Fluid Coolers Pump Package
Fluid Coolers , if equipped with such option, would have a pump package box. Pic.D.6 below shows general layout
of pump packages, used for NG-Z (left) and NG-V (right) fluid coolers. Note that the package used with NG-V
coolers could be mounted onto the fluid cooler directly (standard) or provided separately .

Pump (38) establishes glycol mixture circulation through the fluid cooler and dehumidifier;

Expansion tank (39) compensates for temperature-based glycol volume fluctuation;

The pump package electrical sub-panel (40) contains the pump package electrical power and control
apparatuses.
o
Due to the compact design of the fluid cooler NG-Z, the electrical sub-panel includes power and
control apparatuses for the fluid cooler and the pump package itself.

The pump package manifolds are usually equipped with pressure gauges, automatic air venting valve , draining
and other valves.
