Rotor Post prepared and ready
for Cold End Modular Assembly Installation
A modular assembly installation would use the existing
rotor post, bearings, duct work, support framework, drive motors,
speed reducers and other major components. Modular type replacements
are also in-kind replacements allowing use of all the same components
( baskets, Seals, Bearings, etc.) that might be currently stocked.
Modular assemblies are significantly easier to handle and do not require
extremely heavy crane or rigging equipment. Modular assemblies can
be built to replace all or half of the rotor, only the affected portion
of an air heater, such as the cold end portion or smaller potions
of only a few sectors.

Modular Assembly being fitted
A modular assembly will take only a fraction of the
time to build, deliver and install as compared to a full rotor replacement
allowing a unit to return to service much sooner.
