Vibration Troubleshooting Guide

Library, Technical Papers
Early detection and inspection of the cooling tower to find the source of the vibration (shaft misalignment, broken gear teeth, imbalances etc.) are key to avoiding downtime and more serious structural damage.

Penberthy NWH bronze steam jet heaters are available for freeze protection (installation by others) in cooling tower cold water basins.

Fluid Cooler Cold Weather Operation

Library, Technical Papers
Preparing a fluid cooler for cold weather operation or shutdown season is similar to an open cooling tower, but with additional requirements. This paper discusses special considerations needed for cold weather operation and freeze protection for fluid coolers.

Pump Flow vs. Gravity Flow

Library, Technical Papers
Is the cooling tower operating on pump flow or gravity flow? This question is often misunderstood and sometimes results in hydraulic or scope issues that could have been easily avoided.

Use of Vibration Isolators

Library, Technical Papers
Vibration isolators are used with cooling towers as a method to reduce the transmission of vibration, produced by rotating mechanical equipment or water flow, into or within a building structure.

Pipe Tap Requirements (48” — 144” diameter)

Library, Technical Papers
The taps should be located in the longest unobstructed section of straight pipe available and easily accessible, and at positions a minimum of 8-10 pipe diameters from any upstream interference and 4-5 pipe diameters from any downstream interference.
