    Checking the refrigeration circuit

    Regular and accurate checking of the refrigeration circuit is an essential part of ensuring the safe and efficient operation of a refrigeration system. This ensures that all components are working properly and that there are no leaks, pressure drops or contaminants affecting the refrigerant circuit. This keeps the system running efficiently and optimizes energy consumption.
