ABSTRACT:
A combination pump and heat exchanger assembly in a manufacturing process temperature controller uses a cast metal pump case with two upwardly opening sockets receiving the lower ends of two tubes, one of them communicating through the case with the pump impeller intake and the other with the impeller discharge. Closed circuit and open circuit versions are shown. In both types, the tubes are constructed to function as tanks, at least one being a heat exchanger unit, and they are readily and removably secured to the case by threaded fasteners and are sealed therein by compression seals. The heat exchanger tubes employ electrical heating elements or chilled liquid piping units therein. A controller including a microcomputer responds to temperature of liquid pumped from the assembly through a process to be temperature controlled, and returned to the assembly, to control an electric heater and/or a motor-operated modulator valve discharging to drain while cool make-up water is admitted. The combination is self-contained and wheel mounted for mobility to facilitate connection to and disconnection from the process equipment.
