FR2 Hydro-Heater Food
Rethermalizers / Bain-Marie
Heaters

Models: FR2-3, -4, -6, -9,
FR2-3B, -4B, -6B, -9B

The patented Hatco FR2 Hydro-Heater Food
Rethermalizers / Bain-Marie Heaters are designed to
supply temperature-controlled water to a sink mounted
above the heater. Utilizing "free-ow" technology
to ensure a responsive and efcient operation, the
FR2 models can heat or hold foods at safe-serving
temperatures between 140°F (60°C) to 190°F (88°C).

Standard features

• An electronic controller with digital display maintains an
accurate setpoint temperature

• Features a tubular water chamber with a spiral heating element
wrapped outside the ow tube so elements do not come in
direct contact with the water

• Unit includes a stainless steel front, powdercoated body,
low-water cut-off system, convenient drain outlet and
clean-out caps

FOOD RETHERMALIZING REQUIREMENTS

NSF Standard 4 has 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 reaches 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 Hydro-Heater is specifically made to be used 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 simply 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 UL Classified on NSF 4 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.

SIZING INFORMATION

For a Bain-Marie or Steam Table: MINIMUM 750 WATTS PER
SQUARE FOOT (0.8 WATTS PER SQUARE CM) of vessel top.

For a Food Rethermalizer: MINIMUM 2000 WATTS PER
SQUARE FOOT (2.2 WATTS PER SQUARE CM) of vessel top.

Use one FR2 for a Bain-Marie up to 6' (1829 mm) long. Over
6', minimum two required.

MUST BE INSTALLED WITH A PERFORATED WATER
BAFFLE. This baffle is not supplied with heater. The FR2
should be positioned with no more than 3’ (914 mm) on
either side when mounted in holding vessel. Consult factory
or installation manual for fabricating details.

WATER QUALITY REQUIREMENTS

Incoming water in excess of 3.0 grains of hardness per gallon (GPG) (.75 grains of
hardness per liter) must be treated and softened before being supplied to hot water
dispenser(s). Water containing over 3.0 GPG (.75 GPL) will decrease efciency and
reduce the operating life of the unit.

Note: Product failure caused by liming or sediment buildup is not covered

under warranty.
