Our Low Emission concept explained

Without low emission

Extraction without low emission, the air conditioner is not completely emptied. The compressor of the service unit is not able to empty the system complete a residue of 500 millibars (absolute pressure) of refrigerant remains in the air conditioner.

Vacuum phase without low emission, the remaining refrigerant (500 millibars) is extracted through the exhaust side of the vacuum pump, depending on the device between 1 and 10%.

Oil drainage without low emission, the refrigerant needed for draining the used oil escapes into the environment through the ventilation holes of the old oil container. For each used oil drain operation, depending on the device, it is between 40 and 100 grams.

With low emission

Extraction with low emission, through the collaboration between the compressor and the vacuum pump, emptying of almost 100% is achieved and no refrigerant is lost.

Used oil drainage with low emission, the refrigerant needed for the drainage of the used oil is extracted through the vacuum pump out of the hermetically sealed used oil container and filled into the internal tank via the compressor. No refrigerant is lost!
