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‐V model fluid coolers. Note, that the package 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.

The pump package manifolds are usually equipped with
pressure gauges, automatic air venting valve, draining
and other valves.
