Breezair evaporative colling system for Frank Roberts bakery

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 evaporative cooling system.

CoSaf specified the Breezair evaporative 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.

Evaporative cooling system better than general ventilation

Prior to the Breezair system being installed, its premises in 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.

Breezair the solution

“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 Breezair evaporative cooling systems 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. 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.”

Ultra-modern design

The Breezair system is housed in a simple, clean, ultra-modern designed plastic casing specially developed to withstand all weather conditions. The Breezair's state-of-the-art components include an innovative water distribution system, which delivers continuous, balanced water coverage to all the pads. The world-patented system ensures maximum cooling efficiency and minimal maintenance problems.

An innovatively designed, aerodynamic fan provides a constant, even flow of air over the pads to provide a welcome cool breeze with minimal noise and low energy consumption. Other pioneering components include a highly efficient water pump that guarantees constant and reliable cooling when most needed, and a long lasting variable speed motor that gives maximum comfort level control.
