Product Description


An air cooled chiller is a machine that removes heat from a liquid via a vapor-compression cycle. Air cooled chillers are directly cooled by ambient air being mechanically circulated directly through the machine's condenser coil to expel heat to the atmosphere. 


The two types of air cooled chillers are scroll compressor air cooled chillers and screw compressor air cooled chillers. Scroll compressors are used for the smaller air cooled chillers, and screw compressors are used for larger air cooled chillers and have a variable speed drive option for increased efficiency. Click here to learn more about the difference between Air Cooled Scroll Chiller and water cooled chiller.



Features:


1. Scroll compressor for modle 12-180kw, semi-hermetic screw compressor for modle 130-2300kw. Each compressor is equipped with a crankcase heater and a thermal overload cut-out; the screw compressor is also complete with a built-in electronic protection with temperature sensor located directly in the motor winding and on the discharge line.

2. External rotor type axial fans, equipped with three phase direct drive motors, low noise 8 poles, protection level IP54, provided with a protective outlet grille.

Evaporator built with high efficiency shell and tube type heat exchanger, factory insulated with flexible close cell material.

3. Condenser built with seamless copper tubes mechanically expanded into blue hydrophilic aluminum fins.

4. Refrigerant circuit complete with charge valves, filter drier, sight glass, gas-liquid separator, thermostatic expansion valve, high & low pressure switch. The heat pump unit is completed also with 4-way valve, liquid receiver and one way valve.

5. Hydraulic circuit built with galvanized pipe, complete with water discharge connection for shell and tube heat exchanger and flange type hydraulic connectors.

6. Electric panel consist of: Compressor contactor, fan motor contactor, compressor isolating switch, fan protection breaker, phase sequence relay and microprocessor with function display.

7. Automatic operation dramatically reducing maintenance cost thanks to reliable microprocessor system. Get a quote about Air Cooled Scroll Chiller.

Note:

1、Above parameters refrigerating capacity based on the condensation temperature 40℃, evaporation temperature 2℃。

2、Above is my company's industrial water-cooled water chiller parameters,evaporator is shell and tube type, if there is a demand for the built-in bank、non-standard products of water pump, can be designed and manufactured according to the concrete situation.

3、In order to ensure technology constantly updated, the above parameters are subject to change without prior notice

4、The specific parameters for non-standard products,welcome consulting our technical department.
