Portable Conditioning Units (Remote Conditioners)

Russells Technical Products portable conditioning units provide innovative, practical solutions for customers across a variety of applications. Offering a robust range of temperature and/or humidity capabilities, these units will condition existing environmental test chambers, temporary test spaces, and custom remote enclosures.
With options for single-stage or cascade refrigeration, or LN2 cooling, virtually every environment is attainable with our portable conditioning units. A Russells mechanically cooled PCU offers robust environmental testing flexibility, while LN2 cooling provides a wider cooling range and expedites temperature pull downs for your more extreme testing needs.
