1-1 General Description

Filtration is used on cooling tower systems or chilled water systems requiring removal of large, heavy-duty suspended solids. Four filtration systems are available; sand and gravel filters, centrifugal separators, bag filters, and strainers.

Sand and gravel filters use two layers of gravel and one layer of sand for filtration. It is piped in a by-pass configuration. A timer can be preset at any interval to automatically back wash the sand and gravel. The SGM-250A sand and gravel filter is designed to handle up to 250 ton tower systems and 500 ton chiller systems.

The Centri-Separator System uses centrifugal force by directing the water in a circular motion allowing suspended solids to drop out and be purged from the system. It is piped in a by-pass configuration and is supplied with an integral pump, electrically operated ball valve, and controls. A timer can be preset at any interval to automatically purge the separator. The CSM Centri Separator is available for cooling tower systems up to 400 tons and chiller systems up to 800 tons.

BFS bag filters use a 25-micron bag to filter suspended solids in either a by-pass or full flow piping configuration. A differential pressure alarm is available to warn when bag is full. BFS bag filters are available for tower systems up to 150 tons and chiller systems up to 200 tons.

SWF Series full flow filters use a strainer basket to filter the water. An 80-mesh strainer screen is standard. Other mesh sizes are available upon request. The filter housing, strainer basket, and flanges are made from 304 stainless steel. A differential pressure alarm and automatic purge valve are available as an option. SWF Series full flow filters are available for tower systems up to 650 tons and chiller systems up to 850 tons.
