Welcome to the cost saving convenience
of Low Temperature Cooking.
In 1968, Alto-Shaam invented the first
automatic, commercial cook and hold oven 
featuring the principle of Halo Heat. The 
heating method provided by Halo Heat low 
temperature cooking and holding ovens 
consists of an electric thermal cable that 
encircles the entire cooking and holding 
chamber. This creates a gentle blanket or 
HALO of radiant heat — surrounding food 
with a consistent and uniform temperature 
with no air movement inside the oven 
compartment. This gentle heating concept 
cooks at low temperatures and at a high 
level of humidity to preserve product 
moisture, flavor, and nutrition. Halo Heat 
ovens are designed to convert automatically 
from a cooking temperature to a holding 
temperature where the product can remain 
until it is ready to be served.
Halo Heat is an entirely different system
of cooking. Utilizing this uniform heat 
source, Halo Heat dramatically reduces 
meat shrinkage; provides natural enzyme
(aging) action for more tender, flavorful 
meat; and preserves natural juices along 
with nutritional values in all foods. Halo 
Heat cooking reduces energy cost, cuts back 
on labor and handling, and solves kitchen 
space problems. There is no mechanical 
ventilation or oven hood necessary in most 
areas so the ovens can be moved wherever 
they are needed.
Read this booklet carefully. Halo Heat
is a cooking system that requires minimal 
care once you have learned the basic 
principles. For best results with many 
products, we recommend you start your 
cooking cycle the evening before — for 
serving the next day. In many areas, off-
peak power rates are also lower at night.
If anything you cook in a Halo Heat
low temperature cooking and holding 
oven doesn’t meet your highest standards 
of quality, please contact one of our food 
service professionals for help. Usually, only 
a minor change in procedure is required.
