Portable Conditioning Units (PCU Series)

Our portable conditioning units provide innovative, practical solutions for our customers. Offering a robust range of temperature only or temperature and humidity, these units will condition existing environmental test chambers and predesigned or custom remote enclosures. Available in single stage or cascade refrigeration, with optional LN2 boost, virtually every environment is attainable with these portable conditioning units.

Russells PCUB/D-810 Mechanically Cooled Temperature or Temperature/Humidity Portable Conditioning Units give you robust environmental testing flexibility for your remote testing needs.
