the installation of Filter Driers with threaded joints.

Consequences- Using the right torque is very important to install a threaded joint Filter Drier. If the torque is less, it will result in a leak. If extra torque is applied, it may break the nut or damage the thread.

Solution – You are required to follow the instructions prescribed by the manufacturer for the threaded joint.  

5)   Avoiding Sight Glass / Liquid Indicator / Moisture Indicator

Mistake – A small window is installed immediately after the liquid line filter drier. This window is called a Sight Glass / Liquid Indicator / Moisture Indicator. The glass window allows the technician to sight the moving refrigerant in liquid form. It is also called a moisture indicator as it has a special paper that changes color based on moisture present in the system and hence also indicates the amount of moisture present in the system. One of the common mistakes is not installing a Sight Glass / Liquid Indicator / Moisture Indicator on the liquid line immediately after the liquid line filter drier. Technician skips installing Sight Glass / Liquid Indicator / Moisture Indicator to avoid an additional cost or sometimes he thinks it’s just not necessary.

Consequences– A periodic check of the HVAC&R System is required and this includes checking the condition of the filter drier and the best indicator of the health of the liquid line filter drier is through the Liquid Indicator. In absence of the same, the technician has to rely on conventional and technical wrong methods to decide on a change of filter drier.

Solution –Always install a Liquid Indicator with good quality moisture indicator immediately after the sight glass. One more solution to this mistake is installing a filter drier with inbuilt liquid indicator/sight glass at the outlet of the filter drier. This helps in saving space, reduce joints, and save money.

5 Common Mistakes You can make while you Install an Oil Separator!

Introduction

Dry All as a leading manufacturer of Full Range of HVAC&R Line Products is constantly innovating, developing and designing products to meet the requirements of the industry.

Since its inception, Dry All stakeholders with their most efficient design and R&D team has always emphasized on producing the latest technology products to meet the challenges of the constantly evolving technology in the HVAC&R industry.

Dry All “5 Common Mistakes” series is designed to help the installer / technician to avoid most common mistakes that one can make during product installation.

The first series is on Oil Separator. Here are five common mistakes you can make while Installing an Oil Separator.  

1)   No Pre-charging of Oil in the Oil separator

Mistake – Float ball type Oil Separators come with instruction on the quantity of oil to be charged before installation. It is observed that technician miss out this instruction because of negligence and sometimes because of a lack of understanding on why this is required. This pre-charge is required to bring the oil separator mechanism to activation level. Oil Separator manufacturer cannot give you the same pre-charged because the oil has to be exactly the same grade as the compressor oil.

Consequences– If the Oil separator is not pre-charged with oil quantity as prescribed by the manufacturer, then the oil coming out of the compressors gets accumulated in the oil separator up to the activation amount of the float ball mechanism; this may result in the failure of compressor due to starvation of Oil

Solution-All Oil separators with float ball mechanism have to be pre-charged with the amount of Oil prescribed by the manufacturer. A little more oil than the amount required for the activation of the float, ball mechanism helps the oil coming out of the compressor to return back quickly to the compressor.

2)   Opening of the NPT port

Mistake – Oil Separators are provided with NPT port, closed with a dead nut. The NPT port is provided for installation of pressure relive device as may be required by the system design. Common mistake observed is that the technician opens and uses this port for charging of oil.

Consequences – In the manufacturing process the NPT port is closed with the help of a dead nut using a special quality sealant. It is strongly recommended that the dead nut from the port has to be opened only and only for installation of pressure relief device. If the dead nut is opened for charging of oil, the opening process destroys the sealant used. In addition, after the oil charge when the dead nut is installed back, the previous tightening torque may not be achieved. This creates a leak at the NPT port immediately or over a period of time.

Solution- The NPT port should be opened for only attachment of the PRV or any other pressure relief device and not for oil charging or any other purpose. In case the port is used for installation of any other device, the technician has to make sure that there is no leakage from this point.

