Abstract
A heater for fluids, the heater comprising a conduit having a wall and a surface, the conduit being configured to convey a fluid. In one arrangement, the conduit surface is roughened to mechanically secure a coating thereto. A conductor, configured to be electrically resistive and to extend over at least a portion of a roughened surface, and to adhere thereto throughout variations in operational temperatures thereof. The heater provides a clean, particle-free, non-reactive, non-trapping, ultra-pure, thermally tolerant, sealed system. The system maintains process fluids clean, even upon system failure, at contaminant levels below parts per billion, or even parts per trillion. In one arrangement, the heater comprises a quartz conduit with an electroless nickel plating of an engineered thickness on an external surface forming a resistive heater. The resistive heater conducts thermal energy through the wall of the conduit. Clean fluids pass on the inner surface of the conduit wall and are heated by a combination of conduction and convection. Thus, the fluid is not exposed to conventional immersion-heating elements which may contaminate.
