Hot Plates and High Heat Flux Radiators

Electric Hot Plates

Choice 9″x 9″, 18″x 18″.  Standard Power or Very High Power.

Temperatures up to 1500°C. TLID options.

Thermoplate™ and Thermotables™ are Hot-Plates with surface temperatures above 600°C, 1000C, 1200C, and  1400°C (Thermotable). The TLID is available for all models.

High Heat Flux Thermpoplate™ models with grill tops allow direct radiation heating depending on spacing. The grill-top material may be used up to 1700°C.

  • 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.
  • The top can be partially open (grill or hole top) or fully open(“open top” mode)l for direct coverage with high heat flux.
  •  Contact us.
  • Choice of Tops for Thermoplates and High heat-flux Thermoplates and Thermotables.
  • Surface heating devices offer radiator temperatures from 1300°C to 1850°C.
  • 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 “x18” 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.

1700°C-1800°C [High Heat Flux Power Radiator Only]- Element temperature. The grill top available is up to 1700C.Hot Plate

A grill top may be used with a Thermoplate (4KW, 16KW Radiator) or a Thermotable (14KW radiator).

Contact MHI for the new SuperPower ThermoTable™ Models. In the 9″ x 9″ or 18 “x 18” size, the options are:

  1. A ThermoPlate with power 4KW or 16KW and a  solid top.
  2. A ThermoGrill with power  4KW and an open grill-top. The bottom of the grill sees radiation up to 1700°C+. The heating elements operate at 1400°C or 1850°C. The spacing between the grill rods can be adjusted.

Each Thermoplate has a uniform electronic temperature/power controller and transformer. A picture of a Thermoplate is shown below. The height is almost ~5.”

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.
