●Developed separately for various environmental equipment, can be unified with software centralized computer control, the controller interface style is consistent, convenient for user operation;
●Adopt PLC program control, with timed operation, stop function, power-off protection function, good stability;
●Can be connected to centralized monitoring software, and provide communication protocol, convenient for users to carry out secondary development; can remotely monitor multiple test boxes.
Refrigeration System Description
● Use imported parts from internationally renowned brands, ensure high performance of test chamber in semiconductor industry;
● Use imported parts from internationally renowned brands;
● Use composite refrigerants with zero ozone depletion coefficient;
● All condensers are equipped with filtering devices to ensure long-term and reliable operation of the unit;
● Intelligent control of the refrigeration system adapts to a wide range of loads and consumes less power in operation;
● Use imported compressors: Taikang compressors, which have lower operating noise and more stable performance;
● All pipelines are protected by nitrogen before welding to ensure that the inside of the copper pipe is not oxidized, and the surface of the weld is coated with varnish for protection. It is one of the manufacturers in the industry that meets this standard;
* Modular production of refrigeration units is divided into three modules: sub-assembly, sub-assembly and general assembly; establish a pipe bending manual to ensure the uniformity of the system. Standardized modules are easy to install, debug and maintain.
