A water-cooled aftercooler reduces the temperature of compressed air after it leaves the compressor. Cooling lowers the air temperature and helps remove moisture that can condense from the compressed air stream.
A water-cooled aftercooler for compressed air uses a compact heat-exchanger construction with compact design. Units can be built to applicable international design codes including TEMA-C, ASME and IS-2825, and pneumatically and hydrostatically tested before dispatch.
The standard parameters include a maximum water inlet temperature range of 32-38 °C, water outlet temperature range of 38-44 °C, water inlet pressure of 3–4 kg/cm²(g), and air inlet pressure of 7–16 kg/cm²(g). The standard air inlet temperature is 60-65 °C, with the air outlet temperature reduced to approximately 40°C or slightly lower.
Delair offers 15 standard models covering 50 m³/hr to 6000 m³/hr, with higher capacities available on request. An auto drain valve can be supplied as an option to remove condensate collected during cooling.
Delair’s AC Series uses about 1 LPM of water for every 10 m³/hr of air, from 5 LPM (AC-50) to 600 LPM (AC-6000).
A water-cooled unit needs a cooling water supply, while an air-cooled unit uses a fan and ambient air.
