2-Stage Heaters Automatically Power Down At Peak Comfort Levels


Solaronics 2-stage Infra-red Heaters — True Dual low intensity and Sun Twin high intensity — shrink operating costs by  40% to 75% while improving comfort and air quality  in commercial, industrial and agricultural buildings. Fueled by economical natural gas or widely available LP gas (Propane) and requiring no periodic maintenance, the energy-efficient heaters radiate infra-red energy to warm people, floors and work surfaces, providing high comfort levels with safe, quiet and reliable operation in new construction or retrofits to existing buildings such as manufacturing plants; auto repair / body shops; fire stations; farm buildings; warehouses; car washes; maintenance facilities; aircraft hangars; sports arenas.         

Operating in high-heat mode when the facility is cool, the heaters automatically power down to the energy-saving low-heat setting when the preselected building temperature is reached. In most buildings the heaters will be at low-heat setting about 90% of the time, keeping energy costs in check. What distinguishes the patented Solaronics 2-Stage systems is the precise matching of air to gasratios at both high- and low-fire stages for optimum combustion efficiency 100% of the time. Excessive overheating is prevented and a softer, more stable and comfortable environment is maintained.  Solaronics True Dual 2-Stage Low Intensity Tubular Heaters are available with input ratings from85,000/65,000 BTUH (high-heat / low-heat) to 200,000/145,000 BTUH for both Natural Gas and LPgas. The burner is fully assembled and factory tested, ready to hang. Heavy duty 12 gauge heatexchanger is standard, as well as direct spark electronic ignition. Simple chain mounting provides easyinstallation. Brite finish aluminum reflectors can be angled to direct the heat where needed.         

Solaronics SunTwin 2-Stage High Intensity Heaters provide instant heat on demand, reaching maximum operating temperature within one minute. Input ratings are 100,000/50,000 BTUH (high-heat/ low-heat) to 200,000/100,000 BTUH for Natural Gas; 90,000/45,000  to 160,000/80,000 BTUH  for LP gas. Factory prewired, prepiped and tested, with seamless no-weld construction and rugged corrosion-free aluminized steel main frame. Individual SunTwin heaters may be utilized for spot heating or in multiples to heat entire buildings.
