ระบบระบายความร้อนแบบแห้ง (TFDC-0103 B)

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

Fan motor:
Three different fan diameter available:800, 910 and 1000mm with three-phase motor 380V-50Hz.The motors are with external rotor, made in accordance with IP54.Each fan chamber is separated by internal baffle plates which enables optimal capacity control by separate running of the fans.

Frame and casework:
Casework made with galvanized steel sheets painted (corrosion resistance) with epoxy finish.New design frame provides high rigidity also for heavy applications.New system perfectly protests the heat exchanger tubes during transportation and operation against vibration and thermal expansion.Support manufactured in galvanized steel.
