	DuraMax™ Radial Seals The DuraMax seals incorporate unique, self-adjusting bellows that ensure positive contact with the sealing surfaces. The rugged construction of the seal guarantees that they will withstand erosion, corrosion and soot blowing. When sealing edge wear does occur, they can be readjusted, rather than replaced, reducing maintenance costs. [Back To Top] DuraFlex™ Circumferential/Bypass Seals The DuraFlex high-performance circumferential and bypass seals use a patented revolutionary interlocking design. This design reduces the air gaps normally found in other circumferential or bypass sealing systems. [Back To Top] DuraShield™ Performance Coatings DuraShield™ is a high temperature, corrosion resistant coating with a high level of lubricity, which maintains the flexibility, durability, hardness and temperature resistance needed in the harsh environments found in an airheater. [Back To Top] Basketed Elements The air preheater is a regenerative rotating heat exchanger in which exhaust gases and ambient air pass through a slowly rotating cylinder filled with metal element (basketed element). The exhaust gases heat the rotating element which, in turn, preheat the air before entering the boiler. The element comes in a variety of configurations which the company manufactures to extremely tight tolerances. The manufacturing plant is ISO 9001 certified, which further assures product quality. [Back To Top] Hopper Level Detector The DuraGuard™ non-contact hopper level detector features a uniquely simple solution to your fly ash measurement challenges. Gravity does the work. The vacuum present in a negatively pressurized hopper (in a balanced draft boiler) pulls the detector’s flapper closed. When the hopper fills above the detector's pipe opening, vacuum is lost and the flapper falls open to energize the switch, sending an alert to the operator. [Back To Top] DuraPro™ Service Paragon prides itself in being a full service organization dedicated to customer service. The technical support staff averages more than twenty years experience in the power generating industry, and the technicians have worked on virtually every type of issue related to the maintenance and operation of an air preheater. The technical support staff is readily available to perform inspections, supervise installations, assess overall performance, analyze part replacement and recommend upgrades. The company also offers a Rapid Response program, which provides technicians within 24 hours to assist the client in recovering quickly from an unscheduled outage. [Back To Top] DuraCare™ Maintenance Program The DuraCare Maintenance Program combines the best of Paragon’s services to form a comprehensive maintenance service program that is designed to remove the uncertainty of labor costs associated with keeping an air preheater operational. The objective of this program is to offer a cost effective way to maintain an air preheater and ensure the maximum efficiency and performance of the unit. [Back To Top] Standard Components Paragon provides standard replacement parts for rotary regenerative air preheaters. These products undergo the same stringent manufacturing processes as all our products and are built to meet or exceed original equipment manufacturing requirements. We are proud to provide a full line of replacement parts for the air preheater, including:	Patent Summary
