Diff-Therm Platen Heaters
The Diff-Therm heater is a combination of high-quality, tubular heating
elements and grey iron castings (platens and rings) swaged together under
50 tons per square inch pressure. For over twelve years of service to
the vacuum industry in the United States and Canada, these heaters have
been the industry standard for long life, for uniformly distributed
process heat, and for efficient power generation.
Over the course of use heaters can go bad and need replacement.
HyVac now has available heaters for most US and foreign made diffusion
HyVac has available heaters for 2" through 48" diffusion
pumps in over 100 combinations of electrical ratings and casting sizes. We
also have heaters in custom casting dimensions and electrical ratings for
use on obsolete and foreign-made pumps.
