The
key to consistent long term heater performance is:
Heater design and catalyst quality
The catalyst impregnatedPre-forms
produced by Vulcan, used the most advanced Alumina fiber support
structure for the proprietary platinum catalyst. The composite is
specifically designed to offer the maximum area of platinum to the
gas as it passes through the heater.
The catalyst support fiber
produced by Saffil Ltd., is a 50% amorphous/50% crystalline high
purity alumina fiber of exceptionally high porosity specifically
designed to provide long term performance for Vulcan's heaters. With
fiber diameters of 3.00 microns and with one gram of Saffil offering
150-200 square meters of surface area for reaction sites, gas is
efficiently oxidized, releasing maximum heat while eliminating any
potential for gas slippage.
Catalyst Life - in excess of 40,000 hours
In case of process damage or catalyst
poisoning, see our Refurbishing page.
Typical operating temperatures of Vulcan
heaters in the range of 400 - 1000 degrees F demand the high
temperature stability of Saffil, which has a maximum operating
temperature of 2,000 degrees F.
