Technical Information
Description of the TwisTorr 404 FS
The pump can be water cooled or air cooled: in the first case the
customer can use the dedicated channels on the pump body, in the
second case an external optional fan is available. A thermistor sensor
is mounted near the upper bearing to prevent the pump from
overheating.
If the thermistor reading exceeds 60 °C the pump fails and stops with
Error Code = 2. If the thermistor reading is below 0 °C, the pump
fails and stops with Error Code = 1 (see Controller Manual).
The pump can operate in any position and can be supported on the
high vacuum flange. The connection of the forevacuum on the side of
the pump is a KF 25 flange.
