MANUFACTURER'S INTRODUCTION

This Heated Display Cabinet features Marshall's own ThermoGlo" heating technology. Heat radiates from every square inch of the upper flat plate heating surface. This eliminates the need to clean intricate calrod, wire and reflector assemblies. A precision microprocessor-type digital display and digital "set point" temperature controller maintain consistent product temperatures.
