Wacker Neuson’s HDR 155 Directs Clean, Dry Heat

Delivering 155,000 BTU/hour (45 kW) heat input, the HDR 155 easily heats workspaces, workers and objects such as equipment, concrete form work and other structures from approximately 15 ft. (5 m) away.

The Wacker Neuson HDR 155 direct-fired radiant heater features a heating design unaffected by the elements, so the heat is easily directed exactly to where it's needed, according to the manufacturer.

Delivering 155,000 BTU/hour (45 kW) heat input, the HDR 155 easily heats workspaces, workers and objects such as equipment, concrete form work and other structures from approximately 15 ft. (5 m) 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 direct-fired HDR 155 heater uses an oil flame to heat its stainless steel disc to approximately 1,700 F (926.7 C). The shield emits electromagnetic (infrared) waves that travel in straight lines away from the heater, unaffected by wind or weather, to warm objects they hit. Exhaust gases are directed upward, so the heat is clean, dry and healthy. The heater's 300-series stainless steel front panel delivers performance and extreme reliability and longevity.

The design of 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, according to the manufacturer.


“Molded refractory is used to slow the movement of heat, but the rear surface of a heater using molded refractory still gets extremely hot after less than one hour of operation,” said David Mencel, Climate Technology product manager of Wacker Neuson. “Conversely, the Wacker Neuson air-cooled design keeps the rear of the HDR 155 significantly cooler than other radiant heaters on the market. In addition, ours is a low-maintenance cooling system, whereas molded refractory eventually cracks and must be replaced, which costs the owner hundreds of dollars in maintenance.”

The new construction-grade Wacker Neuson HDR 155 direct-fired radiant heater boasts many rental- and user-friendly features that lower operating costs and provide many years of reliable service. Large pneumatic tires, single point lift bail and tie-downs provide easy loading and transport. Its retractable floor guard eliminates the need for floor mats or other protection, while a two-position, 10-degree adjustable housing offers precise control over heat direction. The heater's rugged, rotomolded 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 job site.

Because of its rugged design, the HDR 155 can be used in a variety of heating applications, including construction sites, warehouses, dairy, sports arenas, aircraft/hangar heating and thawing, mining and oil services, highway maintenance, and concrete curing.
