Hot-Plates & Glow-Panel Radiators

Thermoplate™ are Hot-Plates above 600°C.

  • Thermoplate™ products and HeatPads™ are rated by the temperature and surface area.
  • Glow-Panels™ are rated by the device power, radiation area and the radiating temperature.

Thermoplate™ and Glow-Panels™

One year warranty on heating elements/heaters on select Thermoplate™ – Hot Plate Models.

Thermoplates™ offer High Life, High Warranty, High Power, High Temperature, High Heat-up Rate with large Hot-plate size availability.   MHI models are specially constructed for use with the optional guided TLID (t/c  included in select TLID models).  The control panel provided with the Thermoplates may be used to set a precise temperature or a profile with read and control functions for versatile process programming.  The MHI-DACS may be used to plot or download the data – with remote monitoring capabilities.

What is a TLID? It is an insulated lid with about 1.5” of space from plate to roof.  Has a t/c as shown in the picture below.  For large loads it provides a guided way of maintaining temporal symmetry in thermal profiles i.e. repeat ability is enhanced.   User- preferred product.   The TLID provides an integrated guided mechanism for quick insertion with ergonomic handles.

MHI offers a variety of specialized surface and radiative heaters.
