Aries PFA IPA Heater

Aries PFA IPA Heater



The Aries PFA IPA Heater safely and effectively heats thermally-sensitive fluids such as Isopropyl Alcohol (IPA) and EKC photoresist remover. This heater is suitable for both single-pass and recirculating applications where process temperature, fluid cleanliness and safety are all critical. Therefore, Aries is an ideal heating solution for semiconductor manufacturing applications. Several optional controller packages are also available for the Aries on customer request.


This heater incorporates several design features for effective and safe heating to UL standards. For instance, the insulated housing is explosion-proof, dust ignition-proof, and dust tight. The heater features PFA tubing embedded in an aluminum heater core, and has a patented hermetically sealed electrical connection. Furthermore, the ground fault circuit integrator serves as a quick safety switch to prevent too much power into the heater. Finally, the independent fluid path permits the heater to heat flammable fluids.


This heater features a PFA tube for wetted surfaces. A PFA constructed fluid path that is independent of the heater element allows the Aries to effectively heat flammable fluids while maintaining high purity. Hermetically-sealed electrical and control connections, with thermocouples for process and over-temperature, ensure safe operation.


Heateflex can custom build Aries heaters to meet specific customer requirements. Various optional controller packages are also available upon request. Available models range from 2.5 to 9.0 kW, dependent on various voltages. Operating temperature is 203º F (95º C), and operating pressure is 60 psi at 95º C.
