Tenney Environmental Ships Vacuum Space Simulator to Aerospace Industry

Posted: Jul 18, 2018

Tenney Environmental, announced the shipment of a vacuum space simulation system. This system is designed to test ionic thruster chips for space vehicle systems. The simulator will allow the customer to test their products in house, while replicating outer space conditions. The customer manufactures equipment for space.

The dual cryopump vacuum system is sized specifically to maintain the high vacuum while the thrusters are firing inside the vessel. The Tenney space simulation chamber design considers the OSHA, NEC, and ASME Code for Unfired Pressure Vessels.

The vacuum chamber is a horizontal cylindrical vessel constructed entirely of Type 304 stainless steel with a #4 interior and exterior finish. The overall internal dimensions of the vessel are 48” in diameter and 60” in depth. The vessel also includes multiple specialty access ports and an internal stainless steel removable grating shelf system, so the customer can place his products inside as needed.

“Tenney designed the cryopump control system to allow the customer the flexibility to automatically run one or both of cryopumps independent of each other using proprietary control logic for the gate valves. This provides the customer more gas load testing capabilities.”

– Rick Powell, Vacuum Products Manger
