Refrigerated Air Dryer RSLF & RSLS Series
August Refrigeration Air Dryer
Compressed air is a reliable and widely source of energy
used in large majority industrial processes. However, the compressor draws in
atmospheric air which is contaminated with dirt, germs, bacteria, water vapour
and unburnt hydrocarbon. Water vapor in the compressed air causes many quality
problems such as premature wear and failure in pneumatic equipment, spoiled
products, damaged system, corrosion of pipe. All these problems could cause
high maintenance costs and air leakage.
For general purposes application, refrigeration dryer
provides the economical and popular method of removing unwanted moisture from
the compressed air. August high efficiency and energy saving refrigeration
dryer provide air quality to ISO8573.1 Classes 4,5 and 6 for water vapour.
Benefits
· Provide air quality to ISO8573.1 (Class 4 to 6 for water vapour)
· Constant dew point with different load conditions
· Low ownership cost
· Low running cost and energy efficiency
· Suitable for all type of air compressor
· Low pressure drops across refrigeration dryer
· Low environment impact as RSLF/RSLS dryeruses only environmentally friendly refrigerant R407c and R134a.
· Simplified maintenance and easy to use
· High reliability
Key Features
· Easy to install, maintain and compact design. RSLF/RSLS dryer has been designed with easy installation with PLUG & PLAY concept. Panels are easily removable and user can have easy access to the refrigerant components for maintenance and cleaning.
· High quality aluminium material uses for condensate drain pipe system, demister housing and inlet/ outlet pipe which reduces the chances of pipe contamination.
· Energy efficient refrigerant compressor. High efficiency refrigerant scroll compressor is used for RSLF/RSLS -200 and above. Better tolerance against liquid damage and less vibration.
· Equipped with mechanical float drain for RSLF-06 to RSLF-40. RSLF-60/RSLS-120 and above equipped with robust and reliable electrical timed drain with option for zero loss electronic drain.
· PCB temperature display for RSLF/RSLS and above with option of PLC control for RSLF/RSLS -120 and above.
Heat Exchanger
High efficiency reinforced aluminum heat exchanger is used
for RSLF-60/RSLS-120 and above allows the refrigerant circuit to be 30% smaller
than traditional refrigeration system and less energy consumption.
1. Air to Air Heat Exchanger
There are two phases (Pre-cool / Re¬heat) in the air to air
heat exchanger. The inlet air is pre-cooled by the outlet cold air whereby heat
is being transfer to cold air. It reduce the energy consumption required by the
refrigerant as portion of the heat load has been removed. At the same time by
re-heating the cold air before it was supply to the production, it reduces the
possibility of condensation at the external surface of the dryer outlet pipe.
2. Air to Refrigerant Heat Exchanger
The pre-cooled air will be further cool to the required dew
point by transferring heat to the cold refrigerant in the air to refrigerant
heat exchanger. The cold air will then be directed to the high efficiency
moisture separator.
The pre-cooled air will be further cool to the required dew
point by transferring heat to the cold refrigerant in the air to refrigerant
heat exchanger. The cold air will then be directed to the high efficiency
moisture separator.
3. High Efficiency Moisture Separator
The cold air passed through the high efficiency moisture
separator and condensate will be removed from the compressed air before being
supply to production.
Stainless Steel Plated Heat Exchanger
Stainless steel plated heat exchanger is used for RSLF-06 to
RSLF-40 and high-pressure RSLF-HP.
