Compressor Calorimeters

Climatic Testing Systems, Inc. (CTS) designs and manufactures A/C Compressor Calorimeters in accordance with ASHRAE Standard 23 and ISO Standard 917. The calorimeters are provided with a secondary refrigerant calorimeter vessel and Micro Motions® coriolis mass flow sensor to provide accurate and repeatable determination of compressor capacity.

CTS calorimeter systems feature PID control with solid state sensors. Various refrigerant types such as R-12, R134a, R404a, R407C, R410a, R507, R600a and others can be tested. The calorimeters can be designed for capacities up to 200,000 BTUH (60 Kw) with an energy balance of 2% or better, and 1% repeatability.
