ELGi driers and drains
The hot high pressure refrigerant enters into the condenser in gaseous state and gets cooled through the forced circulation of cold air using a fan and flows to the expansion valve in a liquid state.
This granular desiccant bed in the first tower absorbs moisture from the air. The second tower takes the dry purge air from the outlet of tower one and feeds it through a purge valve to regenerate the granular desiccant bed.
As a default, all HLD models above 5X are provided with a Dew Point Stretch Cycle and Purge Optimizer.
Why do I need a drain valve for my air compressor?
Compressed air condenses moisture in dryers, after-coolers and air receivers. This condensate needs to be removed frequently. This process is done by the drain valves.
In ordinary drains, there is always loss of compressed air. Most of the condensate drains have a 4 mm orifice. This 4 mm orifice bleeds about 34 cfm, which is the equivalent of 6.5 kw of power.
ELGi Airmate drains work on the principle of zero air loss and do not bleed your compressed air, consequently saving energy.
