PFA Immersion Tank Heaters are PFA immersion tank heaters. They feature a heating element encased in PFA (perfluoroalkoxy polymer) material and can be immersed directly into liquids to heat them. A detailed description follows:
Structural Features: These heaters typically consist of a stainless steel heating element encased in a thin PFA fluoroplastic tube. The heating element is encased in a special encapsulation process to reduce air entrainment and improve heat transfer efficiency. The connecting wiring harness is encased in a PTFE film and enclosed in a PTFE housing. The connector is sealed to the tank via an expansion fitting. The heater head is machined from solid PTFE with no mechanical joints. The heater tube and connecting wiring harness are precisely welded to prevent fluid intrusion.
Performance Advantages: PFA offers excellent high-temperature and corrosion resistance, maintaining stability in extreme temperatures ranging from -200°C to +260°C. It is virtually inert to all chemicals and can be used to handle corrosive liquids such as strong acids and alkalis. This heater also boasts high heating efficiency, with some models boasting heating coil efficiencies exceeding 99%. It also features microprocessor-controlled temperature control, typically with a temperature accuracy within ±0.1°C.
Applications: Widely used in the electroplating, vanadium liquid flow energy storage, chemical, food, environmental, medical, and semiconductor industries. For example, in semiconductor manufacturing, it can be used in ultra-clean process fluid transfer systems to ensure temperature stability during the transfer and use of high-purity chemical reagents.
