St James University Hospital

We were called to a Cancer research analysis facility in Leeds to investigate and remedy an issue with one of their large cold rooms. This is a vital piece of equipment. To ensure site had as little down time as possible our engineer attended the same morning

Condenser feet replacement

In attendance to carry out an FGas Check on the Glycol Systems at Hoylake Lights Wetherspoons we noticed that one of the condensers was playing a balancing act, sat on bricks precariously over a puddle thanks to the lovely British weather!


Most frequent questions and answers

Not really, no. Refrigeration gas is pretty much odourless, but it is possible to detect a faint smell if you have a very sensitive nose. If you can smell it, then it’s a slightly sweet chemical odour in or around your fridge. In the unlikely event you smell that, there’s a slight possibility that your refrigerator is leaking its refrigerant.

Sadly, no. Lots of people think Refrigeration kills bacteria but it actually just slows their growth, prolonging the life of your produce. You should frequently and regularly wash your refrigerator so that the bacteria can’t build up over time. Commercial premises typically have a cleaning schedule that they follow religiously in accordance with HSE stipulations.

The compressor runs for between 80% and 90% of the time in order for refrigerators and freezers to maintain the proper temperature. This is normal healthy functioning – refrigerators and freezers have compressors that are designed to run 80% to 90% of the time.

A quick check of the equipment is your first port of call. Diagnose the simple stuff first. It might sound obvious, but make sure that the fridge is plugged in and that the RCD (trip switch) hasn’t switched off the power. If the fridge is switched on and getting power but still not cooling properly, vacuum the coils under or behind the fridge. Clogged coils can cause inadequate cooling. Check to make sure nothing is stuck in the condenser fan and that it spins freely (models with coils on the back won’t have a fan). If none of that works then it maybe time to call out STS-UK to look at the unit, to see if repair is economically possible.

Refrigerators work by causing the refrigerant circulating inside them to change from a liquid into a gas. This process, called evaporation, cools the surrounding area and produces the desired effect. … When you release the contents into the lower pressure open space, it turns from a liquid to a gas.
