Application of PTLQ series gas refrigeration machine products

The PTLQ series gas refrigeration machine is used for gas cooling and cooling, and can also be selected for temperature rise and constant temperature control. The gas is usually dry compressed air or inert gases such as nitrogen and argon. The intake temperature can be at room temperature or high temperature, and is lowered to the target low temperature through a gas cooler. For the application of wafer testing cold stage, gas refrigeration machines have many advantages compared to traditional liquid cooling, such as ease of use, safety and hygiene, low cost, and no odor. Customers can choose equipment based on gas processing flow rate and temperature. The system mainly consists of a refrigeration system, a heat exchange system, a control system, and a casing. The refrigeration system adopts steam compression refrigeration, and the compressor and main refrigeration components are all from international brands. The heat exchange system consists of high-efficiency heat exchangers, connecting pipelines, insulation, and other components. The control system adopts Siemens PLC and adaptive PID control algorithm, which can achieve optimal temperature control without changing parameters in different usage environments and loads. High definition touch screen display, comprehensive security protection measures, and multiple security protection mechanisms are set up to ensure the safe operation of the system. Controller Internet of Things, which allows remote viewing of data, alarm information, and remote control through a mobile app; Optional cooling capacity recovery device can be equipped to improve energy efficiency and avoid low-temperature condensation water. Through the unit's own refrigeration, the dry gas entering the device is cooled and kept at a constant temperature to meet the process requirements.
