DWEER Energy Recovery Device
Brand: Flowserve CorporationThe Calder DWEER work exchanger is the most efficient energy recovery device (ERD) ever developed.
It can recover up to 98% of the energy in the brine waste stream, which is then used to pressurize raw water and reduce the energy input for the high-pressure feed pumps up to 60%.
With the DWEER, the high-pressure pump does not have to be connected to the energy recovery device.
This permits the use of fewer, but larger, more efficient pumps.
Features- The Most Efficient Energy Recovery Technology Available Today.
- No Other Technology Achieves Higher Efficiency Or Lower Plant Operating Costs.
- Its Unmatched Operational Flexibility, Specifically Its Wide Operating Range And Tolerance Of Foreign Objects, Translates Into Extremely High Availability And Reliability.
- Wide Operating Range Enables Plants To Easily Accommodate Normal Fluctuations In Demand.
- LinX™ Valve Offers Precise Control Of The Energy Transfer Mechanism As Well As The Operating Speed Of The System.
- Materials And Clearances Can Pass Objects Up To 30 Microns Without Incurring Damage, So Special Flushing Procedures, Strainers Or Filtration Systems Are Not Needed.
- Quiet Operation – Less Than 83 Decibels – Means Noise Hoods Or Enclosures Are Not Needed.
- Its Installation Versatility, Basic Header Requirements And Lack Of Extra Equipment Such As Noise Enclosures, Strainers And Filters Greatly Simplify Plant Construction.
- Extremely Low Maintenance Costs, High Availability And 25-Year Service Life Contribute To Low Total Cost Of Ownership.
