Gas sampling and conditioning technology 10-1.1-ME
The catalyst cartridge is installed in a heat-insulated tube furnace. A special screw-type adapter
enables removal of the hot catalyst cartridge without the aid of tools (see 15.4).

The combustion air unit is operated with maximum 5.8bar.
Before removing the catalyst cartridge, the system must be
relieved of pressure by moving the “Air/ON” switch into the
lower position!
In the event of incorrect operation, i.e. prior to removal of the catalyst or adsorber cartridge, the
combustion air conditioning unit is not relieved by moving the
“Air/On” switch into the lower position,
the compressed air discharges via specific bores when the screw caps are unscrewed.
The furnace temperature is electronically controlled and is preset at the works at temperature
controller B1 on the front panel of the combustion air conditioning unit to +500°C.
If the catalyst temperature is not reached, the gas flow is automatically interrupted. The status signal
is applied as a group alarm to the nine-pole subminiature connector (terminal point, see 12.2) on the
rear panel of the combustion air conditioning unit.
The adsorber cartridge is locked by means of a screw cap and can be removed without the aid of
tools (see 15.5).

The BA.. combustion air unit is operated with maximum 4bar.
Before removing the catalyst cartridge, the system must be
relieved of pressure by
moving the “Air/ON” switch into the
lower position!
The supply connections are located at the rear of the BA housing. These are:
- Supply socket for inlet connector for non-heating apparatus X1,
- Nine-pole subminiature connector X2 for status contact output,
- Combustion air inlet via: Ambient air suction filter F11 for BA-P4 version,
solenoid valve with
G 1/4”i for BA version,
- Combustion air outlet 1, hose connection DN 4/6,
- Waste air outlet 2, hose connection DN 4/6
- Condensate connection
G 1/8”i 3 at drain YA1
For the BA-P4 version, a built-in fan provides the necessary cooling of the swing piston compressor
M1. The cooling air discharges via ventilation slots in the BA housing.
