Food Rethermalizer Requirements
NSF Standard 4 requires, for products manufactured for the purpose of rethermalizing food, that the food reach a safe serving temperature of 165°F in two hours or less in order to be listed to the NSF4 standard. The Hubbell model JFR is designed specifically for food rethermalizing, but only in conjunction with a hot water bath rethermalizer. Hubbell supplies neither the vessel nor the system that determines how food is placed and held in the vessel. The Hubbell JFR only supplies hot water to the vessel. Each vessel must pass its own NSF performance requirements and although Hubbell provides sizing recommendations to help correctly size the JFR to the vessel, there are many variables involved in the manufacturing of the vessel that impact its ability to pass the NSF requirements. The Hubbell JFR is ETL and ETL Sanitation (ANSI NSF 4) listed for construction only. It is the responsibility of the manufacturer of the vessel to have the complete rethermalizing product tested and listed to the NSF 4 Standard once the JFR is installed onto the vessel.
