o
Each compressor module is equipped with High and Low Pressure switches
Transducer
and

Pressure Switch
to protect the compressor and control its operation.
Main Electric Panel,
apart from devices listed above (control board, OP, etc.) also contains
Voltage Monitor;
some
optional control sensors and devices such as an air pressure differential sensor, current sensor(s). It may also be

Dry Cooler Layout and Components
.
The general layout of AC options is shown on Pic.D.5 below with the dry cooler
NG-V-12,
equipped with additional
pump package
(Fig.1)
and
NG-V-32 (Fig.2)
as an example. While layout and main components are similar for all
applicable AC options, there are some deviations (number of fans, composition, etc.). Refer to
AC Options Basic
View
(
Basic Information
chapter) for additional information.
•
Cooling (AC)
coils
(31) (where heat from glycol mixture is rejected to the ambient air) is mounted onto metal
frame, upstream (before) the
fans
(32), that pulls the air through the coils to absorb the heat.
o
Normally, dry cooler would have multiple coils and fans. Cooler NG-V-12 (Fig.1), comprised of two
coils, mounted on the angle to each other, and two fans, presents a single block. Depending on the
capacity, cooler could be comprised of up to six such single blocks, stacked side by side on the same
frame and manifolded together
–
NG-V-32 is comprised of three such blocks.
•
Cooler
piping connections
(33) are identified respectively (IN
–
OUT);
o
In some cases, dry cooler piping connection(s) may be located within
pump package
box (37), if dry
cooler is provided with one.
