Psychrometric Chambers
The Core of our Business.
Psychrometric testing facilities are our core business. We provide turnkey solutions for all types of HVAC systems and equipment. The Psychrometric Chamber Test System provide full ARI and ASHRAE calculations and methods. The system is very versatile and can be configured to use existing front-end measuring and control hardware on existing rooms. All components of the system can be customized as needed to meet customer requirements.
Typical psychrometric test rooms contain a Data Acquisition and Control Unit (DACU). The DACU provides continuous monitoring of various TC, RTD, volts, amps, watts, watt-hours, flows, and pressures. Each DACU contains front end measurement devices and/or analog PLC’s, power supplies and I/O terminals. All equipment is housed in a NEMA 12 enclosure for location near the test chamber.
