The PCU-Series From Russells Technical Products

On-The-Spot Environmental Conditioning for Maximum 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 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
