Description
Schwank 40 FT 155,000/110,000 BTU 2-Stage Outdoor Patio Tube Heater | duraSchwank SPW2 | SPW2-155-40-AN
The Schwank SPW2-155-40-AN is a duraSchwank SPW2 gas-fired, low-intensity infrared tube heater rated at 155,000 high / 110,000 low BTU/h on natural gas, with a 40 ft straight radiant tube. Instead of heating the air, an infrared tube heater sends radiant energy down to the floor, equipment and people below, much like the sun. Those surfaces warm up and release heat back into the space, so the area at working level stays comfortable even in tall buildings where warm air would otherwise collect at the ceiling, and heat recovers quickly after overhead doors open.
Built for wet, damp and outdoor-exposed locations such as patios, wash bays and open-sided buildings, this is a two-stage heater: it runs on low fire for mild weather and steps up to high fire when the load increases, which smooths out temperature swings and saves fuel compared with a single-stage burner cycling on and off. The burner housing is powder-coated and the tube and reflector are aluminized steel.
Where It Works Best
- Warehouses, distribution centers and manufacturing plants
- Auto repair shops, garages and fire stations
- Loading docks and areas with frequent overhead door openings
- Aircraft hangars, arenas and other high-ceiling buildings
