Dry All has been perfecting the art of developing a full range
of HVAC&R line products since 1990. Now Dry All introduces
three more products with cutting-edge technology.
Looking back at the 1990s, Dry All’s range of HVAC&R line
products i.e. Filter Driers, Receivers, Oil Separators,
Accumulators was a humble beginning to its quest for
excellence. Over the years, HVAC&R technology and customers’
needs have gone through a big change. This continues to
challenge the company to upgrade the products and technologies
The Engineers at Dry All acknowledged the need of consumers
and developed new products designed to detect leaks, provide
highly efficient oil separation and highly efficient thermal exchange
design in HVAC&R System. The year 2019 saw the introduction
of following new products from Dry All:
Filter Driers with Fluorescent Dye
Oil Separators with Demister Pad
Brazed Plate Heat Exchangers
Filter Drier with Fluorescent Dye
‘Dry All’ is a leading manufacturer of Filter Driers in India. The
nuanced understanding about HVAC&R system has helped the
company to engineer new Filter Drier that will not only provide
filtration, adsorb moisture and acid but will also help to detect the exact source of a leak in a HVCA&R system.
Tracer Wafer (TW) (manufactured by Spectroline – USA)
charged with a fluorescent dye is placed along with the desiccant.
When the system starts and the TW comes in contact with
refrigerant and oil, the dye in wafer is released and circulates with
the refrigerant. In case of a leak, dye escapes leaving a mark at
the point of the leak. The exact point of a leak is easily visible
under a UV light through yellow glasses. This dye is compatible
with all refrigerants and oil. The dye has also been approved by all
leading compressor and component manufacturers.
Oil Separator with Demister Pad
The role of oil separator is to separate oil from refrigerant in
the discharge line and maintain oil level in the compressor to
prevent system breakdown. This eventually increases the life of
the compressor. The efficiency of conventional oil separator is
approximately 75 per cent and with the introduction of demister
pad, the efficiency of oil separators with demister pad can go up
to 99 per cent.
‘Dry All’ high-efficiency UL certified ‘Oil Separators with
Demister Pad’ is specially designed with SS Wire Mesh. Demister
Pad is capable of capturing even smallest oil molecules and
separate it from refrigerant. These separated oil molecules collide
and forms larger drops. Due to gravity, these larger heavier oil
drops fall at the bottom of the oil separator vessel. Float ball
mechanism helps the oil return to compressor crankcase through
oil return port.
These oil separators minimise the noise and pulsation at the
discharge side. This has a very wide application in VRF systems.
Brazed Plate Heat Exchanger
‘Dry All’ introduced Brazed Plate Heat Exchangers (BPHE) in
collaboration with ‘Kaori’. BPHEs can be used both on evaporator
and condenser side in chiller and heat pump respectively. BPHEs
are designed to offer the following advantages:
Highly efficient thermal design – high performance
More efficient use of materials – cost effective
Mass reduction in size–compact, less space, less weight
Proven and reliable quality – long lifetime durability
These are the trailblazer in the realm of the HVAC&R industry.
