Process chamber purge is required to operate your spin processor.
Just a small amount of N2 or CDA (Clean Dry Air) is needed.
A field proven feature, NOT a limitation, typically found
in much more elaborate process equipment.
This graphic represents the functionality of the seal purge.
The seal's purpose is to separate the process chamber from the motor and electronics
in order to insure long, service-free operation.
We have had no failures as a result of process chamber flooding
since its implementation in January 2004.
Its second purpose is to operate the vacuum control valve, as well as many more
pneumatically controlled options now available.
It should be noted that a differential pressure MUST also be established between the spin processor and its environment so there is sufficient gas flow through the motor seal purge. Please review the video on the right for an illustrated explanation.
NOTE: This is an advanced functionality,
NOT an unnecessary, wasteful extravagance which others would have you believe!
We are proud of the evolution of our product and feel that, for most users,
this is a solution, not a limitation. The consumption of a few cubic liters of gas
(typically N2, Ar or CDA) per hour is a small price to pay to
ensure indefinite trouble-free operation.
