The Most Modern Steam Generator and Boiler Technologies.  The Units Offer Independent Control of Temperature, Pressure and Steam Output.

Click to Steam Products Home Page.

Typical model numbers shown below. If a pressure rating is not required please inquire about MHGA models.

MHI provides UL/ CE rated controllers.

Pressure vessel third party rating is offered (e.g. Section V111. Div. 1). Electric Panel Ratings UL, cUL and CE.

The minimum temperature is 200°C.  Pressure and flow rate are independent settings.  ASME PV ratings are provided when requested.  The control panel can be CE or UL or with cUL ratings. Flow rate can be varied from about 30% to full amount of the  specific model.

Should your back pressure be less than 4 Bar and you require variable flow, please consider the models OAB-100-Var and OAB-50-Var.

Modern HMI panels for touch screen interface for operator ease.

On Demand Steam: GHGA™ and MHGA™, choice of models.

GHGAwhen the back pressure expected is more than 2Barg.  MHGAwhen it is less.  Please specify in the RFQ.

From 3Kg/hr to 200 Kg/hr Scalable Super-heated Steam Platform.

Control the flow and temperature independently with flow and power controllers.  Independent pressure control.

Visit this page particularly if:

  • You are looking for high efficiency on-demand high temperature steam generators
  • You are looking for independent control over temperature, flow rate and pressure
  • You are considering changing from a large combustion boiler to a clean steam generator including discrete generators for every station
  • If you are planning new fuel and CO2 conversion or related technologies
  • if you have to optimize steam chemical reactions for syngas.
  • When dedicated to sustainability and efficiency with steam generators.
  • If you prefer to decouple pressure and temperature in your steam output.
  • When very high temperature say 400°C, 800°C,  1300°C steam is critical for use.
  • GHGA – Scalable Platform  Models/Features.  Set the flow, temperature and pressure independently. Set flow on a touch screen HMI.
  • More MHI Steam Generator Models, Plasma Steam Models and Steam Chambers.
  • The OAB® and GHGA™ steam generator systems will change the way you think of super-heated steam in regards to installation, safety, size, fuel-production,  and operational costs. 
  • Please contact MHI for details, information request or quotes.
  • Extremely easy operations for  settings.
  • On-off steam.
  • For fine tuning pilot process development for quick scale up to production.

Typical and frequently asked questions:

Q: I  need a variable steam rate generator at a maximum temperature of 400°C to 800°C.  Can I use your steam generator GHGA models ?  Ans:  Yes, the GHGA models are the correct choice for variable flow and variable temperature requests.    The price will also depend on the pressure vessel rating and range of variable (adjustable) steam flow. Typically we are asked for 3-6 Kg variable or 4-12 Kg variable steam at the high temperature with unit-adjustable back pressure.

Q: Can you provide a shell of 40 Bar. Ans: Yes we can provide ASME Section V111, Div 1 standards with external rating.

Q: Can I get a touch screen HMI control panel.  A: Yes of course, this is our standard on some models.

Q: I have a 49 KW boiler, can I use your steam generator instead?  Ans: Yes: The closest fit is the GHGA-36-(PV) or the OAb-50.  Unlike boilers the steam generator units can be on off at will.  No idling required.  The temperature out-put of the steam will be between 150C and 800C depending on the model, flow settings and power settings.   The GHGA-36-(PV) unit will produce 36 Kg/hr steam at the maximum temperature.  The OAB-50 unit will produce 50 Kg/hr steam at the maximum temperature The price will depend on the pressure required and other selected features.  The lowest priced systems are when the steam flow rate is fixed.

Q: Do steam generators work differently than boilers? Ans. Yes steam generators work in a different manner compared to pressure boilers (1) they are instant on-off, no idling required (2)  in a clever way the pressure will only build to the maximum line requirement in order to improve the efficiency (3) temperatures can be set for very high temperature with high quality dry steam, and (4) they can be easily matched to other line or cross line pressure flows.  Saves energy.  Adds to the world sustainability index. Allows for new reactions and higher productivity options to be explored.

Q: I have a 200 Bar steam line that feeds the entire industrial testing plant, can I use discrete 40 Bar steam GHGA units from you?  Ans:  Yes the savings are enormous and chances are that you will also be converting from a coal, oil or gas fired boiler to a clean electric unit.  On-off at will.  Use units at discrete locations.  No dangerously long piping at high pressure and no idling.

Q: Antimicrobial steam? Yes, please contact MHI for data on antimicrobial or sterilization quality steam. Visit the steam application page.

GHGA-12 Robust

GHGA Instant Versatile Steam Generators

Versatile instant steam generator with independent control of temperature, flow and pressure functions.

Q: Are your Panels UL, cUL or CE rated.

A:  Yes one can order with any of these ratings.






Q:  What are your typical pressure vessel standards.

A:  Please contact MHI.  Our typical standards are ASME Section VIII Div I.

The steam generator foot print is likely to be considerably lower than a tradition boiler with the same output steam.

Pricing Advice:  The price increases with temperature requirement, capacity of the steam generator, pressure requirement and other special requests.
