Manufacturer’s Introduction
The Duke IR Holding Unit was developed in
response to the need for extended food-holding
capabilities to provide consistently high, “just
cooked” food quality.
The Duke IR Holding Unit utilizes Duke’s
patented “Infra Red” holding technology that
provides even heat distribution to food pans.
This allows fried foods to be held for extended
periods without noticeable degradation of quality,
reducing food scrap/waste.
The self contained, individually formed, sealed
compartments of the Duke IR Holding Unit
eliminate food odor and taste transfer. Because
the compartments are sealed, no disassembly is
required for cleaning and product changes.
The unique design of the Duke IR Holding Unit
allows the IR energy to be programmed for each
compartment. The holding profile is preset at the
factory. This reduces the likelihood of
inconsistent performance between restaurant
locations.
