The Cat excavator air-conditioning system needs to have precise refrigerant type and injection when adding refrigerants.In general, the air conditioners used in Cat excavators are mostly R134a, but the specific increment will vary depending on the type and specifications of excavators.For the correct completion of refrigerant filling, it is recommended that reference be made to the official maintenance manual provided by the manufacturer or that it be operated by professional engineering and mechanical maintenance technicians.In making refrigerant additions, it is important to ensure that ambient temperatures, pressures and the operational state of the equipment are observed and that the correct notation steps are followed in order to prevent damage to the air-conditioning system or to affect its cooling efficiency.At the same time, environmental and equipment performance considerations should ensure that refrigerants do not leak and are regularly inspected and supplemented.In summary, there are no consistent fixed answers to the question of how much refrigerant is used for the "Cat excavator air conditioner", but the key is to specify the specific type of excavator and to operate according to the prescribed standards.
