Calorimeter

Compressor calorimeter cart

Overview

Designated for the commercial and vehicle HVAC compressor testing industry. Two available performance options including durability or calorimetry.  Critical data collection includes accurate measurement of capacity, power input, as well as various measured and calculated performance values. System can be designed to perform within the prescribed operating ranges of R-134A, R-1234yf, R-404A, R-410A, R-744A and R-22. Other refrigerant designations can also be considered.
