Introduction de produit

The heat-pipe energy recovery unit extends individually charged copper circuits through two finned sections located in adjacent supply and exhaust ducts. Working fluid evaporates in the warmer half, travels through each sealed circuit and condenses in the cooler half before returning. An integral metal partition is expanded and sealed around every tube penetration so the two duct sections remain physically divided. Circuit geometry can be arranged for side-by-side horizontal air paths or one stream above the other, with the charge and return path selected for equal seasonal recovery or a preferred heating or cooling duty.

Key Features

Loop-circuit geometry can provide balanced seasonal recovery or favor the selected heating or cooling operating condition.

Copper tube penetrations are mechanically expanded into the integral divider to preserve separation between the two air paths.

Selections up to eight tube rows and multiple aluminum or copper fin densities match available face area and pressure-drop limits.

Accessible fin faces, protective coating options and a dedicated drain section simplify cleaning and wet-side maintenance.

Préoccupations du client produit

Heat-pipe recovery depends on the physical relationship between the two ducts, even airflow across the finned faces and suitable drainage and frost protection at the cold section.

Supply and exhaust ducts are often stacked vertically rather than aligned side by side.The divided module can be configured for adjacent horizontal paths or an over-under arrangement with a circuit layout suited to the installed orientation.

High face velocity creates excessive pressure drop and leaves the downstream fan with insufficient reserve.The coil face width, height, row count and fin spacing are selected together to keep velocity and resistance within the ventilation duty.

Wet exhaust deposits and corrosive residue reduce heat transfer at the leading fin edges.Wider fin spacing, accessible faces and an application-compatible fin coating preserve cleanable surface area in demanding exhaust service.

Condensate or frost restricts the cold fin section during low outdoor-temperature operation.A correctly sloped drain pan combined with bypass or preheat control keeps liquid and ice from progressively blocking the face.
