True Dual Two-Stage Gas Infra-Red Tube Heaters provide precise air to gas ratios at both the high and low heat stages for optimum efficiency. Excessive overheating is prevented and a softer, more stable and comfortable environment is maintained. Saves up to 75% in energy costs, and typically 10-15% savings over a single stage tube heater.
Solaronics gas fired infra-red 2-Stage True Dual Suntube systems are ideal for any commercial or industrial building. Inlet air capabilities make them particularly well adapted for buildings with high negative pressure or airborne contaminants such as dust, over-spray and degreasing fumes. Directly vented units are an ideal choice for buildings with low infiltration or where condensation is a problem. Although not explosion proof, True Dual Suntube has no open flame.
Solaronics gas fired infra-red True Dual Suntube systems are available in many different input capacities, system lengths and configurations. True Dual heaters offers six capacities: 85/65, 100/65, 125/95, 150/100, 175/125, 200/145 BTUH. These ranges are available in 20′ through 70’ tube lengths, at 5’ increments. System lengths available in both straight and compact U-tube configurations. True Dual Suntube is CSA International Designed Certified to ANSI/CGA Standards for either directly or indirectly vented operation and for use with inside or outside combustion air.
