Design Temp -29oC to +204oC
Electric Connection 3 ph 380/440 volt
Used for cooling CNG inter-stage & discharge gas for a 3-stage 74 to 94 kW compressor package. Incorporates oil cooler.
No-maintenance rugged API oil field type cooler optimized for fan energy consumption & tube area while providing most efficient compression energy consumption, knockout of oil & condensates & lowest discharge gas temperature. Discharge air between 70C & 100C above inlet air. Discharge gas < 40C above discharge air temperature.

Experienced operators of water cooled systems know loss of efficiency over time due to corrosion & fouling of all water passages. Water systems demand expensive ongoing water treatment, daily evaporation of up to 20% of water capacity, & provide an ideal breeding ground for bacteria etc. Use of cooling towers in high humidity conditions severely reduces efficiency. Fan powered by independent motor allows complete evacuation of compressor room air prior to startup of compressor.
