MAX OX™ 900 Boiler (900K Btu) is a modern commercial size device for burning of readily available small chunks of waste wood, wood chips, wood briquettes, shavings, sawdust and bark.
The MAX OX™ is an alternative fuel heating solution engineered for the highest levels of efficiency and automation. It burns a wide variety wood based fuels and is available as a boiler or hot air furnace. The MAX OX is equipped with sensors and microprocessors monitoring and automating the high-tech operation. In addition to this cutting edge technology, the MAX OX is built on rock solid construction. MAX OX is pioneering the way to combining technology, quality and biomass combustion.
MAX OX is proudly made in the U.S.A.
MAX OX Wood chip gasification boiler - a closer look
The control panel contains all of the electronic controls for the MAX OX boiler. The onboard PLC (Programmable Logic Controller) with 6" touch screen automates the control of all feed cycles and output processes, while monitoring temperatures through out the unit, freeing the operator from any operating assistance during changing load demands, changing fuel moistures or auger jams. An Oxygen sensor on the exhaust path signals back to the control panel where the information is processed against current temperatures and burn settings to maximizes combustion efficiency. The feed auger, induced draft fan, and circulator pump are all variable motor driven components controlled to ramp up and ramp down as load sensors dictate. This process smoothes the burn cycles creating very tight control of operating temperatures. The control panel of the MAX OX is programmed to monitor and fully protect against boiler over-temp, heat demand overload, auger jam and self corrects to maintain operation.
The wood chip gasifier
Fuel is pushed up from the center hole via the modulating feed auger. The circular grate allows for air to easily reach the constantly agitated fuel, thus maximizing burn. As fuel is burnt, ash falls to the floor of the burn chamber and is cycled out with the ash removal auger.
Fuel feed system
The MAX OX feed system incorporates fundamentally basic elements to keep operation simple, yet is engineered for continuous flawless operation. The modulated 10 amp motor drives an 8 inch auger capable of easily handling 1.5 inch wood briquettes. In the rare event of an auger jam the proximity sensor on the toothed wheel times out therefore causing the auger to reverse and then forward to automatically clear the auger. This procedure will repeat up to 3 times in order to clear the auger jam, after which an alarm will signal for operator intervention. Alarms from the control panel can be configured for beeping, signal light and remote computer alert.
Sensor monitored feed auger
The fuel gate opens to except fuel coming from the conveyor system and closes moments after the cycle stops. The fuel gate provides safety as well as minimizes the risk of foreign material entering the fuel input area of the MAX OX. The door is equip with a pneumatic piston connected to an on-board off the shelf air compressor, thus eliminating the need for customer supplied compressed air. A sensor provides the control panel with the gate's status.
Hot Water Boiler
As fuel is being burnt in the gasifier, the super heated exhaust is transferred into the boiler section. The boiler is where all the heat exchange takes place. The boiler is water-cooled, water filled, and water-jacketed. Factory configuration is setup to use the boiler as an open system with an expansion tank. Closed system operation can be configured.
Heat exchange tubes
The hot air exhaust, after it has cycled through the boiler, will pass through the cyclone to filter out any remaining particulate and finally exit via the chimney as a smokeless exhaust.

Industrial | Commercial size biomass boilers
The MAX OX boiler Btu output can reach 900K Btu. If you are looking to build and heat greenhouse structures or poultry housing or need an industrial alternative for heating with sawdust, the MAX OX wood chip gasifier boilers achieve great economic savings. While biomass fuel is readily available, it is important to research the kind of fuel most common in your area. There are promising tests being performed to verify that the MAX OX can burn other types of fuel making it even more flexible. Contact Total Energy Solutions to see what fuel options are in your area. Make plans to store additional fuel onsite to allow for any drying that is needed as well as to avoid fuel shortages.
