Capacity Control

Bison turbo blowers are designed to utilize variable Inlet Guide Vanes (IGV), variable Diffuser Guide Vanes (DGV) or a combination of IGV and DGV configuration for capacity control and provide stable partial load performance. The variable IGV has a wide operating range while variable DGV offers efficient single blower control.

CATERING FOR
DIFFERENT
CAPACITY NEEDS

Bison turbo Integrated Centrifugal Blower is designed to cater
for the different capacity needs of a waste water treatment
plant. The blower can be equipped with various capacity control
options to meet the demands of specific discharge pressure and
volume. Flexibility and efficiency is an integral part of the bison
turbo blower.

Capacity Control

THE CONTROL
SYSTEM

Comprehensive protection
and control

Vibration sensor installed between
tilting pad bearing and oil sealing
provides constant monitoring of the
pinion's operation condition to
protect the rotor assembly.

Temperature sensor monitors the change of
temperature in the tilting pad bearing to
ensure a safe operation.

Modulating
Blow-off Control

Blow-off silencer is used as a control mechanism to maintain constant pressure. This prevents frequent blower stop-start as excess gas is discharged
through the blow-off silencer when the pressure
reaches critical point.

INDEPENDENT LOCAL
CONTROL SYSTEM

Programmable logic control system provides optimal functionality and practicality for the Bison turbo blower.
