Particularly useful for degassing, this chamber (in combination with our basic digital control box):
- Prevents overpumping (e.g. boiling) of the product, by allowing the operator to limit the operational vacuum level (above that otherwise attained by unconstrained pumping).
- Provides for an automated vent.
- Allows for manual chamber ‘burping’ while the chamber is being pumped down to its setpoint.
- Permits a manual vent in the event of a power outage.
- Is rated for 10-4 Torr service.
A Digital VCC allows automatic digital vacuum cycle process control. The following is an example process enabled using our Basic Digital VCC:
- Operator checks/selects soak time and vacuum setpoint, and presses ‘start’ to initiate automated process …
- Chamber is evacuated to vacuum setpoint with LV pumping system
- Operator may manually ‘burp’ the chamber before the chamber reaches setpoint.
- Operator may manually input a second/third etc. setpoint once the previous setpoint has been reached. Subsequent setpoints must be in a sequence of increasing pressure so as NOT to reset the soaktime timer.
- Chamber is held at vacuum setpoint for soak time, and then vented
(Operator can manually override the vent) - Customisation of this basic process is available for a fee, which will include the price for additional or alternative hardware if required.
