The solids-laden stream of liquid enters the separator tangentially through the entry nozzle and is directed and accelerated by the velocity plate, creating a strong centrifugal force on the flow. The faster liquid combined with the geometry of the exit tube creates a vortex in the middle of the vessel, maintaining the speed of the liquid.
Due to their higher specific gravity, the solids stay outside the spinning liquid at the vessels’ inner wall circumference. As these solids reach the spin plate, they breach the openings where the liquid reverses direction guiding the solids to the vessels’ exit tube.
Solids are retained in the collection chamber outside the influence of the vortex. The collected solids settle at the bottom of the separator until exiting through the purge system.
GWS’ Centrifugal Separators can be installed in either full flow or side stream configurations and are designed as a self-contained unit for cooling towers and cooling systems. GWS’ low energy high efficiency separators are also intended to optimize removal of settling solids, fabricated domestically, built to ASME standards and ideal for a range of applications where filtration is essential for 10+ micron sized particles.
Available for either basin sweeping or slip stream installations with a full set of options to suit your needs. The CSS (Auto-Purge System) and CSR (Closed Solids Recovery) models are compact, durable, economical and effective. Our systems maximize particle removal with low pressure drops resulting in significant energy savings when compared to a traditional system.
Both are built standard with a carefully selected closed coupled TEFC premium efficiency flooded end-suction pump. Or an optional self-priming pump is available if required. Separators are mounted on a welded structural steel powder coated base complete with connecting pipe manifolds made of welded and painted carbon steel, pressure gauge a UL listed pump control panel and basket strainer.
The CSS has a standard 24 hour purge timer/controller. Optional battery back-up closes the purge if a power loss occurs. The CSR includes a solids recovery tank (RT) with a pressure annunciator, sight flow indicator and manual isolation valves. Optional recovery tank service light illuminates when service is required. The CSR is ideal for hot and chilled water closed loops.
All come standard with 120 volt control circuit, HOA with remote command start-stop. Options include PCL controls for seven (7) day programmable purge control, InstAlert remote monitoring, BACnet® without panel mounted PLC or BACnet®
Self-contained and packaged with its own pump, a General Separator System may be installed as a side stream on the main system. An appropriately sized model will eliminate most of the troublesome solids in the fluid stream. The amount of filtration is based on the desired turnover rate.
This standard configuration demonstrates how GWS' Sweeper moves settled dirt gently along the basin in the tranquil water and does not re-suspend safely settled solids.
