Product Description

Dry Cooler Features:

1. High efficiency heat exchanger: capacity designs for maximizing the heat transfer relative to the energy consumption of the fan. Tube and tube coupling design for low pressure drop in the coil on the media sides(maximum 100KPa at water designing condition). Our thermodynamic and aerodynamic designing software is long year tested and proved in Germany

 

1. Fan: only choose low specific energy consumption fans. Fan nozzle designs for maximum air flow and air throw.Our fans from the world`s leading manufacturer are practically proved to be reliable in operation and long lasting. Motor: protection class IP 54 and insulation class F. Air separator for each fan.

 

1. We facilitate you to have a long lasting and low maintainance operation. Durable material and rigid enclosure with hard gloss powder coated finish. Protective enclosure for both manifolds and U-bends. Unit design for outdoor installation. 100% leakage tested at 31bar.

Common fault and treatment:

number	Observation	Possible cause	Action
1	Fan not turning, noise or vibration when started	Lack of phase or fan impeller blocked	Eliminate blockage
2	Overheating	Air inlet blocked or obstructed by foreign objects, impeller severely deformed or damaged, power supply voltage or frequency not according to requirements, lack of phase, stator and rotor friction	Remove foreign objects, replace impeller, replace motor matching user voltage and frequency, replace fuse and faulty motor components
3	Current too high	Bearings worn, impeller and duct friction, impeller blocked, lack of phase, other obstruction	Replace bearings, adjust the gap between impeller and ducting,  repair circuits, defrosting
4	excessive noise or vibration	Impeller damaged, loose stand, grill damaged, airflow obstruction	Replacement of impeller, tighten loose parts. Repair and replace grill, defrost.
5	Leakage, low insulation resistance	Motor storage influent. Moisture	Dry motor before use.
