Test Equipment

To carry out an effective visit, it is vital to have test equipment reading correctly. Fluke multimeters, insulation testers, digital thermometers with 'k' type thermocouples are provided to our engineers. Calibrated HFC refrigerant gauges are also provided. NH3 personal alarms are carried when working with ammonia. Wrong readings lead to confusion and misdiagnosis

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 chilled water systems. 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 chillers life. Tightening the wiring today will ensure an easier time in the future


The air bleed valve on the buffer vessel was found to be closed tight. It should be loose to let the air out. Opening this sorted out the problem


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

Evaporator Curve

The evaporator was adjusted to give the correct ΔP (difference in 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 ΔT (difference in temperature) was good. The superheat and subcooling values were within operating limits with a clear sight glass. The oil return and compressor temperatures were good
