Case Study of Chiller Maintenance

We currently provide chiller maintenance, 3 visits a year on 4 air cooled chillers at a secure site. Our customer signed up to the 3 year contract as soon as the projects company had completed. They were eager to get us on board from the start as our reputation precedes us in the industry: to extend the life of chillers. He was pleased with our smart, helpful engineer who went though the usual teething and adjustments of commissioning. These Included:

Tightening the Wiring

The commissioning is the most important day of the chiller's life. Tightening the wiring today will ensure an easier time in the future


Air trapped in the water system was causing issues to the plant. We identified where the problem was occurring and made component adjustments to ensure the problem went away


These can become blocked on first start up as debris from the project is carried round to the strainer. We found a spanner but they were otherwise clean


The evaporator was adjusted to give the correct pressure. We then worked out the COP (coefficient of performance) to be 4.2 a good read back 

100% Load

Our engineer then built up some load and ran the chillers in anger for half an hour. The superheat and subcooling values were within operating limits with a clear sight glass. The oil return and compressor temperatures were good
