PFA Immersion Tank Fluid Heaters

PFA Immersion Tank Fluid Heaters


The Heateflex Corporation’s Immersion Tank Fluid Heaters are used to heat fluid baths to a constant temperature, and for other liquid heating applications in the semiconductor, pharmaceutical, and biomedical industries that require the direct application of clean heat evenly and efficiently. These immersion heaters are compact and highly customizable, providing for a maximum of process work area and reducing the amount of chemicals consumed. These heaters feature all-PFA wetted surfaces, and are designed for use in tanks made of PVDF, PFA, or quartz (please contact Heateflex with inquiries about other tank materials). Rugged and durable, they’re designed to stand up to aggressive process chemistries, as well as deionized water. Available in grid, frame, and fence models, with outputs from 1 kW to 30 kW.
