COOLTECH is a Finland manufacturer of the refrigeration compressor units based on open-type and semi-hermetic screw and piston compressors operating with freon, ammonia, propane, ethylene, isobutane, propylene, carbon dioxide and etc.
COOLTECH supplies compressor units based on 1 compressor (series CTX SL/ CTW SL) as well as 2 compressors (CTX DUO / CTW DUO).
Compressor unit series DUO PACK is based on two screw compressors ensuring higher reliability due to the use of one oil separator, economiser, oil pump, filter and oil cooler mounted on a single skid. These units are widely used where it is necessary to optimize criterion “cost — efficiency — dimensions”.
By the using of system with frequency converter, COOLTECH compressor units allow to save up to 18% of electric energy at partial load mods.
The expected service life of COOLTECH compressor units is 20 years and more.
