R 744 – THE REFRIGERANT OF THE FUTURE
Carbon dioxide (R 744) is over a thousand times less harmful on the atmosphere than the conventional R 134a refrigerant. It has an excellent cooling capacity, it is not flammable and readily available worldwide at low cost. Leading automotive manufacturers already launched the first car models with R 744 air conditioners.
As a trendsetter and innovation partner for an eco-friendly and profitable A/C service we are pleased to present you the first WAECO ASC service unit for R 744 air conditioners.

CO2 A/C systems and thus the service hoses are subject to high system pressures of up to 180 bar.
Bearing in mind that service hoses are exposed to everyday stress in the workshop anyway. A situation which is difficult to simulate in the laboratory. Bending and compression loads cause hoses to age faster than one would expect. It might lead to the “tearing” of a hose, which causes so-called “hose whips”, which can lead to serious injuries to anyone standing close by. The new WAECO hose package helps to avoid this.
Thanks to the integrated “safety rope” working on CO2 A/C systems becomes much safer.
