New handling system for refrigerator degassing

ATN more and more receives request from customers (especially from outside Europe) for automatic handling systems. Refrigerators are becoming bigger and bigger. In countries like the USA the weight of a fridge can be well over 150kg. In order to avoid manual handling of these big refrigerators during the degassing process ATN developed an automatic handling system, the WM2.

Why handling?

Handling of the fridge is necessary in order to reach the maximum efficiency of the degassing process. The refrigerant can be drained in every position. But in order to drain the refrigerant containing oil in the most efficient way the degassing process has to take place at the lowest point of the compressor. Of course the capacity of the drill-head is not allowed to be limited by this new handling system.


Short description WM2

Over the existing conveyer system the refrigerator is conveyed into the WM2. The WM2 brings the fridge in the correct position for the degassing process. The operator connects the drill-head to the compressor and starts the degassing process. After one minute the degassing process is finished and the drill-head is disconnected. Automatically the refrigerator is turned and brought back into the existing conveyer system. At the same time the next refrigerator is brought into position for the next degassing cycle.



Because the WM2 is working automatically safety is a very important issue. With the help of a number of sensors accidents are nearly impossible.


  • No restriction in the capacity 
  • Maximum safety
  • Easy to install
  • Communicating with the ATN degassing machine
