Gas sampling and gas conditioning technology 10-1.1.1-ME

6 INTRODUCTION

The M&C BA-C air conditioning unit has been designed especially for applications where dry, cleaned

and hydrocarbon-free air is required, independent of gas cylinders.

Typical applications are hydrocarbon measurements with flame ionisation detectors (FID) and use as

a zero gas generator for the calibration of infrared (IR) analyzers or for production of dilution gas for

M&C dilution probes.

The M&C BA-C air conditioning units are compact, operator and service-friendly 19” plug-in units for

19”-rack mounting or wall mounting.

7 FUNCTION

Figure 1 Function diagram of BA-C air conditioning units

The functional principle of the M&C combustion air conditioning unit is divided into two sections (see

Figure 1):

 Hydrocarbon elimination section

 Gas conditioning section

Hydrocarbon elimination section:

Catalytic oxidation Fl1 of hydrocarbons at a temperature of 932°F at the surface of the

platinum/palladium filling. The optimum catalyst temperature is adjusted ex works at the temperature

controller B1 of the air conditioning unit.
