Cycling Refrigerated air dryer or VSD compressor air dryer

Reference: G.2.1

LEME Mitigation

Replace air dryer by high efficiency equipment

For industrial uses requiring an medium dry air (dew compressed air: 3°C)

specific consumption ≤ 5 kWh/1000 m3 (air cooled) ≤ 3 kWh/1000 m3 (water cooled) HFC refrigerants only

EU IPPC /BAT/EE ISO 8573-1:2010

Estimated pay back time short term : 2-4 years, medium term: 4-6 years, long term : 6-8 years (*)

Medium term

Considering the average humidity of the ambient air of Mauritius, drying of compressed air is necessary to protect the devices of condensations, such as pneumatic motors or control valves . Only drying condensation by cold systems allows high flows of air.
