Andrews provide a modern alternative to aged R22 cooling system

The introduction of the Ozone Regulation in 2009 paved the way for a gradual shift away from air conditioning units that use refrigerant gas and other ozone depleting substances. This has since led to a widespread need for replacement systems to be sourced as businesses strive to comply with legislation.

So when one of our major clients based in central London decided to upgrade its cooling equipment to a more environmentally-friendly substitute, they approached us regarding a solution. At the same time, our customer’s premises were undergoing a renovation which involved being taken back to its original design – an open plan layout.

One option was to maximise flexibility via the controls strategy in case the office was to be subdivided by tenants in the near future. This was the preferred choice of the facilities manager and meant the air conditioning arrangement we installed was split into two parts – providing a 50% contingency and ensuring that even in the unlikely event of breakdown, the building would not be left without any cooling capacity.

Individual ‘shut off’ valves were installed on the distribution box to enable singular shutdown of either fan coil whenever necessary. This facility guarantees minimal disruption but excellent versatility should things change on site at any point.

Despite its simplicity, this type of connection is fairly unique yet often completely overlooked by other companies operating in our industry. Interestingly, the cost of implementing this service was minimal in balance with the overall project, which was completed to the total satisfaction of the premises owner.
