During a chiller service visit it is very important to know the small difference on the low side of a fridge system. During the visit we work out this value as part of giving your chiller a full health check
This is the value of the high side of the system. This value too is worked out during the chiller service to ensure the fridge system is running 100% efficiently
Chiller Service Faults
A lot of chiller faults can be serviced with the stock of parts and materials that the engineer carries in his car. While we are on the visit we don’t even put this through the books it is all part of the service. As far as we are concerned you are paying for us to be on site and we will do anything to improve the condition of your chiller. This is just part of the way we deal with the customer- you! If we can keep your costs down and keep you happy- that makes us happy!

The industries best engineers
Chiller looked like it was short of gas but to a discerning eye it wasn't- the EEV had failed. The mechanical part of the Electronic Expansion Valve jams up causing the chiller to trip out. A relatively easy chiller repair as it is just a straight swap. The chiller can be pumped down and valved off. The EEV driver is okay. The valve clamps on to the body with a knife edge seal. This particular valve is prone to failure- the other 3 systems across both 0.5 mw chillers has had one fail too
The worst chiller service issue is an evaporator freeze-up. It can happen for various reasons
What happens when the safeties fail?
The compressor carries on running. The evaporator turns into a solid block of ice. Ice has a larger size than water, so as it expands it buckles then bursts the evaporator. The compressor still carries on running. Refrigerant leaks into the water system until the pressure in the fridge system and the water system equalise. Then, water is sucked into the fridge system. It gets sucked into the compressor and round to the condenser. Compressors cannot compress a liquid so a compressor smash-up occurs
How do we service the chiller?
The compressor or compressors need to be re-built. The evaporator needs to have the burst tubes identified then plugged. The system needs to be dehydrated using a vacuum pump which takes several months. On a smaller chiller, the service costs outweigh a replacement- so the chiller is ruined
What can be done to prevent this?
Regular chiller maintenance is essential to stop this happening and to prevent other small problems becoming big ones. If, however, your chiller does need a repair- we at Maximus Chillers will get your chiller running better than when it came out of the factory!
