Our visits will save you money. With regular planned, preventative chiller maintenance our engineers will get your plant running better than when it came out of the factory!
Live Electrical Testing
We are trained and certificated in live electrical testing end electrical fault finding. Risk assessment method statement is used to control the risks. Rubber mats below panel are used as well as non conducting boots

In a fridge system it is very important to know the superheat value of the low side of the system. During the chiller service 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 to ensure the fridge system is running 100% efficiently
Chiller Service Faults
A lot of faults can be rectified with the stock of parts and materials that the engineer carries in his car. While we are on the chiller service 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 machine. 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 worst thing that can go wrong with a chiller is an evaporator freeze-up. It can happen for a variety of 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 pick up the pieces?
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 labour costs outweigh a replacement- so the chiller is ruined
What can be done to prevent this?
Regular maintenance is essential to stop this happening and to prevent other small problems becoming big ones. If, however, your chiller does need repair, at Maximus Chillers will get your chiller working better than when it came out of the factory!
