With this innovative technology, we offer garages a method of leak detection in passenger car and commercial vehicle A/C systems that saves time and money while protecting the environment. Once the A/C system has been filled with forming gas, vibration leaks that are difficult to detect can be identified with variable adjustment of the pressure. The location of leaks using forming gas, which is 95 percent nitrogen and 5 percent hydrogen, is particularly efficient as even the smallest leaks can be found in leaking A/C systems. SELECTH2 – THE BEST DEVICE FOR DETECTING LEAKS IN A/C SYSTEMS The SelectH2 selective gas detector is equipped with two gas sensors, which act like an artificial nose and only respond to hydrogen. Gas and oil vapours do not have a negative impact on the measurement result, so there is no longer any obstacle to effective and precise leak detection on your car or air conditioning system. This is the key difference compared with conventional detection units, which respond to the refrigerant R134a. Mit dem Laden des Videos akzeptieren Sie die Datenschutzerklärung von YouTube.

The A/C system can also be filled with forming gas via the low-pressure connection. This means the forming gas can be distributed through the system more quickly and evenly. Expansion set Adapter for low-pressure and high-pressure side Online-Catalogue 123 EVACUATION Evacuate the air-conditioning system using a suitable A/C service unit. FILLING A/C SYSTEM WITH FORMING GAS 95/5 Now fill the high-pressure side of the air-conditioning system with forming gas. The high and low-pressure side can be topped up simultaneously using the leak-location expansion set. HEATING UP THE DEVICE The heat-up phase of the SelectH2 is signalled by the word "HEAT" and lasts approx. 50 seconds. LOCATION OF LEAKS WITH OUR SELECTH2 Guide the gas detector over the hose connections and components at a steady speed. You can read the respective hydrogen concentrations off the display. Rising ppm values indicate a leak. LOCATION OF LEAKS Leaks are also indicated by acoustic and visual signals. REPAIR AND INSPECTION After repairing a leak, it is recommended carrying out another inspection using forming gas, followed by a functional check. FILLING WITH REFRIGERANT AND TESTING FOR LEAK-TIGHTNESS Fill the air-conditioning system with the appropriate refrigerant. Once you have filled up the A/C system, you should perform a functional test without fail. SIGHT GLASS FOR REFRIGERANT ANALYSIS Our sight glass enables visual inspection of refrigerant or compressor oil and provides valuable information on their condition. Chips for example or other foreign bodies may have got into the system. You can also check whether compressor oil has become discoloured or contains water. Important information: The connections for R134a or R1234yf must be ordered separately. With integrated filter Easily disassembled for cleaning Online-Catalogue FIND THE SHOPS AROUND YOU!
