Product Description：
Name：0.1kpa low pressure high and low temperature test machine
Type：BND-PTD-1000S
1,This equipment mainly consists of five basic parts: test box, temperature circulation system, low pressure vacuum system, and program control system. among them:
1. The test box includes the pressure vessel, the door, the insulation layer, the shell seal, the test signal lead-out hole and the external flange, and the indoor lighting.
2. The temperature cycle system includes a refrigeration system and a heating system. The refrigeration system includes the original German blog semi-hermetic compressor, Danish Danfoss expansion valve, DuPont Refrigerant, Taiwan Collier plate heat exchanger, US TEMPRITE oil separator, Danfoss Denmark or the same brand of solenoid valves. The heating system includes electric heaters, using domestic brands and mature technology and reliable materials.
3. Low pressure vacuum systems include imported brands of vacuum pumps, vacuum gauges, vacuum electromagnetic block valves, vacuum bleed valves, vacuum trim valves, oil traps, pipes and hoses, and standard connectors.
4. The control system uses Chinese and English interfaces, and the control system uses self-developed software. The control system selects the brand components and controls the low pressure system, temperature circulation system, refrigeration unit, valve opening process, and test data processing (acquisition, storage, download).
