Reliable debris removal for seawater, river and cooling water intakes. Rockerhill engineers and supplies cooling water intake screens, traveling water screens and traveling band screens that protect pumps, condensers, heat exchangers and RO membranes.
Stainless steel intake screen panel, ready for export shipment
Product Overview
A cooling water intake screen is the first line of defence for any plant drawing water from the sea, a river or a reservoir. It removes fish, seaweed, shells, plastics and floating debris before they can block pumps, foul condensers or damage downstream treatment such as seawater reverse osmosis (SWRO).
- Traveling water screen: continuous-duty mechanical screening with automatic debris removal.
- Traveling band screen: through-flow band design with mesh panels, high-pressure spray wash and debris trough.
- Bar screen: coarse and fine bar racks, manual or mechanically raked, as primary protection.
- Complete package: screen, drive, wash water pumps, control panel and installation guidance.
Why Rockerhill
