MANUFACTURER'S INTRODUCTION

The Model MM1 Heat Station 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. This unit is equipped with an accessory 120 volt receptacle at the back which is fused for a maximum of 5 amperes. It may be used for powering a timer. This receptacle is furnished only on Model MM1. The MM1C Heat Station is equipped with an infinite switch to control the temperature on the ThermoGlo™.
