BullEx’s unique Smart Class A Fire Technology features dual combustion technology to create fire using both gas and wood. Smart Class A technology was developed to allow firefighters to utilize real burning wood in their training scenarios without worrying about the environmental effects.

Our Smart Class A technology is a two part system that allows instructors to burn class A material and subsequently clean the smoke and hydrocarbon filled air. After an evolution has finished, smoke is captured in a chamber through ventilation and is burned a second time with propane gas, resulting in air that is 99.5% clean at the end. This technology allows organizations to meet clean air requirements while conducting effective and highly repeatable training.

The dual-fuel burner is capable of igniting up to 100 lbs. of class A material using propane or natural gas. This system allows trainees to completely extinguish the fire and reignite it almost immediately for countless evolutions, decreasing downtime and maximizing training.

For firefighters, heat and smoke are the real enemies. To be properly prepared to face these challenges, training with wood-fueled fire is critical.  Burning wood gives off real heat and heavy smoke that most realistically simulates an actual fire incident.  Smart Class A fire technology by BullEx is the perfect solution for instructors looking to provide realistic yet environmentally friendly training evolutions.

The Smart Class A system includes a specially designed Class A chamber with a built-in gas ignition module that an instructor can operate from a distance. The instructor uses the gas module to ignite the wood in the chamber. Once the fire has been extinguished, it can be lit again immediately – without having to load more wood into the burner. Although the wood remains wet after being extinguished, the gas flames and unique chamber design quickly dry and reignite the wood for the next training session.

To address the emission issues of traditional Class A burning (black-smoke), smoke and gas is drawn from the structure and burned a second time with propane gas. The after-burning process takes away and purifies the smoke before releasing it safely outside the training room as clean-air emissions.


Built-in water suppression systems and smart controls keep firefighters safe, even in the toughest training conditions. When the E-Stop is pressed the Class A fire is extinguished and the smoke is cleared automatically for safer training. The fire prop is equipped with a water-drench system and is supplied with a high-volume water line for rapid fire suppression. The ventilation automatically adjusts to 100% capacity to quickly clear the smoke.


BullEx training structures and centers provide hands-on training solutions for any high risk industry. Smart Class A technology can be used to achieve a wide variety of training objectives. Offer your trainees the opportunity to get hands-on experience with complete Class A material burns. Contact BullEx with your training objective and we’ll work with you every step of the way to custom craft a solution.

Hands-on training is the most effective method of learning when it comes to confronting dangerous fire emergencies. Smart Class A fire technology accurately recreates fire behavior in repeatable evolutions, allowing trainees to get the experience that comes with full extinguishment of Smart Class A materials.

BullEx is capable of supplying all the necessary training tools and structures for your structural fire departments.  Add realism and repeatability to your structural firefighter training with BullEx Smart Class A technology. Smart Class A is a great resource for training both new and advanced firefighters on initial fire attack, ventilation, water supply, hose stream application, and other tenets of structural fire training.

Smart Class A fire technology can be included as part of your new construction or built into an existing training facility. Smart Class A technology can be built as part of training towers, complexes, or in training containers.


BullEx is the world leader in designing, engineering and building large scale multi-disciplinary training complexes.  Our Training Complexes often combine a range of fire technologies that apply to the full range of training disciplines. In addition to traditional propane-based props, Smart Class A can round out your training complex by allowing firefighters to experience repeatable evolutions with real wood fires.



BullEx fire training facilities include multi-story training towers, fixed petro-chemical structures and a wide range of other buildings that are ideal for interior and exterior fire training.  Adding Smart Class A fire technology to your training facility can add realism to fire behavior, backdraft and flashover fire training.


BullEx Training Containers and Roll-offs are a great solution for departments with large-scale training needs and limited space. Containers are portable, but offer all of the training capabilities that a fixed space provides. Training containers outfitted with Smart Class A technology and an afterburner are a great way for organizations with limited training space and environmental burn restrictions to conduct live-fire training anywhere.
