FR FOOD RETHERMALIZERS / BAIN-MARIE HEATERS
Models FR-3, FR-4, FR-6, FR-9, FR-3B, FR-4B, FR-6B, FR-9B
The Hatco FR is designed to be used
with a Bain-Marie or food reconstitutor,
to heat or hold foods at safe temperatures
between 140 F and 190 F (60 -88 C).
FLEXIBILITY
The FR mounts easily to the underside
of a holding vessel, leaving the entire
vessel area free. Water is continually
circulated to avoid any “cool” spots.
The unit controls water temperature
from 140 F (60 C) to 190 F (88 C).
The Hatco FR is shipped factory
assembled, pre-wired, and includes
standard 2" (51 mm) plated brass
plumbing fittings for mounting into
a holding tank. A full-size template is
supplied to properly locate fitting holes.
QUALITY
The following features assure the finest
performance for years to come:
• Every Hatco FR is equipped with an
ECO (Energy Cut-Off) wired into the
electrical circuit. This built-in protection
“breaks” the power to the elements if
the temperature of the water goes
above the normal thermostat setting.
• FR models feature a stainless steel
tank with a five-year limited warranty.
• An optional low-water cut-off is
available to prevent element burn-out
due to a low water condition.
• The Hatco FR has separate sump
and heating compartment drains for
cleaning and sanitizing. 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 water heater(s). Water containing over 3.0 GPG
(.75 GPL) will decrease the efficiency and reduce the operating life
of the unit.
Note: P oduct failu e caused by liming o sediment buildup is not
cove ed unde wa anty.
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.
Hatco sells a heating unit 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 FR 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
FR 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 FR unit is listed with NSF for
construction only. Due to the fact that the FR is only a portion of a larger system, it is impossible to do
performance testing until the FR 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 FR unit
on the appliance does not transfer NSF listing to the entire appliance.

VOLTAGE
208 or 240 volts, 50/60 Hz, standard. 480 volts and export

PRODUCT SPECS
Food R constitutor/Bain-Mari H at r
The electric heater designed to hold foods in the bain-marie
or heat and hold frozen foods in a food reconstitutor shall be
a Hatco Model .... as manufactured by the Hatco Corporation,
Milwaukee, WI 53234 U.S.A.
With 24/7 service (U.S. and Canada only), the Hatco Model FR
shall be rated at ....kW, ....volts, ....phase. The heater shall be
complete with all internal plumbing and wiring ready for external
installation to the bottom of the
holding vessel.
The heater tank shall be of stainless steel construction and
dual reservoir design; one reservoir to contain a permanently
submerged heating element, the other to trap and collect soil
which can be emptied easily by a convenient drain.
The heater shall be equipped with an external thermostat
adjustment calibrated from 140 F to 190 F (60 to 88 C) to
control the water temperatures and an overtemperature device
to protect the unit from overheating. There shall also be an
indicator light to signal when water is up to temperature and
another to indicate power is on.
The heater shall consist of stainless steel front and silver-gray
hammertone body (or stainless steel body and base).
★Open delta on 3-phase. Larger circuit required than for balanced 3-phase
of equal kW.
†Balanced 3-phase.
