The ADI
1035 Bio Console Basic Module
The Bio Console integrates all the necessary
peripheral equipment to run and control a bioprocess. Since the unit
is modular, it can be configured to accept only those modules necessary
to carry out the control a specific bioprocess. If the process control
strategy should change the Bio Console can be easily reconfigured
by adding or changing modules.
General Description:
The basic Bio Console is configured to accept
3 fixed speed pumps and one variable speed pump. The pump heads which
are added to these drives are peristaltic tubing pumps and are available
in various sizes. The Bio Console accepts up to 4 rotameter flow tubes.
The flow range and gas type can be specified for the application,
as required. Each rotameter provides a needle valve for manual adjustment
of gas flow. A separate 3-way valve allows the operator to select
gas flow to the sparger or gas overlay. A third position allows the
ga flow to be shut off. In addition, solenoid valves are available
for each rotameter to control gas flow as a function of dissolved
oxygen or pH setpoint. |
As an option the rotameter assemblies can be replaced
with mass flow controllers. The Bio Console can accept up to 4 mass flow
controllers, of various capacities. Two of these mas flow controllers
can be controlled remotely by the ADI 1030 Bio Controller. The Bio Console
also can incorporate a motor speed controller, foam controller and temperature
controller. For temperature control, several options are available. A
thermocirculator can be installed which allows water to flow to the heat
exchanger or jacket of the bioreactor. As an alternative, a heating blanket
or heating element can be plugged into the Bio Console. For cooling purposes,
a cold water solenoid valve can be installed. A foam controller may be
installed in the Bio Console which frees up additional space in the Bio
Controller for measurement and/or control of another parameter.
All devices described above are controlled from the ADI 1030 Bio Controller
which installed above the Bio Console.
The basic Bio Console includes all the necessary connections for water
supply, gas supply and power. Manifolds allow mixing of gases. Water supplies
are also brought to a manifold and a separate connection is provided for
cold water supply to the air outlet condenser. A central power supply
switch controls power to the various modules as well as the Bio Controller.
The power section of the Bio Console also includes fusing for protection
of the Bio Console and all components. An "alarm" LED is provided which
can be used to provide a general alarm status based on sensor input signals.
