1-2 Sand and Gravel Automatic Backwash Filters

Sterling/Sterlco sand and gravel filters are shipped complete with:

•Tank

•Valve manifold

•Gauges

•Initial charge of sand and gravel

The system switches valves automatically. Two backwash control mechanisms are available. Backwash cycles can be based on a time cycle (SGM-250A) or pressure differential across the unit (SGM- 250P).

SGM-250A sand and gravel automatic backwash filters are available in a 250-ton (756,000 Kcal/hr) model for cooling towers and a maximum-capacity 500-ton (1,512,000 Kcal/hr) chiller model. The SGM250A model is equipped with automatic valves operated from a timing device so that the backwash cycle automatically activates on a periodic basis.

Filters must be installed in a bypass line so that plugging of the filter or temporary shutdown required for back washing does not hinder process operation.

1-3 Centri-Separator Filter Systems

Sterling/Sterlco centrifugal separation systems are used on cooling tower or chilled water systems requiring large capacity, heavy-duty suspended solids removal.

The Centri-Separator System (CSM-150) is designed to handle up to 150-ton (567,000 Kcal/hr) cooling tower systems and up to 300- ton (907,200 Kcal/hr) chiller systems. The CSM-150 includes a centrifugal separator, 1/3 hp (0.25 kW) pump, 1/2” PVC electrically- activated ball valve, and a 115 volt single-phase 60 hertz control station. The CSM-150 can be mounted on a pump tank or piped in a bypass line. The system performs all operations, including separator purging, automatically.

The CSM-400 is designed for larger tower water system applications; up to 400-ton (1,512,000 Kcal/hr) cooling tower systems and up to 800-ton (2,419,200 Kcal/hr) chiller systems.
