Continuous Weld
> Weld locations vary GENERAL INFORMATION
> See engineering standard E1-14
A regenerative thermal oxidizer (RTO) is an industrial process that
Seal Weld destroys air pollutants emitted from process exhaust. These gas
> Weld locations vary streams are usually produced by industrial process ventilation, i.e.
> See engineering standard E1-14 paint booths, printing, and paper mills. Fans are tested at the shop
with a Soap Bubble Test to check for leaks.
Gasketing - Fan Construction
> Double gaskets required > Solid drive side on housing (no drive plates)
> Bolted connections must have close centered hole patterns
Shaft Seal (3” to 4” centers) Includes: inlet and outlet flanges, access
doors, cover plates, inlet funnels, split housings, etc.
o
Pedestal Foot Gussets > Not recommended for applications over 600 F
> Dampers (if required) must have stuffing boxes

Centering Plates - Gasketing
> Use silicone sponge & silicone caulk
> Use on all connections: inlet/outlet flanges, funnel, inlet
plate, access doors, split housing, etc.
> If constructed with a split housing, centering plates are
required to seal open areas by shaft seals and inlet funnel or
inlet plate

- Shaft Seals
> Friction type
> Single Carbon Ring type
> Commercially available carbon ring or others seal
- Special Requirements (sales to specify)
> Pedestal – Concrete requirements
> Fan Base – Construction based on how fan will be mounted
in field
> Fan Operation (VFD, Cycling, Bake Out conditions)
