Test your heat exchanger capacities and/or refrigerant properties in these state-of-the-art, temperature-controlled chambers. Our Calorimeters are not limited to testing fluid to air heat exchangers, you can also add the capability to test fluid to fluid exchangers. These surface calorimeters utilize temperature-controlled chambers to control the air temperature over the heat exchangers. The calorimeter offers control over parameters such as ambient temperature and humidity, test piece air flow, compressor speed, discharge pressure, condenser inlet temperature, expansion device inlet temperature, suction temperature, heater core inlet temperature, pressures and flows, etc.
