ELECTRICAL RATING CHART – FR2 MODELS
* Based upon NEC 2002 Code
† Based upon THHN wire rated 90ºC.
NOTE: NSF Standard 4 has recently added performance requirements for food rethermalizing. The requirements mirror
the requirements for food rethermalizing in the FDA Food Code. The basic requirement is that food reach a temperature
of 165°F (74°C) in a time period of two hours or less.
Appliances that are manufactured for the purpose of rethermalizing food will need to meet these performance
requirements in order to be listed to NSF Standard 4.
The Hatco FR2 Series heating unit is specifically made for food rethermalizing, however, the heating unit is designed
to be incorporated into a hot water bath rethermalizer. Hatco does not supply the vessel that contains the water,
nor the system which determines how food is placed and held in the vessel. The Hatco FR2 unit attaches to the bottom
of the vessel and supplies hot water to the vessel.
Hatco does supply sizing recommendations to enable the appliance manufacturer to correctly size the FR2 unit
to the vessel. However, there are variables in the way that the vessel is manufactured that affect its ability to pass
the NSF performance requirements. The Hatco FR2 unit is listed with NSF for construction only. Due to the fact that
the FR2 is only a portion of a larger system, it is impossible to do performance testing until the FR2 unit is incorporated
onto the water vessel.
The result is that it is the responsibility of the vessel manufacturer to have the entire rethermalizing appliance tested
and listed in accordance with NSF Standard 4. Simply hanging an NSF listed FR2 unit on the appliance does
not transfer NSF listing to the entire appliance.
