Hot Plates and High Heat Flux Radiators
Thermoplate™ and Thermotables™ are Hot-Plates with surface temperatures above 600°C (up to 1700°C) on the top.
High Heat Flux Thermpoplate™ models with grill tops allow direct radiation heating depending on spacing.
- Thermoplate™ and High Heat Flux Themoplates are wide area high-temperature products rated by the temperature and surface area.
- The rating of a surface heating device is by the device power, heat flux, radiation area, type of top, and the radiating temperature, which can be as high as 1850°C.
- The heating is with an optimized coverage heater.
- The top can be partially-open (grill or hole top) or even a fully open “open top” model for direct coverage with high heat flux.
To discuss the unit that is best for your application.- Choice of Tops for Thermoplates – Covered Plate, Hole Top, Grill Top. Top temperatures from 1000°C.
- Surface heating devices offer radiator temperatures from 1300°C to 1850°C.
- Plate tops and high heat flux grill tops to 1700°C.

What is a TLID™? It is an insulated lid-chamber with about 1.5” of uniform chamber space from the horizontal plate to the TLID- roof. Chambers inside the TLID contain a thermocouple integrated with them. The lid chambers provide a canopy for large loads with exceptional temperature uniformity. The TLID chamber has an integrated guided mechanism for quick and safe lid insertion. There is no standard Lid for the Glow Panel (GP models); however, MHI can offer custom swivel closing hinged devices (like a door) for the GP models.

Compared with other commercial Hot Plates. MHI offers a one-year warranty on heating elements/heaters on select Thermoplate™ – Hot Plate Models.
Thermoplates™ offers High Life, High Warranty, High Power, High Temperature, High Heat-up Rate, and large Hot-plate size availability. Thermoplates are similar to hot plates – used in a horizontal condition. MHI hot plate and glow panel models are specially constructed with thermal shock-resistant materials. Most models offer the optional guided TLID chamber (t/c included in select TLID models). The temperature and power control panel provided with the Thermoplates may be used to set a precise temperature or a profile – read and control functions are included for versatile process programming. The Ethernet system for data acquisition may be used to plot, save or download the data, i.e., remote monitoring capabilities.
