For maximum accuracy, repeatability, and stability, complete all of your environmental testing with our conditioned air supply systems. Delivering air at precisely controlled temperatures, humidity, and pressure conditions, our systems are able to provide for a wide range of applications and industries. Trust Tescor to build the conditioned air supply you need. The Conditioned Air Supply System consists of an Air Conditioning Unit (ACU) and a Pressure Control Unit (PCU). The ACU draws in outdoor air, cools and dehumidifies the air, and then re-heats and injects steam to regulate temperature and humidity levels. The PCU utilizes a receiving chamber and linear control valves to feed the correct amount of air to the test unit while maintaining a constant flow of air through the ACU to maintain maximum stability.
