Chiller Service Visits

When a chiller service visit is scheduled because of the technical complexity of the job, our engineer will be on site at 9am in this country or in any country. We know your plant is critical to the operation of your business, so our work is carried out to the highest standards. Our service visits are often completed to beyond manufacturers’ recommendations so we know that your plant will not fail for the same reason again


The Approach

During a chiller service visit it is very important to know the small difference on a fridge system. While we are on 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 is worked out during the chiller service so as to ensure the fridge system is running 100% 

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!

Case Study of Chiller Service

On a site in Northampton, a chiller looked like it was short of gas, but to a discerning eye it needed service- the EEV had failed. The mechanical part of the Electronic Expansion Valve had jammed up causing the chiller to trip out. A relatively easy job as it was just a straight swap. The chiller was pumped down and valved off. The EEV driver was okay. The valve clamped 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

Evaporator Freeze-Up

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!
