Refood’s anaerobic digestion plant in Widnes includes 12 FHE-250 modular hot water boilers supplied by heat transfer specialist Fulton.
Shane Murray, group project manager for Saria, Refood’s parent company, said: “Fulton presented a solution to provide multiple small hot water boilers which, additionally, gave us spare capacity during scheduled maintenance or if one of the boilers malfunctioned.”
The installation has two primary functions: to provide hot water for the site cleaning and hot water for washing and sterilisation of the food waste bins. The boiler system also provides heat to the pasteurisers prior to the anaerobic digesters.
Heat from the boiler system is also used for the underfloor heating system in the offices and ancillary processes.
Murray added: “We were so impressed with the design, installation and the fact that heat and hot water from Fulton’s boilers are used for so many functions that we are also discussing maintenance packages with the company.”
The boilers feature a fully condensing, stainless steel heat exchanger. Their modularity means that additional boilers can be combined to suit any application and hot water requirement.
