I. Refrigeration and air conditioning applications:
_water / glycol cooling;
_ free cooling;
II. Industrial applications:
_ cooling of water or other different liquids;
_ food, power, processand general industry;
Heat Exchanger:
Optimized "V type"design provideslarge capacity with compact size. Innovative heat exchanger design givesexcellent design gives excellent heat transfer with minimized refrigerantcharge, thanks to the new fins corrugation, developed by Tech Free, combinedwith two different tube sizes 3/8" and 5/8". In the standard execution, heatexchanger manufactured from copper tubes and aluminum fins. Double connectionprovides opportunity for two completely independent heat exchangers. Each heatexchanger undergoes a pressure and leaking test with dry air at 10 bar.

Fan motor:
Three different fan diameter available: 800, 910 and1000mm with three-phase motor 380V-50Hz. The motors are with external rotor,made in accordance with IP54. Each fan chamber is separated by internal baffleplates which enables optimal capacity control by separate running of the fans.

Frame and casework:
Casework made with galvanized steel sheetspainted (corrosion resistance) with epoxy finish. New design frame provides highrigidity also for heavy applications. New system perfectly protests the heatexchanger tubes during transportation and operation against vibration andthermal expansion. Support manufactured in galvanized steel.
