STANDARD CYLINDRICAL TVAC SYSTEM RATED -40° C TO 80° C, front view chamber door open STANDARD CYLINDRICAL TVAC SYSTEM RATED -40° C TO 80° C, front view chamber door open

A product-oriented space-technology company required a Thermal Vacuum Cycling Test  System with several custom conflat electrical feedthroughs to test and qualify their highly sensitive components that will be subjected to the extreme temperatures of space.

LACO’s team of engineers configured a standard Frontier thermal vacuum solution based on our standard FST2020 platform. Utilizing the Refrigerated-Heated Circulator combination, we delivered an effective and cost-efficient solution. This unique solution has a temperature rating of -60 °C to +150 °C which meets and exceeds the thermal requirements outlined by the customer.

Our FST Cube Thermal Cycling system meets NASA GSFC-STD-7000 standards for vacuum bake-out, temperature margins, thermal cycling, soak time performance, and pressure.
