High-Low Temp. Low Pressure Test Chamber

High-Low Temp. Low Pressure Test Chamber

High-Low Temp. Low Pressure Test Chamber
  • Product Description

Product overview:

Chamber structure: High and low temperature test chamber under low pressure is shaped by CNC machine tool. It is beautiful and generous, easy to operate.

The inside of the chamber is made of circular barrel, with air duct and heat exchanger inside, and the radiation layer and heat sink are installed to improve the low-pressure heat transfer.

Control system: Siemens PLC+ Siemens touch screen control system, wincc configuration software.

Refrigeration system: adopting imported-brand cascade refrigeration technology, which can realize the temperature range of - 75 ~ 200 degrees. The internal heat exchanger, plate heat sink and radiation layer use heat conduction oil as the cooling fluid.

Circulatory system: use the secondary circulation system, magnetic pump to transport circulating oil.
