Specification Value

The oil level sight glass is a convenience item that is preferred by many users. The same purpose is, of course, served by either the dip stick or the sight glass.

Marley basins are used to permit the installation of towers on elevated platforms or foundations.

This is the simplest of several cold water basin designs available for the Sigma Steel towers. Because of its bolted construction, it has the advantage of being hot-dip galvanized after fabrication. Marley can also install a 10 gauge welded stainless steel basin for a Stainless Steel Sigma. See 24.

This could have a very beneficial effect upon your fire insurance premiums. Towers not able to meet FM require- ments may require the inclusion of a fire protection sprinkler system to achieve a comparable level of insurance premium cost.

These covers are designed to keep leaves and debris out of the circu- lating water system. They also serve to suppress algae formation by shielding the incoming hot water from direct sunlight.

In wooded or windy areas, these screens help to keep leaves or blow- ing debris out of the cooling tower and circulating water system.
