Chamber Structure

The equipment consists of five basic parts: test chamber, temperature cycling system, low pressure vacuum system and program control system.

 

-Test chamber includes pressure vessel, door, insulation layer, enclosure seal, test signal output hole and external flange, inside chamber lighting, etc.

 

-Temperature cycling system has refrigeration system and heating system.

 

-Low pressure vacuum system includes vacuum pump, vacuum gauge, vacuum solenoid cut-off valve, vacuum relief valve, vacuum trimming valve, oil trap, pipes and hoses, as well as standard connectors.

 

-Control system has English interface, to control low pressure system, temperature cycling system, refrigeration unit, valve opening process, test data processing (collect, store & download), etc.
