Outdoor Wood Boiler Hot Water to Air Heat Exchanger Coil

Outdoor Wood Boiler Hot Water to Air Heat Exchanger Coil 1.Main material: Aluminum pipe (O.D8 to 0.D10) x (t0.7 to t1.0) (tube inner smooth or inner grooved) Copper pipe: (O.D6 to O.C9.52) x (t0.36 to 0.5 tube inner smooth or inner grooved)   2.Structure: Draw expanded type Insert type Side embedded type Machine expanded type Spiral finned type   3.Technical ability: Fin specification for A type (L x W): 60 x 27mm, 77 x 27mm Hole distance: 25mm Fin specification for B type: width 50 or 60mm, holes array as the 11 x 19.05 (22 equilateral trangle shape) Fin specification for D type: O.D9.52 copper tube Hole distance 25 x 25mm (square shape) Fin pitch: 4.2mm   4.Performance: Surface anodic oxidiztion or dip coating to prevent the corrosion Note: the inner grooved copper tube increases the heat exchange area and enhances the heat exchange performance Jaslant insert type and spiral evaporator comparatively has the largest heat exchange area and enhances the heat exchange performance .
