COMPONENTS & MATERIALS

Alliance Corporation has learned through experience of servicing and repairing oxidizers built by others that there is no benefit to cutting corners on materials and components.  We have deliberately chosen to use the most robust materials and highest quality components available.  You might consider that quality of our components, craftsmanship and attention to detail would lead to higher prices for our equipment, however, just the opposite is true.  We make up the difference in warranty savings.  Alliance Corporation equipment has a proven track record of extreme reliability and as such our warranty expenses are negligible.  Therefore, we are able to reflect warranty overhead savings in our upfront equipment pricing which you will find is among the most competitive in the industry.

Some examples of quality that set Alliance Corporation apart:

Plate.  Alliance Corporation fabricates all standard oxidizers out of 1/4" thick carbon steel plate.  Alliance also fabricates oxidizers out of stainless steel, AL6-XN® and Monel® when required for special processes.

Poppet Valves.  Alliance Corporation manufactures robust 2-way poppet valves for the inlet and exhaust of each bed.  The valve seats are machined from solid steel.  The valve disk is a steel plate disk sandwiched between a machined steel hub with a bolted and welded end cap.  The disk assembly is threaded on to solid stainless steel shaft and locked at three points.  The shafts are supported and housed in a purged pipe with self aligning guide bearings at top and bottom.

Actuators.  Alliance Corporation poppet valves are automated by specially built actuators with extended internal pneumatic cushions to reliably slow down the disk to ensure gentle quiet contact with the seat.   The actuators are fitted with mufflers to suppress pneumatic noise.  Our actuators are built to endure decades of continuous use with no appreciable wear.

Insulation.  The interior of the combustion chamber and heat exchange beds are insulated with 8” thick compressed ceramic fiber modules stud welded in place.  The interior of the inlet and exhaust manifolds and poppet valves is insulated with foil faced fiberglass pin welded in place.  There is no external insulation or cladding .

Media.  Alliance Corporation uses structured heat exchange media made of industrial porcelain.  Structured media has greater thermal efficiency and a lower pressure drop which allows for smaller, more efficient beds.  Structured media never requires additional material or leveling.  Structured media will last the lifetime of the RTO.

Ergonomics.  Alliance Corporation RTOs include a ladder and handrails for easy safe access to all components.  All ladders and handrails are galvanized to ensure a maintenance free durable finish.

Finish.  All Alliance equipment is sandblasted, epoxy primed and finish painted with urethane.

Control Cabinet.  The controls, including the Variable Frequency Drive (VFD), are housed in a single climate controlled enclosure mounted on the RTO and factory wired to all of the components.
