Bakeout Control Unit BCU14


The BCU14 Bakeout Control Unit is a microprocessor controlled device for independent control of either two heating zones of a vacuum system or a single heating zone and a sample heater inside e.g. a preparation chamber. Heating operation for either one sample and one chamber or for two chambers is factory pre-set and cannot be modified by the user. An additional option allows the customer to independently control other non-regulated heaters such as those used for ion pumps. Unit can be remotely controlled via RS232/485 or Ethernet interfaces.


The main tasks of the BCU14 are regulation and stabilization of (i) the power supplied to the heaters in order to achieve a required bakeout temperature in any given zone, and (ii) parallel control of unregulated heaters (on valves, ion pumps, etc.). Target temperature, bake time and ramp times are all user-defined.

Additional information

The BCU14 Bakeout Control Unit controller can be supplied in a 3HE 19″ enclosure unit with steering power components (one or two units - 2 heat zones per unit) or for 19″ rack mounting with external power components.