3)   Closing of the Oil Return line

Mistake – Smaller size of oil return line or blockage of oil return line.

Consequences-Due to the small size or blockage of the oil return line the oil is unable to travel back to the suction line and to the compressor. This creates a tremendous hydraulic pressure on the ball of the float ball mechanism and eventually the ball gets pinched resulting in the failure of the Oil Separator

Solution – Install adequate oil return line size according to the system design to insure travel back of the oil to the compressor. Use of an oil strainer on the line is strongly recommended to filter the oil and prevent such blockage. 

4)   Oil Charging Procedure

Mistake – Not pre-charging of the oil into the Oil Separator before start of installation.

Consequences– The most common mistake noticed is pre-charging of oil through the outlet of the oil separator after the inlet tube has been brazed. If oil is charged after one joint is brazed it gets tough to pour the oil through another port due to the air pressure. Also, the oil cannot be charged through the NPT port as explained above.

Solution – Remove the Oil separator from packing. Remove inlet and outlet rubber plugs. The Dry All Oil Separators are pre-charged with positive nitrogen. Allow the same to escape completely. Pre charge from inlet keeping the outlet port open. Now braze the oil separator to the system. Make sure to use wet rag so that the brazing heat is not transferred to the Oil Separator joints or body.   

5)   Charging of wrong grade of Oil

Mistake – Not charging the right grade of oil or the oil of the grade and type different from the Compressors.

Consequences– The compressor needs the lubrications as it contains moving parts. The lubricating oil for the compressor is designed with respect to the different parameters such as refrigerant, temperature, viscosity etc. Due to the mismatch of the grade or type of the oil in the oil separator and compressors the lubrication gets affected and in over a period of time compressor fails

Solution –Check the data sheet of the compressor manufacturer and identify the oil and its grade. Pre charge the Oil Separator with same grade of oil as the data sheet

‘Dry All’ Suction Filters

From the expert in HVAC&R filter drier innovation & technology.

Introduction

Moisture and contamination are an inherent problem of a HVAC&R system and one of the biggest challenges that any technician faces during installation and servicing of the units.

While most of these problems in liquid line and discharge line are taken care of by the ‘Liquid Line Filter Drier’, some moisture and contamination can remain unchecked in condenser and suction line and can pass into  the compressor – the heart of the system.

Protection may be required to field build contamination during installation where cutting or brazing of lines was done.

Additional protection will also be required for system clean-up after a burnout or when major work has been performed on the system.

System may also face problem of fluorinated refrigerant after a compressor motor burn out.

Solution

To take care of all these issues, one needs to install a Filter on to the Suction Line to catch on the contamination and moisture. The choices available are:

  1. Dry All DCHSF Series – Suction Line Filter Drier (With Solid Core Desiccant)
  2. Dry All DSF Series – Suction Line Filter (With Filter)

In this article we will primarily talk about the Suction Line Filter which is one of the effective solutions to take care of these problems.

Making a Choice

Normally a Liquid Line Filter Drier can take care of the contamination and moisture in the system. An additional precaution by way of installing a Filter Drier on suction line would always help. The pressure in suction line is already low. Installation of a Filter Drier will take care of contamination and moisture but this may result in further pressure drop in the suction line.

The alternate and the best solution to the same is a Suction Line Filter Drier. Yes, a Suction Line Filter and NOT Suction Line Filter Drier.

Dry All DSF Suction Line Filterseries is used in the suction line of a HVAC&R System, for the purpose of removing and retaining solid contaminants from the refrigerant with lowest pressure drop.

The filter media used in Dry All Suction Line Filters makes a High Full Flow Design which provides large filtration area with in-depth cleaning but with lowest pressure drop. Inserted Micro Glass Filter Paper and Plated Steel Frame insures lubricant compatibility.  The flow velocity of the Suction Filter does not act as Oil Trap and hence proper oil return is obtained.

