Overview
Anhui Xinfulong's PFA (Perfluoroalkoxy) heat exchangers are engineered for the most demanding thermal management applications in semiconductor, wet chemical, pharmaceutical, and new energy industries. Constructed from high-purity fluoropolymer materials, our PFA heat exchangers deliver exceptional corrosion resistance, ultra-low contamination, and reliable long-term performance in aggressive chemical environments.
PFA heat exchangers utilize tube bundles or plates made from this material to facilitate energy exchange between two fluids through thermal conduction, without any contact with metal substrates.- As semiconductor processes continue to advance toward higher integration and finer nodes, PFA has emerged as the material of choice for conveying and thermally managing ultra-pure liquids in key processes such as wafer cleaning, etching, and CMP, due to its excellent chemical inertness, extremely low precipitation rate, and outstanding processing performance.
Key Features
Superior Corrosion Resistance
-
PFA heat transfer tubes resist virtually all chemical agents, solvents, and acids — including sulfuric acid, nitric acid, hydrochloric acid, hydrofluoric acid, and aqua regia
-
Excellent resistance to environmental stress cracking and heat durability under high temperature
-
Less brittle than glass and graphite, more corrosion-resistant than most metals
Ultra-High Purity
-
100% PFA wetted path ensures no metal ion contamination or leaching of harmful substances
-
No softeners or plasticisers — ideal for ultra-high-purity (UHP) applications
-
Meets the stringent cleanliness requirements of semiconductor fabrication, including advanced node processes
Excellent Thermal Performance
-
High thermal efficiency with a compact footprint
-
Thin-walled PFA tubes maximize heat transfer while maintaining a high pressure rating
-
Overall heat transfer coefficient: 300–750 KJ/m²·hr·°C
