W-Series test chambers

W-Series test chambers


Russells Technical Products W-Series welded construction walk-in/drive-in chambers are ideal for high temperature and high humidity simulation. Their solid, one piece construction allows for rapid thermal change rates, ultra low temperature cooling, and prolonged soaks at extreme temperatures. With a wide variety of plenum options and configurations, our W-Series test chambers can be designed to meet your exact specifications.

Moisture buildup can be destructive to products, especially electronics, causing corrosion and oxidation. Russellssolid construction W-Series temperature and humidity test chambers afford maximum durability and performance for your most demanding simulation test requirements.
