Veloci’s Fire 155 Heater is a revolutionary Radiant Mobile heater that stands in a class of its own as the largest in the world. The innovation of the Italian Fire 155 Infrared Heater lies in the elimination of the refractory material cone that surrounds the conical combustion chamber which is typical of competitors’ units. The Fire 155 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 and pushed into the environment being heated. This method of heating, effectively serves as a hybrid style of heating through the use radiant and forced air heat. This innovative technology over-comes the well known problem of fragility within the cone of competitors’ models while providing a safer unit when in operation due to the air insulated cone.

Places you will see the Fire 155 might include Commercial Construction Sites, Residential Construction Sites, City Infrastructure remodels, temporary Space Heating, Curing Concrete, Agriculture Temp Heat, Water Restoration, Drying Drywall/Paint, Rental Tent Heating, and many, many others. The Fire 155 has proven itself in a multitude of industries across four continents where it is present in Construction, Public events, and Agriculture to ensure that work never stops. The value of working through inclement conditions in comfort far out weighs the cost of these units as they last for many years with their Italian patented design.

Why Infrared Heating?

Great question! There are three major forms of heating to consider when purchasing a Mobile Heater:

Radiant Heating, also known as Infrared, operates on the concept of Heat Transfer as compared to Heat Exchange (blowing heaters). Veloci’s Fire and Flame heaters are Radiant mobile units manufactured in Italy. These heaters have an internal burner that heats up an external face plate to 1400°F which transfers heat to any objects in front of it in a conical shape. Radiant units should technically not be used as space heaters since they do not heat air and, instead, heat objects. However, the Veloci Fire and Flame heaters have an air pocket that requires forced air. This unique technology yields a hybrid heater that effectively heats space and objects simultaneously. While the forced air output is only approximately 250 CFM, circulating air from heated objects, including the heater’s face, is the most efficient practice when fast heat is needed.

Forced Air Indirect-Fired Heating is essentially a mobile furnace. Veloci’s Blaze line is an Indirect Forced Air heater manufactured in Italy. These units have a separate internal chamber where combustion by-product is isolated and expelled through a chimney which means that the hot air forced from the outlet is 100% clean heated air. Veloci’s Blaze heaters also have a patented 4-Chamber design that captures more heat for the forced air to exchange. This, in-turn, requires a larger fan which allows for an increased output of Cubic Feet of air per Minute (CFM). Compare the Blaze series CFM to any box store heater’s CFM and you will see Blaze units move clean heat at an exponentially higher rate. There is no use in having a high BTU unit if you cannot effectively move the heat into the desired environment.

Forced Air Direct-Fired Heating has 100% efficiency but typically emits 30-40 PPM of Carbon Monoxide into the environment being heated. Direct-Fired heaters are the cheap ones typically found at hardware and big box stores. They quickly cause watery eyes, scratchy eyes, headaches and fatigue as the occupants of the environment are inhaling exhaust fumes. Furthermore, these units can leave an exhaust smell and purple haze when in a closed environment such as completing drywall or paint projects. Direct-Fired heaters should never be used in a closed environment or for livestock since the repercussions can be catastrophic. This is true for any Direct-Fired heater whether its fuel is Diesel or N/LP.
