FAQs Cobra Cyclone Separator

A Cobra Cyclone Separator (or CSF-CRS unit) is a comprehensive packaged unit for the side stream filtration of closed and open circuit water systems.

All water systems experience problems such as corrosion, scaling and fouling which can cause high energy consumption and poor heat transfer. The use of a cyclonic separation removes up to 98% of corrosion products, sludge and debris, therefore maintaining the cleanliness of the system and ensuring it performs at its optimum levels for many years.

Driven by the inlet pressure, the water or liquid with particles enters the top chamber at a tangent causing a rotation, and accelerates through the tangential slots/holes in the top section of the separator, down into the centre section of the separator. This flow creates rapid rotation within the centre sector.

The rotation of the liquid forms a vortex in the centre of the separator. The centrifugal action forces the separation of heavy particles from the water. The separated particles accumulate in the bottom collection chamber where they are periodically purged.

Closed circuits (LPHW, MPHW, chilled etc)
Open evaporative cooling systems
Glycol circuits
Numerous process water applications

Cobra Cyclone Separators have no moving parts or filter elements, screens, bags or media which require periodic inspection and/or replacement. Therefore, they have many advantages compared to conventional filtration methods, including:

Lower chemical costs by reducing potential bacteriological food sources
Maintain design heat transfer levels by removing the sludge and debris which would otherwise build up and lead to higher energy consumption and poor circulation, with inconsistent environmental control within the building
Protect and extend the life of your systems
With the use of SOCOTEC’s Closed Recovery System (CRS), you can eliminate purged water losses, which means no requirement to make-up the system, introducing fresh mains oxygenated and bacteriologically contaminated water (even at low levels). It also avoids diluting chemical reserves in the circuit, including glycol
