ABSTRACT:
A heating system for non-contaminatingly electrically heating a de-ionized fluid includes a master heater unit having a heater body with an inlet an outlet at one end, a tube which channels entering fluid centrally through the body to a point distally spaced from the outlet, turbulence creating plenum plates on the tube and a resistance heating element enclosed in an inert corrosion resistant PFA jacket and helically wound about the tube. The outlet of the master unit is connected to the inlet of a similar slave fluid heater unit. The heater units are each grounded by a ground wire having a tantalum or platinum tip exposed to the fluid. The heating elements are controlled by a solid state relay responsive to minimum fluid flow rate sensor, high temperature limit controller, fluid level controller and a tip-over sensor. A microprocessor compares the fluid flow rate through the system with the system outlet fluid temperature and controls the relay to limit the maximum temperature of the fluid exiting the system to a pre-set value.
