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 requiring a stainless steel flow path for Deionized Water, either for use in parts cleaning or in other high-purity applications. Design features include electro-polished 316L stainless steel construction coupled with a patented design that incorporates patented tri-clamp sanitary fittings and high-performance heating modules.


Packaged into one cabinet, the Poseidon is for processes that need the heater and controller centrally located. This allows the operator to simply connect the power and plumb the water. Furthermore, all other connections and interfaces are internal and complete; making this a true plug and play solution.


Poseidon features a number of safeties. First, the heater is designed to CE and SEMI S2-0200 compliance, and the internal heating elements are also built to UL 499 listed. Moreover, standard safeties include an over-temperature and process thermocouple to maintain safe heating temperatures, as well as consistency and accuracy in fluid temperature.


The Poseidon is available in various outputs ranging from 24kW to 144kW and voltages from 208 to 480 VAC (3-phase). Operating temperature is 203º F (95º C) and operating pressure is 80 psi at 95º C.
