Servicing domestic hydrocarbon fridges
GERMANY: Compressor manufacturer Secop has worked with mechanical tube connection company Vulkan Lokring to produce a step-by-step video on how to service R600a and R290 Secop compressors in domestic refrigerators.
Recognising that a key challenge in the transition away from HFCs is training, the refrigeration duo point to estimates that only 10% of technicians are educated to handle natural refrigerants including CO2 (R744), ammonia (R717) and hydrocarbons (R600, R600a, R290).
The new Secop/Vulkan Lokring 17-minute video updates a previous video which received 51,000 views. It covers the following topics:
Troubleshooting/how to check the refrigeration circuit
Refrigerant disposal (for natural refrigerant compressor models only)
Disassembling the compressor/filter dryer
Assembling the filter dryer/compressor with specific Lokrings
Evacuating and charging (0.060kg of R600a)
System checking/sealing/safety testing
Secop is the former Danfoss Household Compressor business acquired by German holding company Aurelius in 2010.
