Features- Models available for vertical or horizontal configurations.
- Heavy wall cast housing in 356 T6 aluminum, carbon steel or 316 stainless steel.
- Net free area through banks three to four times the unit pipe size, resulting in increased flow capacity with minimal pressure drop.
- Bank’s large surface area improves heat dissipation.
- Removable cover plate and extensible bank assembly for easy inspection, cleaning or replacement.
- Unitized housing does not require support for proper bank alignment during maintenance.
- ‘Off-set’ housing design ensures flow capacity unaffected by condensate accumulation, even when installed in horizontal piping.
