RINNAI CONTINUOUS FLOW HOT WATER SYSTEM SPECIFIED IN FOOD MANUFACTURE PLANT A Rinnai continuous flow hot water solution has been installed at a large-scale seafood processing and manufacturing plant on the North East coast. The system was installed by H Pickup & Sons having used Rinnai products for several years on major projects. H Pickup Mechanical & Electrical Services Limited were established over 100 years ago and are based in Scarborough, North Yorkshire. The company offer a comprehensive range of mechanical & electrical services direct to their clients: Electrical Building Services; Mechanical Building Services; Planned & Reactive Maintenance; Gas Servicing; Heating and Plumbing Services; Electrical & Mechanical Design & Installation Services and Contract Management. “We employ our own staff engineers both on site and in contract management in order to enable us to deliver unprecedented service and ongoing support to our customers”, says Mike Joy for Pickups. The food manufacture site had an old stored hot water system which was no longer able to cope with the demand for the high volume and high temperature hot water needed for cleaning down production areas as the site increased its production lines, as it expanded its market ordering and product range. The site was also looking to substantially increase energy, fuel cost efficiency and reliability by removing the stored hot water. “There were long periods of time with no requirements for hot water, then sudden high demand as production areas need deep cleaning. Running out of hot water would result in substandard cleaning, especially the removal of grease, and industrial cleaning products used to clean many of the surfaces. Another deciding factor for the site - Rinnai’s ability to resist Legionella breeding which is a risk with a “lukewarm” hot water system. With Rinnai continuous flow units water temperature for distribution is accurate to ±1˚C. The fact that there is no stratification as there is no storage, ensures a continuous, permanent even temperature. There is no requirement to heat a volume of water just to ensure the elimination of Legionella bacteria as the minimum temperature that a continuous flow unit achieves is in excess of advisory levels.
