Best PFA Inline Chemical Heater

Basic information

Best-in-class chemical heater

The Best PFA Inline Chemical Heater is designed for hydrofluoric acid (HF), potassium hydroxide (KOH), and other chemistry compatible with PFA. It uses a PFA insulated electrical resistive element heater and is suitable for safely heating acids, bases, DI water, and other noncombustible liquids up to 210°C

This series of Precise Heater Ultra-Pure Inline Heaters is designed for use in ultrapure environments and industrial fluid heating applications such as Semiconductor-, PCB-, MEMS-, Electronics-, LED-, Flat Panel-, Solar cell Manufacturing, Chemical Processing, Aerospace, Life Science industry and other applications which require the highest standards of purity. Constructed of PVDF or PFA materials, these heaters can be.

Best PFA Inline Chemical Heater

Inline Chemical Heater Performs Unmatched Semiconductor Process Fluid Heating

Now heat semiconductor process fluids up to 210°C!

Faster heatup: Single heater chamber sizes up to 18kW.

Rapid installation: Customized plumbing connections

Long heater life for reduced cost of ownership (COO):

Patented heater gas purge system continuously removes any chemical permeation and ensures long element life

Long heater life and clean operating: Patented heater gas purge system continuously removes chemical permeation and ensures exceptionally long element life. This system also protects against any potential ionic contamination of the chemistry.

Rugged construction: Thick walled chamber provides long service life in the harshest high temperature applications.

Exceptionally clean performance: Thick fluoropolymersheath minimizes permeation. Element purge monitoring minimizes ionic contamination potential. Cleanroom assembly and testing ensures the highest manufacturing standards

Outstanding chemical compatibility: All fluoropolymerwetted parts compatible with virtually any chemistry

Excellent temperature stability: Low watt density design enables accurate control of process temperature.
