HFC Series – Multi-Unit Finned Tube Air Preheater with Heresite Coating

HFC Series air preheaters feature a multi-row, multi-unit configuration with spiral-wrapped aluminum fins on carbon steel tubes, optimized for high-efficiency air preheating in corrosive or humid environments. The entire housing and heat exchanger bundle are Heresite-coated, providing superior resistance to chemical attack, moisture, and thermal cycling. An airtight enclosed header prevents leakage, while removable heat exchangers simplify maintenance or full replacement. Engineered for boiler combustion air systems and industrial ventilation lines, the HFC Series combines modular construction with corrosion protection for extended operating life in aggressive service conditions.
