Installation and Operation of IRHU

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 prole is preset at the factory. This reduces

the likelihood of inconsistent performance between restaurant locations.
