Hotsy’s HeatMizer Series provides reliable radiant heat directly without moving air

The HeatMizer Series is Hotsy’s line of portable radiant heaters with clean combustion and 99.9% efficiency. Using diesel #1, diesel #2, kerosene or jet fuel, the HeatMizers innovation lies in the elimination of the refractory material cone that surrounds the combustion chamber on competitive heaters. The direct heat flow radiates instead of blowing air, so there’s no air movement.

The HeatMizer features a metallic forced air insulation pocket between the combustion chamber and the external protection cone. The cooling air is blown through the pocket by the burner fan, which overcomes the fragility and brittleness of ceramic cones. This keeps the frame cool to the touch.

Hotsy’s RedHot Cannon portable forced-air heaters provide indirect heating where you need it

The RedHot Cannon Series is Hotsy’s line of portable forced-air indirect heaters. Using diesel #1, diesel #2, kerosene or jet fuel, the RedHot Cannon can be ducted to provide clean, dry healthy heat for outdoor events and residential or commercial construction sites.

Diesel indirect-fired portable heaters use an embedded burner with combustion air obtained from the main ventilation fan. The RedHot Cannon heaters feature a four-pass heat exchanger that contains the flame and expels fumes through a chimney connected to the outside. This technology allows exhaust gases to increase heat exchange with the cooling air and obtain maximum thermal efficiency.
