Product Description

Please Note!!!  

We can customize different kinds of chillers and central air conditioners according to customer request. Welcome to contact us for details, we will provide professional solutions for you.


 

HIGH-EFFICIENCY COMPRESSOR
The highly efficient semi-hermetical twin-screw compressor adopts the world-class latest generation 5:6 patented asymmetric tooth-type rotor to greatly improve the adiabatic efficiency.

LOW-NOISE OPERATION
The unit adopts the low-noise type outer rotor axial flow fan with long type air duct for diversion to effectively reduce the airflow noise.

THROTTLE APPARATUS
The unit uses the world's most advanced electronic expansion valve, which ensures excellent performance both under full load or partial load and higher control accuracy.

 

CONVENIENT INSTALLATION

 * The unit can be directly installed outdoors without the cooling tower. The compact structure of the unit takes small space and is cost-saving. 
 * The water pipe of the water-side heat exchanger has been equipped with the water flow switch and is ready to use, which saves the on-site            installation time. 
 * Inlet and outlet pipes are clamped, which makes the on-site installation easier. 
 * The unit comes with the startup cabinet and control cabinet and has been filled with refrigerant and refrigeration oil before delivery. Only the water pipe and power supply need to be connected upon installation on site. 
 * The built-in hydraulic module of the unit is optional. This module integrates all necessary hydraulic components such as the water pump, filter,       expansion tank, flow switch, safety valve, pressure gauge, and drainage valve. Customers can debug the running after connecting the water pipes at ends.
