Furnace Controls
MHI offers three control options with our tube furnaces: Electronic control panels with overtemperature controls, MHI DACS as an electronic controls program, and SIMGAS4 as a gas management system. The combination of these controls makes MHI tube furnaces highly robust and scalable.
| MHI Furnace Controls | |
| Many of MHI’s electronic furnace controllers feature multiple voltage inputs, overtemperature controls, programmable cycles, and several other features. For more information about MHI’s control panels, Contact Us or See More Information. |  |
|
|
| MHI Data Acquisition and Control Software (MHI DACS) | |
| MHI Tube Furnaces are compatible with MHI DACS for furnace controls, step programming, data logging, and more. DACS also allows for remote furnace control, allowing one central location to control multiple devices. |  MHI DACS Software |
|
|
| MHI SIMGAS4 Gas Mixing System | |
| Gas Management Systems in tube furnaces serve the materials and electronic community when processing has to be carried out in vacuum or gas atmospheres. You can expect excellent temperature uniformity with MHI tube furnaces. We can also provide you with a complete custom gas control panel with gas lines and controls. |  SIMGAS4 and Rotary Tube Furnace |

Tube Furnace Applications
Because of their versatility, MHI’s furnaces allow for several uses.
Because each application is unique, Please Contact MHI to discuss which product best fits your needs.
MHI high temperature furnaces incorporate industry tested control systems. Tube furnaces find use where an accurate temperature or temperature gradient is required with an atmosphere. Tube furnace applications. Several models are listed below. Typical options that are routinely quoted are the gas management systems (SIMGAS), oxygen and other gas sensors, vacuum and vacuum measurement systems. Use for sintering, brazing, metals, ceramics, optoelectronics, biomaterials, composites and intermetallics.
MHI’s single and multi-zone tube furnaces are available in temperatures up to 1760°C for all applications where process heat is required. Standard dimensions for single phase heated tube zone of 2.5″ x 12″ three zone high uniformity are 27″. Several laboratory and industrial models available with quick disconnects. Long uniform zone. A typical configuration is shown on the right with multiple gas inlets. Available also are customized end-caps or quick-disconnects (snap screw or buckle snap). Everything is listed in the quote for choosing options including a low price data acquisition and process download option. How uniform are the MHI tube furnaces? A testimonial from the Stanford HUTF facilities. See also uniformity page. “The high-uniformity tube furnace facility provides the ideal environment for quantitative measurements of absorption spectra and spectral parameters (line strength, line-broadening coefficients,and more). It is also provides controlled conditions for sensor validations“.
