Maximum Environmental Testing Flexibility

  • Portable Environmental Conditioners The PCU-Series On-The-Spot Environmental Conditioning for Maximum Testing Flexibility

    Russells PCU- Series, portable conditioning units give you the maximum environmental testing flexibility.

    These are environmental testing chambers that we have developed over the years since our inception in 1972 to provide innovative, practical solutions for our customers. If you have a box or chamber with no heating or cooling, our portable units will easily roll up to your box. We then transfer the conditioned air via ductwork. Your Russells portable conditioner will have a wide variety of temperature and humidity control uses in your lab and in the field including:

    • Vibration Testing
    • Automotive “Squeak and Rattle” Testing
    • Custom Test Enclosures
    • Environmental Stress Screening (ESS)
    • Material Testing
    • Spot Heating and Cooling
    • Environmental Forced Air for Avionics Testing
    • Ordinance Temperature Conditioning
    • Elite PCU’s double as a stand alone test chamber
  • Benefits of Russells Environmental Chambers

    Test chambers from Russells Technical Products give you our combination of years of design, application, and manufacturing experience backed by an experienced service group to meet your testing needs. The fastest technology and state-of-the-art instrumentation are incorporated into every chamber we build. Competent design, practical application, on-time delivery, and qualified service are but a few of the benefits that Russells customers expect and receive.

    A Russells application engineer can assist you in selecting the portable conditioning unit configuration, options, and size that’s best for you, custom designed to your exact specifications.


  • Temperature range for mechanical refrigeration, single stage: -4°F/-20°C to 350°F/177°C
  • Temperature range for mechanical cascade and LN2 refrigeration: -100°F/-73°C to 350°F/177°C

Humidity (PCUD Models)

  • 20%RH to 95%RH in the range bounded by an 185°F/85°C maximum temperature and a 40°F/4°C minimum dewpoint.

Russells PCU’s are available in a variety of air flow, cooling and heating capacities. A Russells application engineer can assist you in selecting the chamber configuration and size that is most economical for your testing needs. Let Russells give you the competitive edge!
