Product Description

Close to 100 % discharge in four steps

Most A/C service units available in the market today are using three major process steps: refrigerant recovery via the compressor, evacuation of the refrigerant circuit via the vacuum pump, and refrigerant recharging. WAECO ASC Low Emission service units are using an additional process step to ensure that close to 100 % of the refrigerant can be recovered.

In this process step the vacuum pump teams up with the compressor to recover also the residual amount of refrigerant contained in the oil. This additional step – indicated by the orange ECO LED on the new operator display – gives two major advantages. First, there’s virtually no refrigerant lost or escaping into the environment. Second, the exact amount of the recovered refrigerant can be identified in the subsequent weighing. This avoids misinterpretation with regard to the tightness of the A/C system, which would otherwise lead to unnecessary troubleshooting and costly repairs.

The 4 steps of the WAECO Low Emission service process

Refrigerant recovery: The refrigerant is recovered from the vehicles A/C system with the help of the compressor of the A/C service unit.

Used oil drainage: The vacuum pump teams up with the compressor to recover also the residual amount of refrigerant contained in the oil, also during the drainage of the used oil. No refrigerant lost or escaping into the environment.

Vacuum phase: The vacuum pump is switched on automatically and ensures deep down evacuation of the A/C system. Since the vacuum pump is connected to the internal container of the Low Emission service unit, the refrigerant does not escape into the environment now, but is collected in the internal container.

Refrigerant recharging: The A/C system is charged with the vehicle-specific amount of refrigerant from the tank of the A/C service unit.

Please note that the sustainable and economical use of R 134a will be an issue of growing importance in the future!
The EU directive about the shortage of available R 134a resources has already been in force since 1st January 2015.


The new F-gas regulation of the European Union has been in force since January 1st 2015. Aiming at a reduction of the use of fluorinated greenhouse gases, it regulates, among other things, the import quantities for the marketing of R 134a refrigerant. One thing is for sure already: R 134a is going to run short and will become very expensive. Refrigerant loss will be something no workshop can afford in the future.

Invest in a low-emission service unit now to be able to offer your customers an attractive and cost-efficient A/C service in the long run. Dometic WAECO’s well engineered low-emission concept keeps you a step ahead of your competitors.

Low emission service unit for R 1234yf
with integrated gas identifier

They may be only a few, but they are there – the first new vehicle models with A/C systems prepared for the use of R 1234yf refrigerant. Brand-bound motor garages, in particular, are obliged to get prepared for servicing these systems. Against this backdrop WAECO’s AirCon professionals have designed, in close cooperation with the automotive industry, the ASC 5500 G RPA Low Emission service unit.

As R 1234yf is very sensitive to contamination with other refrigerants, the ASC 5500 G RPA Low Emission was fitted with an integrated analysis tool that checks the refrigerant purity.

Designed inside out for use with R 1234yf refrigerant, the ASC 5500 G RPA Low Emission meets fire regulations and offers all the benefits known from the “classic” models in the ASC series.

Extra safety

The service unit comes with integrated refrigerant analysis function. Explosion protection: hazard analysis performed by an independent test institute.

Automatic, regular leak check

Automatic leak check prior to service start

Switch-on delay and external ventilation

R 1234yf is flammable under certain conditions. Therefore, the system start will only activate the external fan. After the fan has been running for 35 seconds, the voltage is passed on to the system.
