Evaporative Cooling in the Data CentrePremier foods was looking for a cost effective bakery cooling strategy for their Barnsley site.  Evaporative cooling can guarantee cool supply air of below 25°C all year round in the UK, making it the perfect solution for those wanting to reduce temperatures in their bakeries. 12 down discharge EcoCoolers were supplied and fitted to 12 existing Air Handling Units (AHU’s) on the roof of Manor Bakeries, Barnsley to provide cooling for the bakery. The existing refrigeration based cooling system has been decommissioned and the packaging area and the area is now solely cooled using the EcoCooling Evaporative cooling system.

Each EcoCooler can provide up to 40kW of cooling for an electrical input of only 1.2KW, saving both money and carbon emissions.

Following commissioning the system was tested and monitored, the following performance figures were recorded for the facility:

External Ambient = 23°C (warm sunny clear day)

Air temp off cooler = 16.6°C

Air volume through cooler = 4.47m3/s

Present Cooling capacity = 34KW per cooler

Total System capacity = 12 coolers x 34KW = 408 KW

Due to the modular nature of the design, it can be expanded as the internal equipment within the area increases, easily coping with any increased heat emissions. Evaporative cooling is extremely beneficial in a bakery environment. The humidity levels keep the bread fresh and don’t dry it out, unlike traditional air conditioning which is extremely dry and can often shorten the lifecycle of fresh produce, so it is highly effective for bakery cooling.
