Liquid cooler

The PTLQ series gas refrigeration machine is mainly composed of a refrigeration system, a heat exchange system, a control system, a casing, etc. The refrigeration system adopts steam compression refrigeration

Rapid cooling: A self-designed high-efficiency heat exchange system, where dry compressed air or nitrogen at room temperature is introduced into the PTLQ gas refrigeration machine, and the gas produced can reach the target low-temperature temperature.
Integrated structure: The entire system has been assembled in the factory, and users only need to install the power supply, gas pipeline, and cooling water pipeline to start up and run.
Explosion proof design: Various types of explosion-proof designs can be customized according to the actual usage needs of customers.
Efficient heat exchange system: The evaporator uses plate heat exchangers. Some products may use finned tube heat exchangers, which have high heat exchange efficiency, compact structure, high pressure resistance, and a pressure capacity greater than 2.5MPa.
Control repeatability: Based on advanced dynamic control systems, consistent control results can be achieved every time, greatly improving the stability of product production.
Temperature control system: A self-developed temperature control module that changes the control setting method to quickly respond to system lag during the process and obtain the minimum temperature overshoot. The control consists of two sets of PID (each set of PID is variable) control loops, which become the main loop and the slave loop. The control output of the main loop serves as the set value of the slave loop. The system adopts a feedforward PV, and the output of the PID operation result of the main control circuit is combined with the feedforward PV signal as the set value of the main control circuit. By doing so, gradient control of temperature changes is carried out to ensure the temperature accuracy of the system.
Quality assurance: All key components are selected from imported brands or domestic first tier brands to ensure long-term reliable operation of the products. At the same time, all products undergo strict testing and inspection before shipment to ensure that there are no problems with the equipment when it arrives at the customer's site.
