Accumulation Barrier For Applications with Particulate
Insulation Pillow for High Temperature Applications
The insulation pillow option ensures that the temperature at the gas seal membrane does not exceed it's capability. The insulation pillow is constructed with high density needle felted ceramic insulation wrapped with high temperature cloth and wire mesh. The insulation pillow is pinned snuggly to the liners or frames.
Bolt-On Liner for Style 500
The liner is attached with the fasteners of the upstream clamping bar.
Bolt-On Liner for Style 700
The liner is designed to be removed from inside the ducting to allow access to the fabric belt. The liner is attached with studs field welded inside the duct.
Weld on Liner for Styles 100, 600
The liner is field welded to the upstream inside edge of the duct. (3D view similar to Style 700 except without studs.)
A drain fitting machined out of PTFE material can be installed in the belt at the bottom of the expansion joint. If conditions are wet enough to cause pooling, specify a drain.
In certain conditions, a particulate deflector can be specified to reduce air born particulate from falling down into the expansion joint cavity. This is most common on vertical ducting with the flow direction up and an upstream liner overlapping the downstream duct. The deflector presents an angled surface to the flow and eliminates a ledge for build-up.
