Transforming Steam Technology For Significant Energy and Water Savings. Savings efficiencies reported are from On to Off condition. No requirement to heat any tubes or nozzles to produce steam. Conventional boilers are never 100% dry. The old conventional boilers’ heat loss causes steam to condense and become wet as it travels down the steam line. A decrease in steam dryness hinders heat transfer; it is, therefore, important to monitor steam dryness to provide optimum heating efficiency for your system. The OAB® steam is very dry.

Comparing OAB® instant (within minutes) steam-generators to others:
- High-quality high-temperature steam is made within a minute. When not required, the unit can be switched off. There is no idling required. Good steam generators provide instant on/off capabilities which saves energy. The system cools down quickly as there are no chambers or pipes to cool off.
- A temperature above the inversion temperature without the need for high pressure leads to energy efficiency and a reduced amount of steam wastage.
- Low condensation.
- The controls include phase-angle SCRs, soft start, and other modern features that enhance the element life. The controls include PLC and HMI.
- The energy efficiency from cold water to steam estimate is ~95%. Many companies may claim this, but on a closer examination of the numbers, one may find that the base for the energy estimation could be pre-boiled water, one that ignores the long start-up cycle time. The correct energy efficiency compares socket-power to steam-power with base energy of room temperature water converted to steam. Low condensation leads to improved efficiency
- The unit uses 50/60Hz. OAB® steam Generators do not use high frequencies like the induction frequencies that can disrupt modern plants.
- ASME Section V111 Div 1 and other ratings are offered.
- OABs provide full control of steam temperature, steam rate, and pressure in an independent fashion. This is not old boiler technology. It is the modern instant steam technology. Are you having to use special equipment for blow down?
- Some competitors use generators for pipe heating which then heats the fluid. Such technologies translate to heating thick high-pressure pipes with external heat. Such systems are energy inefficient and could also be the source of pie-ruptures at high temperatures.
- The OAB offers a low number of external connectors compared to other steam generation methods. Just one connector to the user’s pipe is required for the OAB.
- The back-pressure rating will determine the shell rating requirements. This feature allows for money savings if backpressure is not required. Steam generators do not need to generate high pressure for high-temperature steam.
- The OAB has a compact footprint and is therefore easily locatable at the point of use.
- Easy Connectors. The units provided are completely operational – there is no need for the user to purchase additional parts to operate the units.
- Steam quality is very high—no water droplets.
- The most important feature of a steam generator is that it is a continuous process and can run for short or long durations.
- The system is designed with sustainability goals in mind. Because steam production is instant – within a minute, one does not have to plan a shutdown or start-up outside working hours. The water input is continuous but only when required for operation. Unlike Boilers and their modern cousins – no special chambers are used for boiling. This gives plant-wide operational flexibility and offers high energy efficiency.

MHI’s One Atmosphere Boiler superheated steam boiler features patented InstaSteam™ technology, allowing for rapid startup times, unparalleled efficiencies, and up to 1300°C temperatures. BoilerFree™ technology allows most OAB® units to be installed without needing traditional boiler certifications. The OAB® is ideal for use as an industrial steam generator, for de-wrinkling operations, superheated steam drying, and dozens of other specific applications requiring a high-efficiency boiler that does not require boiler certifications. So many great uses in packaging, textiles, drying, and more.
Highly Scalable.
Compare Efficiency. Three types of efficiencies are essential to consider. (1) the efficiency of the steam generation device where the OAB® and MightySteam® excel; (2) the efficiency of the downstream process that the steam is used for; and (3) the overall water usage efficiency and propensity to recycle the water. The one-atmosphere steam-gas generator/boiler performs well in all three categories.
Controls: Modern controls with logic PLSC and touch screen HMIs are used for the industrial models.
Plug N Play – The OAB® devices are very user-friendly for installation.

Plug-n-Play, Easy Piping and Connectors
Easy to attach pipes or superchargers (economizers). Uniquely configured K type clamp connectors make it easy to attach the steam pipe to any chamber or device. Easy to split the steam direction.
How does one increase the production rate for drying and other steam applications?
Short Answer: Increase the temperature of the process gas or steam and use a high-efficiency steam generator for high-quality energy.
Long Answer: Please click through to the Steam Calculator page.
Better conversion allow the OAB® units to use fewer resources to produce more steam. A standard OAB® steam output at 300°C, is obtained almost at the theoretical efficiency of power conversion. The OAB’s rapid start-up (generally with a minute from a cold start) also adds considerably to the overall lowering of energy usage. No moisture is noted even at start-up.

Getting to temperature quickly and faster results in lower operational wear and related costs i.e. an overall higher productivity with
corresponding higher kinetics. The output velocity of the 550°C OAB® steam is very high – almost 40m/s or more. This feature is used for the uniform heating of kettles/heat exchangers and for reaching large piping distances without significant loss of temperature. For industrial vats and kettles, the heating rate makes a considerable difference to the overall process economics. A general rule of thumb of productivity from traditional pressure boilers is – (0.35 Gallons of a heated product like water)/kWhr. For the OAB-4® it is closer to – (1 Gallon/kWhr) i.e. almost three times (numbers may be lower or higher as they are situationally dependent and one needs to evaluate on a case by case basis). Industries served for during. Please also see Single Phase OAB and Airtorch®.
The OAB® offers a scalable design and because of the small foot-print qualifies for the MHI Never-Down policy. The scalable design allows
the user to choose what fraction of the boiler needs to be turned on on a given day or hour and changed at will. MHI electronics provide
full data logging, on-screen data acquisition display, and a repertoire of 100 programs – all in the small sophisticated control panel.
