Your star turn for servicing CO2 air conditioning systems


CO2 air conditioning system (R744) is superior to the current R1234yf system in terms of efficiency, cooling dynamics and environmental sustainability. Reputable automotive manufacturers have recognised its potential and will in future be putting their faith in CO2, the natural, ecological and advanced coolant. AVL DITEST is supporting the automotive industry with unique, state-of-the-art innovations. Together, we have developed the VAS 581 009 air conditioning service device so that for the first time, garage workshops are also able to carry out repairs and maintenance on CO2 air conditioning systems. Safety, environmental protection and economic efficiency were, of course, at the forefront of the development programme for the device.
