The HDR 155 Direct-Fired Radiant Heater features a heating design unaffected by the elements, so heat is directed exactly to where it's needed. Delivering what product engineers contend is best-in-class, 155,000 Btu/hour heat input, the HDR 155 easily heats workspaces, workers and objects such as equipment, concrete form work and other structures from approximately 15 feet away. Since infrared heat radiates directly from the heater's disc, the HDR 155 does not rely on warming the surrounding air like convection heating, so it produces quick, intense heat.
The HDR 155 boasts three concentric cones: the inner cone containing the flame; center cone that protects the outermost surface from heat; and external cone constructed of high-temperature-painted carbon steel. The air stream is split between the inner cone to support the flame and center cone to provide cooling air for the heater's surface. This "refractory free" cooling system results in a significantly cooler heater surface that does not require the expense or maintenance of molded heat refractory panels.
The model also features large pneumatic tires; single point lift bail and tie-downs; retractable floor guard; and, 10-degree adjustable housing offers precise control over heat direction. The heater's rugged, roto-molded plastic fuel tank provides enough capacity for a 15-hour continuous run time, and an optional remote thermostat gives operators control over the temperature at the jobsite.--Wacker Neuson, 800/770-0957; www. wackemeuson.com
