Portable Conditioning Units (PCU Series)

Our portable environmental testing chambers provide innovative, practical solutions for our customers, rolling up into any box or chamber that doesn’t have heating or cooling. Conditioned air is transferred via ductwork. These portable conditioners have a wide variety of temperature and humidity controls for use in your lab or in the field.

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