CHAPTER 1
INTRODUCTION
Thermo Scientific’s Model 1160 Zero Air Supply converts ambient air to pollutant-free
air. Table 1-1 describes the pollutants that can be removed, the method of removal, and
the removal component.

BASIC PLATFORM
Although the Model 1160 can purge all the pollutants shown in Table 1-1, many
applications do not require the air system to eliminate the full range. Therefore, the
Model 1160 is designed as a basic platform to which a number of options can be added.
The exact configuration of each system depends upon the application and the pollutant(s)
to be eliminated. The basic Model 1160 platform consists of the following:
•
Electronics
. Control instrument power, front panel display and I/O.
•
Cooling loop/coalescing filters
. Remove water.
•
Regulator
. Controls output pressure.
•
Single Scrubber
. Choice of removing NO
