Envirotronics Star Galaxy™ 44 is a test chamber with an integrated vibration table that has been specially designed to perform HALT and HASS processes. Star Galaxy chambers are equipped with a Liquid Nitrogen ( LN₂ ) cooling system.  The LN₂ cooling system, with modulating valve and directed airflow to the product, provides the rapid thermal change rates required to achieve maximum product stress. Additionally, these rates are accomplished with smaller space requirements, lower audible noise, no water requirement, and lower maintenance costs than a typical refrigeration system.

The large mounting area of the 44 in. table, comprised of a product mounting configuration of 3/8 in. holes in a 4 in. by 4 in. mounting pattern, allows great flexibility in mounting your product or fixturing. Our improved-efficiency pneumatic vibrators deliver your required vibration energy while utilizing 20% less air. This translates into savings for you.

The combination of Envirotronics’ control system, which gives the user the flexibility to control via one accelerometer or any combination of 4 accelerometers, and our adjustable air flow package that allows the user to redirect airflow to the product under test puts control in the hands of the Star Galaxy user. It’s time to shoot for something better -
Shoot for the Stars!
