C-Series Model offers the ability to remove the fin-tube core from either side of the housing without disassembling the gas duct. A range of gas connection sizes and types are offered to match your system requirements. Exchanger also offers the ability to have separate cores within a single housing with separate or shared access panels. In the first stage, air passes through a prefilter and is then cooled to 50oF (10oC). Cooling the air condenses humidity in the process. The second stage reheats the air to 75oF (24oC) with steam. In the last stage, air passes through a HEPA filter. The process provides filtered air at a consistent 75oF with 40 percent relative humidity.