Schrader Valves are provided on both the inlet and outlet of the Suction Filter. This is to permit pressure drop readings during clean-up. The inlet schrader valve can also be used for charging of refrigerant to take care of contaminants in the refrigerant if any.

Construction of ‘Suction Line Filter’.

Dry All Suction Line Filter looks like any other Filter Drier. The difference is the internal construction. The general filtration media and desiccant is replaced with a specially designed pleated filter in a plated steel case.

The pleated filter assembly is made of Inserted ‘Micro Glass Filter Paper’ and placed in specially designed ‘Plated Steel Frame’ to support the paper. The dirt is imbedded in the fibres of the element. If additional dirt enters the Suction Filter, it will be caught in the dead pocket of the element by the change in direction of the refrigerant flow.

Major Application

1.VRV / VRF Air conditioning Units
2.Large Air-condition or Cooling Systems
3.Transport Refrigeration
4.Bus Air conditioning
5.Chillers

Models Available

Currently Dry All Suction Filters are available in 16, 41 & 75 Series.Connections available are 3/8”, 1/2”, 5/8”, 3/4”, 7/8”, 1-1/8”, 1-3/8”, 1-5/8”.

For Larger Capacity Systems:

Where the DSF Series of Suction Filter are small in capacity, we recommend the use of Dry All DRC Series of Core Shell – Replaceable Drier Shell and Dry All Replaceable Core DA-48 / DC-48 / DB-48 & Filters DPE-48BD as required.

The pressure drop through the temporarily installed cores will be higher as compared to the filter. After clean-up, the use of filter elements will assure a minimum pressure drop when the system is in normal operation.

Following steps can be followed:

  1. Clean all solid contaminants with Dry All DSS-48. After clean up, remove and store for future use.
  2. Replace with solid core Dry All DA-48 / DC-48 / DB-48 which will take care of all contamination, moisture and burnout issues.
  3. In-case of pressure drop issue with solid core, replace with Dry All DPE48BD for continued protection with minimum pressure drop.

Since its inception, Dry All stakeholders including the owners, design and R&D team have always emphasized on producing the latest technology products at competitive prices.

A liquid Refrigerant Receiver is a pressure vessel designed to hold liquid refrigerant in a refrigeration system. It collects the condensed liquid refrigerant leaving from the condenser outlet and feeds it in liquid form to the liquid line of the refrigeration system. Dry All offers widest range of Liquid Refrigerant Receivers.  

Dry All Liquid Refrigerant Receivers

Liquid Line Receiver’s internal volume allows it to store liquid refrigerant and hence allow the refrigeration system to respond to varying heat loads by varying the refrigerant flow rate. For this a thermostatic expansion valve is used in combination with a receiver. It also ensures that only liquid refrigerant is fed to the liquid line of the refrigeration system.

If sized correctly, the liquid refrigerant receiver can also be used for pump down repair of the refrigeration system, storing the liquid refrigerant in the receiver provided. Provision of liquid refrigerant receivers is always desired to allow a system to be serviced or repaired with ease and without losing the refrigerant.

Indian HVAC&R Industry in Corona Virus Crisis

Converting Challenges into Opportunity

While the world goes through this crisis collectively, I wonder in my ubiquitous thoughts if this is really a crisis or a boon in disguise.

Can one really guess what the future holds after all this gets over and we get back to so-called normal life? Would the normal life be as fast-paced, busy, crowded as before or we have learnt our lessons and ‘Social Distancing’ will be the way of life?

As Indians, would we take up ‘Namaste’ and ‘Pranam’ as the way of greeting instead of handshake and hugs? Will we start standing in the queue with a decent gap? Will we have a small gathering at weddings and religious functions? Would our cities be cleaner? Would our cities learn from the examples of Surat (1994) and Thane (1998) and follow the same path of rebuilding amazing cities out of trash? Will the politicians rise above the game of playing the excluding politics of appeasing only to the minority and poor and totally ignoring the rules of the game? Or maybe we will get back to the organised chaos that we had in India before Covid19 happened to us. I am sure no expert will be able to predict this and it will continue to be a game of guesses and opinions.

