CCT high-pressure/temperature sensor

For air-conditioning systems with CO2 heat pump

The CCT high-pressure/temperature sensor was specifically developed for the high pressures and temperatures in CO2 heat pumps (R744). R744 transports significantly more heat than conventional refrigerants and is also climate neutral, non-flammable and almost odourless.
