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. home | about ogden | products | | contact ogden OGDEN MANUFACTURING CO. 103 Gamma Drive, Pittsburgh, PA 15238 phone 800-OMC-4921 or 412-967-3906 fax 888-OMC-9890 or 412-967-3930
