High Temperature Furnace Models
Furnaces for High Quality Industrial/Production Use. Please inquire about the MHI Neverdown™ feature.
All sizes. Large industrial sizes to small. Furnace 1700°C/1760°C/1800°C with MP class heating-elements or 1400°C Models with GAXP class heating-elements. High-uniformity high-temperature furnaces from MHI. Specialty furnaces include high power density and large span models – features that the novel heaters and MHI insulation ceramics allow in the construction.
Comparing furnaces? What guarantees do you have for long life furnace. Here are a few…
- Is the warranty on Electronics at least 2 Years.
- Is the warranty on Heating Elements at least 1 Year
- Is your furnace made with all stainless steel for long life. Inside and outside?
- Safety refractory without fibers used as appropriate including for the doors.
- Top mounted MHI Moly-silicide heating elements. Best Life.
- High quality roof hangers?
- Is the exterior wall cooled for safety?
- Lab Scale Furnaces

Dross reduction Attachments to Furnaces e.g. Aluminum
- Reduced Energy Costs – Energy efficiencies of 0.2 kWhr/lb for melting with no emissions.
- Improved melting from ultra clean metal.
- Clean melting, with dross values less than 0.5% depending on configuration.
- No requirement for nitrogen, argon, or chemical fluxes – significantly reducing operating costs and the environmental impact.
- Extremely small equipment footprint as shown above in Figure 1.
- Quiet operation – Zero noise -much lower than typical, conventional plasma systems.
- High energy density nearly four times compared to the standardAnd..
Steam Ovens
Add Steam to a MHI Furnace or Oven MHI makes it easy for steam inlet port. New furnace prices have been dramatically reduced so that a steam inlet port and steam generator may be ordered with the furnace.
- MHI High Intensity Offerings
- So many choices based on our years of understanding your specific needs
- Furnace Safety
- Data Acquisition for MHI Furnaces – MHI-DACS
- Unique easy connect features. Easy disconnect for tube furnaces.
- Easy connect terminals for better energy management and cooler terminals
- Unmatched high alumina roof hanger designs. Do not settle for a furnace without roof hangers.
- Muti-tap transformers.
- Uniformity: High order of +/- 2°C temperature uniformity
- MHI innovates for powerful concentrator technology. Our power concentrator furnace shown below has the highest energy density in its size class. PC furnaces have very high power concentration (J/s/m3) in order to enable a concentrated power processing of materials.
- Your Choice. Concentrate Hot Air, Concentrate Hot-Steam or Hot Electrons or Hot-Ions
- Call MHI at 513-772-0404 for more information.The fastest way for heat delivery is now with enhanced convection + radiation + e-Ion heavy assist.
- High Intensity for Aluminum Furnaces to Save Energy and Dross.
