Intlvac Thermal Vacuum System

Intlvac’s Thermal Vacuum System is a versatile space simulation system, with a vacuum chamber constructed from 304 stainless steel, measuring either 36” x 36” (.9m x .9m) or 59” x 78” (1.5m x 2m).  The chambers are designed to provide an extensive environmental test complex to simulate the outer space and varying thermal conditions. It allows for a variety of parts to be tested in a <10-6 torr vacuum, in a dry pumped, clean environment.  

Each chamber is fitted with either a turbo pumping system or cryogenic pumping system.  Multiple thermocouples and a readout system are included for monitoring items under test.

Intlvac’s fully automated PLC system controls all pump-down venting, cryopump regeneration cycles, and also allows researchers the option of manual operation.  Efficient isolation between the thermal simulation shroud, and the high vacuum chamber, assists and controls stability and temperature rates.

LabVIEW software is used as the computer operating system and is expandable to meet the user’s needs.  A Polycold refrigeration unit is used for platen cooling.  A series of cartridge type heaters are used for heating.  The temperature control is accomplished using a full PID controller, allowing for temperature ramping and soaking.
