Product Description

　一、Product Description

　　 Water cooled chillers are widely used in the comfort central air conditioning system of hotels, shopping malls, office buildings, exhibition halls, airports, gymnasiums and other public facilities.

　　CTESL series water-cooled chiller is a mature and shaped product developed by Shandong Zhongkeneng Artificial Environment Co., Ltd. on the basis of fully absorbing the latest developments in international and domestic refrigeration and air-conditioning fields. The unit is designed and manufactured in strict accordance with international industry standards. The unit adopts high-quality, high-reliability compressors, refrigerant system control components and computer control components produced by world-renowned manufacturers. Through reasonable system matching and structural design, the unit has high energy efficiency ratio, stable performance, reliable quality and Low noise, no pollution to the outdoor environment and many other advantages.

二、Features

1. Wide selection

　　The refrigeration capacity of this series of units ranges from 75KW to 3350KW.There are a variety of specifications to choose from.Each type of unit has two types of control methods:ordinary computer control and luxury computer control.And other non-standard products.

　　a Single compressor series

　　b Double compressor series(single evaporator type)

　　c Four compressor series

2. Rigorous design and excellent options

　　Fully consider the domestic actual operating conditions,carry out reasonable system configuration,and optimize the selection of each component to minimize the energy loss of each refrigeration component and improve the efficiency of the unit.The compressors,refrigeration system accessories,computers and electronic control components used by the unit are imported from famous foreign companies,with good quality,accurate control,reliable performance,strong adaptability,simple maintenance and high operating efficiency.

3. Complete protection,stable and reliable operation

　　The units are equipped with protection devices such as temperature protection switches,overload relays,high and low voltage safety switches,drying filters,antifreeze switches and delayed start,to ensure the safety of the host,and easy maintenance and maintenance.According to the fuzzy adjustment,the user load is dynamically detected,the unit operation energy adjustment is performed,and the load is dynamically matched.Complete operation monitoring and fault diagnosis functions ensure the safe and reliable operation of the unit.

4. Advanced control and reliable performance
