Designed for high efficiency direct-fired airheating with high turndown and low emissions. Suited to once-through systems

where air for combustion is a portion of the process air flow in the duct. Features:-

• modular sections which can be combined into straight, H , T or X sections.
• wide process air velocities tolerated.
• high turndown , up to 30:1
• gas manifolds available in cast iron or aluminium
• common burner head or natural gas or propane gas.
