Client: Roberts Bakery Requirement: Effective Evaporative Cooling System Solution: Breezair Industrial Cooling System

When it came to finding an answer to excessively high temperatures at its Cheshire bakery, Frank Roberts & Sons turned to CoSaf Environments to provide it with an effective industrial cooling system.

CoSaf specified the Breezair Evaporative Air Cooling System from Seeley International (Europe), which has been installed to provide effective spot cooling throughout the bakery including the mixing, production, slicing, packaging and despatch areas.

One of the largest and oldest independent bakeries in the UK, Roberts Bakery produces over two million bakery products weekly for retail, catering and food service customers throughout the UK and Europe. Prior to the Breezair system being installed, its premises in Northwich, Cheshire used general ventilation, which was introduced into the bakery via outside air ducting and fans. As this system relied on outside temperatures being between 12 and 14C, when these rose to over 20C, the air being introduced was far less beneficial.

CoSaf Environments conducted an in depth survey of the bakery to ascertain the best method of improving overall thermal comfort. The company observed that the high roof collected heat, which acted as a huge blanket under which all the heat from the ovens and bakery products collected causing the temperature of the entire space to rise so that the temperatures within the building exceeded the ambient temperature of 21C by between10 and 16C, depending on the location of the temperature reading.

“Refrigerative air conditioning, apart from being prohibitively expensive, was unsuitable for this application as hot air from the ovens and gas fired equipment would have been circulated around the bakery”, said Bob Sullivan, Director, CoSaf Environments. “By installing a Breezair cooling system we were able to utilise the existing extraction system whilst at the same time introducing cooled, fresh air into the building”

To kick off the project Cosaf initially installed four Breezair coolers into the Morning Goods Production Area. The coolers were installed outside the building, with air being distributed via aluminium ductwork to air diffusers and then into the production area to provide temperature relief. Such was the success of this initial installation, with temperatures dropping by around 6C below outside ambient temperature, that Chris Daniels, Chief Engineer at Roberts Bakery decided to install a further 24 coolers throughout key areas within the bakery.

“The Breezair system has drastically reduced working temperatures”, says Chris Daniels. “The introduction of cooled, clean fresh air has benefited both the bakery and our personnel who are enjoying a more comfortable and healthier working environment.”
