Heat Exchanger Station (3507)
The process consists of a water process tank with two pumps: one circulates water through a 6 kW electric water heater powered by a 3-phase solid state drive with a 4-20 mA driver control circuit; the other circulates water through the tube side of a shell and tube heat exchanger, then returns it to the water process tank.
Supply and signal lines to an I/P converter, RTD to current, thermocouple to current converters, diaphragm-actuated control valve, and solid state drive are terminated at quick-connect fittings on the main control panel. Mounted on the main panel are the microprocessor-based controller, two-pen strip chart recorder, and pump controls.
Supporting courseware is comprised of 20 laboratory exercises, written specifically for the mobile Heat Exchanger Process Trainer.
