SP Series
CALL FOR PRICING AND DELIVERY OPTIONS
The Process Technology SP Serpentine Series Coil is an efficient, long-life immersion heater engineered for heating and cooling corrosive chemical solutions in industrial environments. Constructed from heavy wall, 20-gauge tubing in steel, 316 stainless steel, or titanium, this serpentine coil offers superior chemical resistance and optimal heat exchange, ideal for applications like metal finishing, chemical processing, and rinse tanks. Its low-profile design maximizes space efficiency in tanks with limited room
