| 1. Diaphragm, Stay Splitter plates |
We will build any rotor assembly sub-component individually or as complete sets.
|
|
|
| 2. Pin Racks |
| An improved metallurgical product. All pins are heat treated throughout their thickness for an extended life improvement over past induction surface hardening techniques. Pin center alignment is to a tolerance of + -.02 for exact smooth rotation and pin rack segment. |
|
|
| 3. Shell Plates and Covers |
| We will provide a partial or complete shell plate replacement specific to each contracts needs. Each shell plate is rolled to an exact radius for ease of replacement and fit. |
|
|
| 4. Gratings |
| We will provide a partial or complete shell plate replacement specific to each contracts needs. Each shell plate is rolled to an exact radius for ease of replacement and fit. |
|
|
| 5. T-bar Assembly |
| Gratings are a major structural steel member for rotor compartments in horizontal or vertical design air preheaters. Paragon can provide a complete range of grating assemblies at a competitive price. |
|
|
| 6. air preheater Rotor Modules |
Modular-constructed air preheater rotors bolt to the center post for fast field erection. Paragon can design and produce a complete range of replacement modules for all or modular rotors, modular designs include:
• Complete frames
• Sub-component assemblies
• Modules with installed basketed element |
|
|
|
| Radial/Axial Seals |
Radial seals are used to minimize the direct air to gas leakage that occurs at the center section or sealing surfaces in the air preheater. The seals are attached to each diaphragm of the rotor to maintain close contact with the sealing surface that separates the air and gas streams. |
|
|
| Circumferential / Bypass Seals |
The circumferential seals prevent air and gas from bypassing the heating surface through the space between the rotor and the housing shell. They are retained by mounting angles bolted to the circumference of the rotor. The circumferential seals wear against the sealing rings, which are welded to the housing of the air preheater. The bypass seals are mounted on the housing and seal against the rotor mounted T-bar.

|
| Element Tighteners |
| Element tighteners are driven into basketed element to help avoid continued fatigue failure of horizontal design basketed element. The tighteners re-applies compressive element sheet load, holding the element in place and extending material life. |
|
|
| Access Doors |
| A custom size door will improve outage productivity through ease of access, order a door big enough to use comfortably and safely. |
|
|
| Sealing Surface liner |
| Plate liners are an economical repair to your sealing surfaces. Fabricated for proper fit and plug weld installation to your existing sector surface, you can save thousands of dollars in labor and material when compared to the complete sealing surface assembly costs. |
