HYDRO-HEATER FOOD RETHERMALIZERS / BAIN-MARIE HEATERS

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

The Hatco Hydro-Heater is a state-of­the-art, high efficiency circulation water
heater, using a combination of “free-flow”
technology and advanced electronic
controls for circulating hot water by
natural convection in a sink for
reconstituting frozen foods.

This heater features a tubular water
chamber with heating elements uniquely
wrapped outside the flow tube so
elements do not come in direct contact
with the water. The design reduces
sediment and lime buildup on the
element, resulting in longer life. A special
electronic controller maintains the
setpoint temperature assuring
a responsive and efficient operation.

FLEXIBILITY

As a food reconstitutor, the Hydro­Heater FR2 heats or holds food at safe
temperatures between 140°F and 190°F
(60°-88°C).

QUALITY

The following features assure the finest
performance for years to come:

• Utilizes “free-flow” technology and
advanced electronic controls to assure
a responsive and efficient operation.

• All models include a stainless steel
front, powdercoated body, convenient
drain outlet, and clean-out caps.

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: Product failure caused by liming or sediment buildup is not

covered under warranty.

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 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 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.
