Uniformity
High Heat Flux Thermpoplate™ models with grill tops allow direct radiation heating depending on spacing. The several top materials may be used up to 1700°C. MHI specializes in high-temperature materials.
- Thermoplate™ and High Heat Flux Themoplates are wide-area high-temperature products rated by temperature and surface area.
- The rating of a surface heating device is based on 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.
- Several sizes and distortion-free high-temperature use
- The top can be engineered for direct coverage with high heat flux.

- Plate tops and high heat flux grill tops to 1700°C.
Hot Plate uniformity depends on the coverage. With the TLID (optional), the uniformity is within ±2°C on the Plate for even the 18 “x 18” models (customer report).
Ordering High Heat Flux Thermoplates and Thermotables
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.

Thermoplate™, Thermotable™, and Glow-Panels™
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.
