Poseidon™ Stainless Steel Ultra-Pure Fluid Heater System

Poseidon Stainless Steel Ultra-Pure Fluid Heater System

The Poseidon™ Stainless Steel Ultra-Pure Fluid Heater System from Heateflex offers a unique option for manufacturing operations that require a stainless steel flow path for Ultra-Pure Water and Deionized Water, either for use in parts cleaning or in other high-purity applications. Constructed with the highest purity considerations in mind, Poseidon features electro-polished 316L stainless steel construction coupled with a patented design that incorporates sanitary fittings and high-performance heating modules. This is a great stainless steel water heater. Everything can be packaged into one cabinet, and is designed for processes that need the heater and controller centrally located: all you need to do is to plumb the water and connect the power. The versatile Poseidon can be tailored to meet unique applications in the biotech, chemical, food and beverage, medical device, pharmaceutical, and semiconductor markets.
