Heat Exchanger Cores

Heat exchanger coreXchanger heat exchanger fin-tube cores can be installed in ductwork as original or replace existing units to heat and cool low pressure gas streams.  Use our interactive online form to get a fast and accurate quote!

Common Applications
Cooling, dehumidifying, and heating low pressure air/gas systems.

Fin-Tube Core
The fins are rectangular plates with a matrix of die-extruded tube collars.  A sheet metal casing provides rigidity to the fin-tube assembly prior to tube expansion.  After assembly, the tubes are expanded into the fin collars.  This allows for a gap-free connection maximizing heat exchanger performance and structural integrity.

Installation Considerations
The fluid circuit consists of several parallel tube circuits, which are joined at inlet and outlet headers.  The circuits are designed to work “down hill” to prevent trapping.  To assure complete drainage, optional intermediate drain headers are available.  Attached to the 180º return bends, the drain headers provide positive water drainage and protection from freeze-up.

Performance
Xchanger engineers use a computer model to analyze heat exchanger performance based on the best available engineering practice.  A specifically designed program calculates housing material thickness based on the ASME code.
