The pvd coating machine water chiller plays a key role in the machine. When purchasing the vacuum coating machine, some manufacturers will pay special attention to the brand, performance, and some working principles of the water chiller. Because the success rate of the later coating layer has a direct relationship with the water chiller, the following is a summary of the vacuum section to introduce in detail the specific role of the water chiller in the pvd coating machine?

The vacuum water chiller is widely used in industrial refrigeration. It can provide constant flow, constant temperature, constant pressure, and control the temperature of the vacuum coating machine. Different technological processes need to control different temperatures. The water chiller in the pvd coating machine can be divided into air cooled water chiller and water-cooled water chiller. The water-cooled water chiller can achieve good cooling effect plus cooling tower. The air cooled water chiller has requirements for the working environment. It is cooled by hot air circulation, The ventilation effect directly affects the cooling effect of the chiller.
The chiller shall be capable of water temperature regulation and control, and shall not be affected by temperature and environment; The performance shall be stable to ensure no failure in case of continuous operation for years; Energy saving and power saving, self regulating function, effective power saving; The noise shall be low, and there shall be phase loss, phase staggering, current overload, high and low voltage protection systems. The pvd coating machine is equipped with a water chiller to achieve the purpose of high efficiency and high-precision temperature control to ensure the high quality of the plated parts, increase the density and smoothness of the plated parts, shorten the electroplating cycle, improve production efficiency and improve product quality.
The special water chiller for pvd coating machine is mainly composed of compressor, reservoir, drying filter, thermal expansion valve, evaporator, refrigerant and condenser. The compressor is the heart. The chiller refrigeration system inputs electrical energy through the compressor to flush the heat from the low temperature environment to the high temperature environment. The refrigeration compressor determines the efficiency of the entire system. The liquid receiver is installed behind the condenser and directly connected with the liquid discharge pipe of the condenser. The liquid receiver plays the role of adjusting and storing refrigerant.