But things will surely change and so will our HVAC&R Industry. For all of us, so-called the summer season of 2020 for domestic Air-conditioners is lost. These sales cannot be replaced as India’s weather condition has a marked summer and this definitely sees a spike in sales in the month of April & May. With the lockdown throughout April and now extended till 03rd May, we have already lost the business of April 2020. We still have the peak hot month of May in hand to probably cover some of the sales. Even though sales may happen but installation may be a challenge as the workers involved in installation may have moved to their home towns and villages by this time. Another challenge in this segment could be the availability of funds with the middle-class who constitutes to be a major buyer for home air-conditioners. To this segment of customers, purchasing of air-conditioners is still considered a luxury but a necessity.

On the commercial front things may take a positive turn. Infrastructure development will take place and this will boost up the HVAC&R Industry. With the losses suffered in the stock market, people will look into new areas of investment and that would probably be real estate. This will further boost up the economy. The slum pockets are the most challenging and difficult areas to control diseases like Corona. Probably Government will now realise how important it is to remove slums ( only 1 bathroom for 140 people) and offer proper housing to people where hygiene can be taken care of.

In this development phase Hospital and Medical facilities would also be an important part of this infrastructure development. All these would require ventilation, air-conditioning and refrigeration. There is no choice for India but to improve this infrastructure to support the medical needs of its citizens and bring it at par with international standards, Drug manufacturing companies, Hospitals, Nursing homes, Testing Labs, Blood Banks, Medical Equipment manufacturing companies etc would all demand HVAC&R. India Government has sanctioned Rs.15000 Crore Package to Boost Health Infrastructure until March 2024. Out of this 7774 Crore will be released immediately. India with its talent pool will also become a Global Bio-Medical hub for the world. This would open up a huge opportunity for the HVAC&R Industry.

We had been talking about cold chain development in India for some time but it never took off as anticipated. Inadequate cold-chain infrastructure has hampered India’s Cold Chain Industry. In spite of all the challenges the Indian cold chain market reached a value of INR 1,288 Billion in 2019. The market is further projected to reach INR 2,918 Billion by 2025, growing at a CAGR of 14.6% during 2020-2025. The Pandemic may affect the Cold Chain growth, however, we still have chances of this segment of the industry booming and what better time than this when we realise how important it is to build up this segment to be prepared for the unexpected and unpredictable future.

India, a country that has always been considered a good manufacturing base besides its’ infrastructure and bureaucracy, will now become a great alternative. With the disturbing supply chain worldwide because of Corona Virus, the business will shift to the Mighty 5 (India, Indonesia, Malaysia, Thailand and Vietnam). India will be surely looked upon as a good manufacturing base. It was always considered so but minus it infrastructure and bureaucracy. But in today’s scenario, with the proactive current Government, international business community may still consider to ignore these few shortcomings and consider India as an investment destination for manufacturing. Japan is offering 215 million to companies planning to shift from China to other countries. The USA was already doing so because of the trade war and with this epidemic, it will be much earlier and faster than anticipated.

With Indian Rupee at its weakest level against the US Dollar, it is time for business in India to look at ‘Make in India’ as best alternate to imports. We have the expertise, knowledge pool and a ready domestic and international market to start manufacturing of all HVAC&R Parts in India and reduce dependence on imports as much as possible. There has to be a beginning and let it be now.

Every dark cloud has a silver lining and it is up to us to look at that silver lining. This is the time to re-think, re-strategize, re-organise, re-plan and do things the new way. Why only Government, but Corporates and Private Sector should also follow this line for their business A.C.(After Corona). It is for sure that post-COVID-19 this world of ours is going to be different, but it is in our hands to make sure that it looks different towards a better tomorrow. 

We should constantly re frame our understanding of what’s happening because no one knows what’s happening and what the future has in store. Till things get back to normal, Stay Home and Stay Safe.
