Our Low Emission concept explained

Without low emission

Refrigerant discharge without Low Emission: The A/C system is not emptied completely. The remaining refrigerant generates a residual pressure of about 500 mbar (absolute pressure).

Vacuum phase without Low Emission: The remaining refrigerant (500 mbar) is discharged into the atmosphere via the ventilation side of the vacuum pump. Depending on the service unit this amounts up to 10 % of the refrigerant to be recycled.

Used oil discharge without Low Emission: The refrigerant contained in the used oil escapes through the vent holes of the used oil container into the environment. Depending on the service unit the loss amounts to 40 – 100 g per service.

With low emission

Refrigerant discharge with Low Emission: The compressor discharges the refrigerant from the A/C system up to a residual pressure of about 500 mbar. Then the deep-discharge with the Low Emission technology starts.

Deep-discharge with Low Emission: The compressor teams up with the vacuum pump to achieve a genuine
deep-discharge of almost 100 %. As a result, virtually no refrigerant is lost.

Used oil discharge with Low Emission: The refrigerant is discharged by the vacuum pump from the hermetically sealed used oil container and then returned to the refrigerant tank by the compressor. That means you also recover the refrigerant contained in the used oil.
