PVDF/PFA Ultra-Pure In-Line Fluid Heaters

PVDF/PFA Ultra-Pure In-Line Fluid Heaters

Heateflex’s series of Ultra-Pure In-Line Fluid Heaters are designed for use in industrial fluid heating applications such as those found in the semiconductor, solar, MEMS manufacturing, and other industries which require the most exacting standards of purity. Constructed of the highest quality fluoropolymer materials, these heaters are custom designed and built for use with deionized water and lower aggressive process chemistries. The Heateflex PVDF/PFA In-Line Heaters are ideal for recirculation and point-of-use applications and have small footprints, which results in less space and easy integration into current systems. These heaters are available in 1-30 kW and in worldwide voltages.
