SIU Series - For commercial/industrial use only

The Economical Alternative for Hard-to-Heat Spaces

Designed for demanding commercial and industrial applications, this U-shaped infrared tube heater series delivers powerful, energy-efficient comfort in warehouses, garages, service bays, loading docks, and other hard-to-heat spaces. By using radiant heat instead of moving large volumes of air, these gas infrared heaters warm people, floors, and equipment directly, reducing stratification and helping cut operating costs.

• Reliable pull-through system for consistent burner performance and tube temperatures
• Multiple Btu outputs and tube lengths to match a wide range of building sizes and layouts
• CSA design certified for trusted safety and performance
• Available for both natural gas and propane applications
• Flexible venting options: sidewall or through-the-roof
• Vented or indirect vented operation to suit installation requirements
• Optional elbows, corner reflectors, and decorative grille for improved coverage and appearance
• Includes 36″ stainless steel gas connector for a clean, durable hookup

The U-shaped emitter tube and high-efficiency reflector system help project heat evenly across the floor area, making this series ideal for spot heating, zoned heating, or full-building coverage. Recommended minimum mounting heights, clearances to combustibles, and gas/electrical supply requirements ensure safe, code-compliant installations in commercial and industrial environments.
