Process Heat & Control Systems

TUBULAR ELEMENTS
are the most versatile of all electric heating elements, capable of being formed into virtually any configuration to heat liquids, air, gases and surfaces.
PIPE PLUG IMMERSION HEATERS
are mounted through tank walls using standard pipe couplings and are available in various sizes, heat capacities and sheath materials for heating oil, water or corrosive solutions. Built-in temperature control and terminal enclosures for special applications are available.
FLANGED IMMERSION HEATERS
allows high kilowatt ratings without an increase in length or multiple mountings that would be required in screw plug heaters. Thermowell, housing and gasket are standard, with multiple circuit wiring and terminal enclosures for special applications available.
MIGHTY-BLADE PROCESS HEATERS
has greater surface area than standard round elements, allowing more wattage or lower watt densities. Deep fryers and steam equipment in the food service industry are typical applications, but many industrial processes can be improved using the Mighty-Blade.
CIRCULATION HEATERS
are compact and efficient, contain a heater, tank and temperature control. Heating capacities from 1.5KW in several watt densities and sheath materials. Applications include fuel oil preheating, closed loop heat transfer systems, steam super heating, air or hot water storage tanks.
OVER-THE-SIDE IMMERSION HEATERS
are used in tanks where flanged or screw plug heaters cannot be installed, portability is required or where heaters must be removed for cleaning without emptying the tank.
PROCESS AIR HEATERS
Incoloy sheath tubular heaters are mounted in a steel flange and installed in ductwork or an oven wall, providing air temperature up to 750°F/400°C in forced air applications such as recirculating ovens, combustion air preheating and high temperature drying.
SPECIAL APPLICATIONS
Ogden can also supply specially designed heaters for unique applications, such as resin drying equipment or mold temperature controls.
PROCESS HEAT & CONTROL SYSTEMS
BigChief can design and manufacture a complete skid mounted or packaged Process Heat and Control System for many applications in many industries. Versatility, along with very accurate process control capabilities has the popularity of electrically heated systems increasing versus larger combustion fired systems. Efficiency is superior in that the total immersion of the heat source converts all electric energy into heat energy. OGDEN Systems and Assemblies can be considered wherever large volumes are being heated or when a process requires a significant temperature rise. A combination of multiple heaters and staging controls can heat extreme quantities or volumes. State-of-the-art control system components provide extreme accuracy. Processes to be heated are not limited to liquids, but can include gasses and vapors. Process heating application requirements can be met by BigChief with a code-stamped vessel or a skid mounted assembly consisting of heaters, vessels, pumps or blowers, meters, piping, pressure or temperature sensors and all instrumentation. In-house manufacturing of ASME coded pressure vessels and UL and cUL Listed Control Panels and other certifications including CE can be provided. Advanced design, manufacturing and testing equipment add to BigChief’s extensive capabilities to meet varied process applications. From just a couple of kilowatts to megawatts of power, BigChief can supply everything from concept through manufacturing to delivery to start-up with single source responsibility.

OGDEN systems are compactly designed, engineered to be efficient and thoroughly tested to perform to specifications. Located in Edinboro, Pennsylvania, OGDEN’s production facility has CNC machine tools, ASME certified welders, paint booth, overhead cranes and all other equipment necessary for the manufacturing and assembly of large Process Heat and Control Systems. Advanced design software and an experienced engineering staff provide extensive technical support including calculations and drawings. All vessels are hydro tested, all components are thoroughly tested to specification, then the entire system is tested under power before shipment. Materials ranging from mild carbon to exotic alloys are often specified. The selection is based upon temperature, pressure, corrosion considerations, and metallurgical properties. Heat treating for stress relief, passivation, cathodic protection, specialized welding or machining can be provided. Skid mounted heating assemblies are turnkey systems. Heater connections and control wiring are complete. Installation is reduced to offloading, setting the unit in place at the site, and providing process and electrical connections. Extensive experience in control application and in the manufacturing and application of tubular heater products gives OGDEN the capability to design and supply Process Heating Systems for the most difficult and unusual applications imaginable. |

Common process variables to be sensed and controlled are temperature, pressure, flow and level. Control Systems are supplied as part of the skid assembly or remote from the system. Only external line, load and sensor connections are necessary as the panel is completely wired and ready to install. Besides temperature, OGDEN can also design and supply Control Panels for other control processes using PLC’s and other components. UL and cUL Listing can be provided. The panel generally consists of a NEMA 4X or NEMA XII enclosure for floor, skid or wall mounting. Components are determined by specification, and can consist of the following:Process Control – Control results are virtually perfect using OGDEN ETR Controls with Smarter Logic. A wide range of sizes and features provide the ideal control for any process. The ETR can accept input from all thermocouples, RTD’s, and many devices with a current or voltage signal. Certain models have a NEMA 4X rating for applications requiring wash down or for corrosive atmospheres. For controls with a serial communications port, OGDEN-Link Communications Software allows multiple controls to be networked and remotely programmed from a host computer. OGDEN controls and panels can also be linked with other industrial software or Distributed Control Systems. The ETR-3 FM Approved limit control provides protection to the heat source and the process.
