Building Heating Options

FF Series™—The FireFox™ system provides the most efficient method of replacing process exhaust with fresh air and solves building pressure problems.

D Series™—The Dragon™ system provides a low air volume system that reduces the amount of outside air required to heat a building with a direct-fired heater. Most effective as a larger space heater located on the roof, above dock doors.

PR Series™—The 80/20 PR™ system utilizes positive pressure and recirculation to eliminate cold spots in the space due to building infiltration. Make-up air volume increases as doors open, maintaining positive pressure on the space.

AR Series™—The Air Rotation® System high volume, low velocity, continuous circulation of air distributes heat more evenly and efficiently than any other system. Air Rotation® solves big building condensation problems or concerns and also substantially reduces operating cost.

PA Series™—“Pure Air” indirect-fired gas-fired make-up air units provides up to 100% outside air without any products of combustion in the building.
MarCraft® Custom Air Handling - The MarCraft® custom air handling unit combines special materials of construction, special or unique geometry, special filtration and many other custom features to meet each of the customer’s needs.
