Hot-Oil-Circulating Temperature Control UnitHot-oil unit will circulate and precisely control the temperature of oil flowing through your process. Maximum temperature is 450oF (232oC). The oil temperature is continuously monitored with one thermocouple located in the oil supply line, which relays any deviation from setpoint back to the controller. A three-phase, flanged, low-watt-density immersion heater heats process oil. Heaters are vertically mounted to eliminate bending and stress that could cause premature burn out and are electrically interlocked to prevent their operating if the pump is not running or if low oil pressure exists. A bypass circuit incorporated in the system ensures heater flooding if there is blockage in the process lines, thus eliminating the possibility of heater burnout.
