Manufacturer’s Introduction 

The Duke Product Holding Cabinet was developed 
in  response  to  need  for  extended  food-holding 
capabilities  to  provide  consistently  high,  “just 
cooked” food quality. 

The  Duke  Product  Holding  Cabinet  utilizes  Duke’s 
patented  “heat  sink”  holding  technology  that 
provides  even  heat  distribution  to  food  pans 
through  the  bottom  and  sides.    This  allows  pre-
cooked  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  Product  Holding 
Cabinet eliminate food odor and taste transfer.   
Because the compartments are sealed and formed 
to the shape of the pan, no disassembly is required 
for cleaning and product changes. 

The  unique  design  of  the  Duke  Product  Holding 
Cabinet  allows  single  temperature  operation  for  all 
existing  product  groups.    This  190°  F  approved 
temperature  is  preset  at  the  factory.    This  reduces 
the likelihood of inconsistent performance between 
locations.  

The  Duke  Product  Holding  Cabinet  was  also 
designed  to  rethermalize  food  product.    A 
thermostat  setting  of  200°  F  minimum  is  required 
for rethermalization.  See instructions on page 6 for 
thermostat  adjustment.   

NOTE:  Only  qualified 

service 

persons 

should 

modify 

control 

temperature presets.
