Sirius turnkey thermal vacuum systems for mini and medium class spacecraft

Dynavac has worked closely with leading aerospace companies for over forty years and brings our industry leading expertise to the Sirius family of thermal vacuum test systems.

The Sirius family of standardized platforms covers thermal vacuum test requirements for payloads in the mini to medium satellite size classes with chamber diameters of 3 to 8 feet and lengths up to 10 feet.

These systems offer turnkey operation, and include Dynavac’s HMI and control system- preferred by leading aerospace companies.

A choice of thermal platforms provide accurate and stable thermal environments based on test requirements and available facility utilities:  Sirius-MR with mechanical refrigeration, Sirius-LN2 with direct-injection liquid nitrogen cooling, and Sirius-GN2 with Dynavac’s Thermal Conditioning Units (TCUs) to heat and cool using gaseous nitrogen.  Active platens and thermal shrouds are fully integrated into the control system.

Sirius thermal vacuum systems can be configured with a standard array of options, or fully customized to meet unique test requirements.
