GAS SUPPLIES
This Anaerobic Cabinet requires two gas cylinders, each fitted with a two stage regulator. The output
sides of the regulators should have a range of 0 - 50 p.s.i. (3.3 bar).
One gas cylinder should contain:
10% Hydrogen + 10% Carbon Dioxide + 80% Nitrogen
The other gas cylinder should contain:
Oxygen free Nitrogen
CAUTION: GAS CONTAINING MORE THAN 10% HYDROGEN SHOULD NOT BE USED
UNDER ANY CIRCUMSTANCES
The gas pressures at the inlets to the cabinet should be approximately 30 psi (2.0 bar) and the gas
flows are as follows:
MIXED GAS 25L/min
N2 25L/min
The diameter of the pipes connecting the cylinders to the cabinet should be selected according to the
length of run to give a minimum pressure drop, this will give maximum gas utilisation.
The cabinet is fitted with 6mm diameter "push in connectors" for the gases.
ELECTRICAL SUPPLIES
VOLTAGE: 220/240 V.A.C.
CURRENT: 5 AMPS
FREQUENCY: 50 Hz
CAUTION
Switching the Anaerobic workstation “OFF” before it has reached its working temperature can
cause the “THERMAL FUSE” protecting the heater to rupture.
We recommend that the heaters are switched off at the control panel if any work is being carried
out on the unit requiring switching “OFF” and “ON” or during any commissioning tests.
