OAB Instant Dry Steam Generator. Choose from saturated, 300°C, 500°C, 800°C to 1000°C Steam. Vary the temperature and steam rate on touchscreen displays. Indicate maximum back pressure. Set safety triggers—clean, instant, dry, high-quality Steam.

A 100- 500 kg/h instant steam generator for 24/7 industrial use
Users save energy and enjoy improved efficiencies (greater than 98%
) with no CO2 emissions. On-off, high-temperature, and adjustable steam parameters enable process optimization via the touchscreen or remote adjustment (via Ethernet) of the temperature and steam flow rate settings. Steam production is almost instantaneous after a backfill. No requirements for additional blow-down machines make the OAB steam generators much lower in equipment, energy efficiency, and operational costs than comparable-sized boilers. The external controls of temperature, humidity, and other parameters via the PLC make the systems customizable for specific user applications.
Request a quotation. We will need to know the steam flow rate range (kg/h), temperature output range, and the system back pressure.
Features:
- Electric-powered operation eliminates fossil fuel use and greenhouse gas emissions.
- Precise temperature and pressure control for enhanced process efficiency and accuracy.
- Compact design and modular configurations for flexible installation and easy scalability.
- Advanced safety features and compliance with industry standards.
- Simple to use. Easy to install all. It saves energy and improves process productivity. Meets the requirement for deep decarbonization.
Programmable steam temperature, high-quality, adjustable rate, continuous superheated steam production. Easy incorporation of process triggers via Ethernet—touchscreen controls—rapid returns on decarbonized equipment.
- Save substantially on electric costs.
- Choose models up to tons /hr. Choose output temperature—Request Quote.
- OAB® units offer unique full-back pressure capability as required. On-off at ill. Steam temperature is achieved within minutes. No idling is necessary. Advanced PLC and HMI controls. Ethernet-enabled.
- Steam on-demand, high-quality 100% clean steam, and low condensation contribute significantly to the high steam-making efficie
ncy. For steam generators, instant Steam-on-demand is enabled with electricity on/off without storing Steam (energy) in a vessel. - Choose models up to 200°C, 300°C, 800°C, or 1000°C and higher. Set the temperature and flow on the touchscreen HMI. Please discuss.
- Electric steam generators, such as MightySteam® and OAB®, do not produce greenhouse gases like CO2, Methane, or NOx—only Steam.
- Innovative and Modern: There is no need to specify high pressure when the requirement is for high-temperature Steam. Specify a pressure requirement only to overcome the back pressure in a process.
- Modern communication protocols for external/remote management (such as setting the temperature, setting the flow rate, or creating event triggers) are safety features for remote operations.
- Modern leveling features.
- Avoid costly ancillary operations and equipment associated with traditional boilers.
Choose from single-phase 4 -12 Kg/hr to three-phase 40-3000Kg/hr variable steam rate.
Save on electric costs by using on-demand power for the required low. Steam generation is almost instantaneous.
The steam generator draws water from the tank and converts it to Steam. The Steam discharges quickly through a standard pipe. The flow and temperature can be varied with the control panel. This innovative technology has been designed to provide high-quality Steam in a highly efficient and reliable manner.
- OAB® units offer independent control of steam temperature and flow rate. They now offer variable-flow models for the 1–3000 kg/hr steam range. Control features are provided to give the user broad flexibility to optimize processes and energy use.
- For steady-flow units with a standard selection of flow rate and temperature variability, please specify the OAB® model from the table below.
- Instant Steam. Compact units for tons/h.
- For 440 kg/h, 750 kg/h, and 10,000 kg/h, please get in touch with MHI.

- Use for chemical processes, steam drying, antibacterial, plastics cleaning, dry-cleaning, and much more. Please specify steam quantity (kg/h, required steam temperature, and backpressure rating. The backpressure rating will determine the shell rating requirements.
- Easy Connectors and Steam Tube Extenders.
- The adjacent pictures show an easy-to-attach K-type clamp connector, the OAB-12 300, and the Extender Vittori Tube.
- The OAB-4 has steam side valve options for regulating the Steam.
- The OAB models offer steam flow regulation with electronic logic controls.
