High temperature cleaning system for test chamber

This equipment is equipped with a high-temperature cleaning system. It has a high-temperature cleaning system. It uses high-efficiency electric heating equipment to heat the inner wall of the test chamber. The high-temperature cleaning temperature can reach 250 °C. The thermal efficiency is high and the energy consumption is low. produce environmental pollution. It has a complete monitoring and alarm device, which monitors the running status in real time during the entire high-temperature cleaning process, and has heater overheating, overcurrent, and overheating and overpressure protection alarms in the cabin to avoid damage to the equipment during the high-temperature cleaning process.

The test chamber adopts the one-time forming technology of thermal welding. After welding, high temperature treatment is performed to control the deformation of the chamber body within a certain range during high temperature cleaning. At the same time, our company's unique elastic connection technology is used to make the heating process The thermal deformation of the medium is eliminated in time after cooling, which effectively prolongs the service life of the equipment.

13

Measurement and control system

Using high-resolution intelligent touch screen controller and Siemens PLC, the temperature, humidity, dew point temperature, working time, gas flow and other parameters of the climate chamber can be set through the touch screen; the operation process of the equipment is simple and intuitive, and the experiment can be carried out according to the prompts. With U port, data can be exported. It can be monitored by computer terminal or mobile APP.
