INTRODUCTION
The atco Mini Display Warmer is designed to hold prepared
foods for prolonged periods of time while maintaining that “just-
made” quality. Mini Display Warmer cabinets provide the best
environment for products like sandwiches, cookies, pretzels,
muffins, and desserts by regulating the air temperature.
The Mini Display Warmer air flow pattern is designed to
maintain consistent cabinet temperature. The heat sources
create a “blanket” effect around the food. The air flow rate
enables the cabinet to rapidly recover temperature after
opening and closing the door. Configurable access doors and
magnetic adjustable shelves make the atco Mini Display
Warmer perfect for any food service application.
atco Mini Display Warmers are products of extensive research
and field testing. The materials used were selected for
maximum durability, attractive appearance, and optimum
performance. Every unit is inspected and tested thoroughly
prior to shipment.
