The main goal of fridge/refrigerator recycling is the save removal of all fluids and gasses from the unit.
Our systems can degas refrigerators containing the following gasses
NH3 (ammonia) (Been that absorber refrigerators containing ammonia are very different from the standard domestic refrigerators and are therefore not described on this page. You can find out more about these type of recycling systems here.
Fast degassing by penetrating the compressor
In order to drain the gas and the oil it is necessary to penetrate the cooling system. Penetrating the lines of the cooling system will course a problem because of the oil that is left in the compressor ( see piercing-pliers). The in the compressor remaining oil starts to degas the moment the pressure is going down. This is the reason why it takes so long to degas a fridge with a piercing pliers.
Because regulations say the draining of oil and gas has to be done in one handling the best way is to penetrate the compressor. Penetrating the compressor with a vacuum drilling-head enables you to take out the oil and the gas in one handling. This goes much quicker then when you penetrate the line because the oil degasses in the degassing machine and not in the compressor of the fridge.
Oil and gas separated
The oil and the gas are separated in the machine and stored in the proper external tanks.
After the oil and gas is removed the compressor has to be cut from the fridge itself.
We also designed a device to block the lines ingoing and outgoing the compressor and cut it in the same handling. After that it is possible to drain the oil and gas on an automatic degassing unit. This saves the handling of the complete fridge and makes the degassing independent from the stage 2 shredding unit. It will increase the capacity of the whole process. By doing this a small amount of the cooling gas will come into the second stage. shredder and will be collected there . Using the ATN G(as) T(reatment) P(lant) this will be no problem. In order to find out whether or not it will be a problem for your second stage you have to ask your supplier.
Up to 200 refrigerators an hour
The capacity of the total unit can go up to 200 fridges per hour. Of course the capacity depends on the bottle neck of the total refrigerator recycling plant. But you have to realize that the more expensive second stage has to run flat-out because that is the most efficient way for your investment. We supply machinery to customers that can do 200 fridges per hour.
