Manufacturer of tunnel conveyor pasteurizer required several efficient and responsive instantaneous heaters for their 9-zone conveyor to pasteurize pickles.
Water is recirculated through each zone in the pasteurizer and sprayed on the jars of pickles. However, each zone must be operated at a different temperature so as not to shock the glass jar. Therefore, each zone required a separate heater to maintain the circulation water temperature. Accurate water temperature was paramount.
