HTF Systems Increase Energy Efficiency

HTF systems deliver accurate temperature control with heating capacities up to 96 kW per zone and temperatures up to 600 degrees F (316 degrees C). Heating and cooling capabilities eliminate thermal shock and maximize energy efficiency. Available in single-, dual- or triple-zone configurations, the systems' design increases heater and fluid life for lower maintenance and production costs. The microprocessor control technology improves temperature control accuracy and part quality.

Hot-Oil-Circulating Temperature Control Unit

Hot-oil unit will circulate and precisely control the temperature of oil flowing through your process. Maximum temperature is 450 degrees F (232 degrees C). 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.

Thermal Fluid Systems

Customized and complete thermal fluid (hot oil) heater systems are available to 14 million BTU/hr and temperatures to 750 degrees F (399 degrees C). The four-pass, high efficiency design with preheated combustion air requires minimal floor space. The design allows for high fluid velocities within the coil, which translates to low film temperatures. The ASME-stamped heaters can be skid-mounted at the factory with a circulating pump and expansion tank. Skid piping includes control valves, secondary loops and heating/cooling loops.

Thermal Control Units

Water-cooled chillers are designed to remove heat from a process and discharge it to an auxiliary facility water supply such as a central chilled water system or cooling tower. The facility water source does not need to be temperature controlled, but water sources exceeding 95 degrees F (35 degrees C) may require special design features. Affinity thermal control units have a small footprint, modular design, and quiet operation, with capacities up to 100 kW.
