WAECO Low Emission
Save costs and protect the environment
Almost 100% refrigerant recovery
Using the WAECO ASC Low Emission technology, almost 100 % of the refrigerant can be recovered during A/C service. How does it work? Refrigerant loss mainly occurs in the phase when the refrigerant is forced out from the refrigerator oil by means of the vacuum pump. ASC Low Emission service units collect the escaping refrigerant in a hermetic, pressure-tight used oil container, recover it and return it to the refrigerant tank. The result is a refrigerant loss rate of close to zero percent!
The accurate identification of the amount of recovered refrigerant also allows conclusions to be drawn about the tightness of the air conditioner (diagnosis tool).
Low emission pays off!
Scarce refrigerant resources and soaring prices are hot topics when it comes to the service of vehicle A/C systems. In the period from August 2017 to August 2018 alone the price for one kilogram of R134a rose from about 17 € to about 46 € – and this trend is bound to continue.
The WAECO Low Emission service technology gives you an economical, safe and environmentally sound solution – for conventional R134a A/C systems as well as for the alternative R1234yf refrigerant.
The benefits:
- Close to 100% refrigerant recovery
- Virtually no harmful emissions
- No money lost unnecessarily
Environmentally sound and profitable
R134a has been prohibited for new type approvals since 01.01.2011 and for factory-fills of all new vehicles since 01.01.2017 (valid for vehicle categories M1 and N1) due to its high GWP (global warming potential). Unlike with R12, using R134a for service and repairs is not prohibited. The Regulation EU 842/2006 defines the maximum quantities of refrigerant to be imported from non-EU countries, which now leads to the price increases.
R1234yf has been used since 01.01.2011 for new type approvals in the automotive industry. R1234yf has a lower GWP than R134a, but it is significantly more flammable. A conversion similar to that from R12 to R134a is not taking place for technical reasons.
The WAECO Low Emission service concept gives you an economical, safe and environmentally sound solution – for conventional R134a A/C systems as well as for the R1234yf refrigerant. The benefits: close to 100 % refrigerant recovery, virtually no harmful emissions and no money lost unnecessarily.
