SPIROGUARD® Screen

Shaftless Spiral Screen as Compact Cleaner or Channel Screen
SPIROGUARD® Shaftless Screw Conveyor Screen

The SPIROGUARD® combines screening, conveying, dewatering and removal of solids from effluent and process streams in one compact machine.

The unit is robust, easy to install and, with only one moving part, virtually maintenance free. Slow speed combined with automatic intermittent operation ensures a reliable and efficient system.

SPIROGUARD® Channel Screen (CS) SCREEN
SPIROGUARD® CS Screens can be installed for a variety of flow rates and upstream and downstream water levels. The angle of inclination depends on the concrete channel specifications. 

Typical applications are:

  • Inlet works in sewage treatment plants
  • Pulp and paper industry
  • Wine industry for extraction of seeds and skins
  • Food industry

SPIROGUARD® CC SCREEN
The Spiroguard® CC Screen is designed as a standalone unit for pump-fed applications. Ideally suited as a tanker reception facilitator screening seperation unit, it is robust and easy to install. With only one moving part, this unit is virtually maintenance free. Slow-speed combined with automatic intermittent operation ensures a reliable and efficient system.

 

Technical details
