Create a deeper holding area with Glo-Ray® Aluminum
Dual Infrared Foodwarmers with two heaters mounted
side-by-side, keeping hot food at optimum serving
temperatures. The pre-focused heat pattern directs
heat from a metal sheathed element across the entire
holding surface. The continuous aluminum housing and
heavy-duty mountings ensure the durability and quality
of Hatcoproducts.

Standard features

• Provides even heat distribution – no “cold spots”

• Pre-focused heat maintains safe serving temperatures longer

• Sturdy extruded aluminum housings that do not sag, from
18" to 144" (457 to 3658 mm)

• Reector does not blacken, maintaining a consistent
heat pattern

• Reinforced wire guards provide operator safety without affecting
heat distribution

• 3" or 6" (76 or 152 mm) spacer available as a center section
between two 6" (152 mm) heater sections for a deeper
holding area

• Heavy-duty insulation minimizes heatloss

• Optional sneeze guard made of shatterproof, easy-to-clean

acrylic provide safe food serving environment

• Additional reector styles and lower wattage elements also

available, please consult factory for more information

• Metal sheathed heating element part guaranteed against
burnout and breakage for two years
