Refrigeration & Air conditioning technology

Safety precautions must be observed regularly in the refrigeration and air conditioning sector. For example, leak tests (impressions) must be carried out on refrigeration systems, air conditioning systems and heat pumps to ensure that no environmentally harmful refrigerants escape from the system. In addition, evacuation (vacuum pulling) is used continuously before each start-up or after maintenance in order to remove moisture or residual gases in the circuit of an air conditioning system or heat pump.
