City Councils employ Cobras for pipework Protection!
Posted: Thursday 2nd February 2006
Recurring Problems with Sludge build up in old Boiler pipework installations have been solved recently, when Wandsworth Council installed the Filter-less Cobra Cyclone systems to some of its large centralised District heating systems.
The Cobra System dirt separator, incorporating an in-line CRS Dirt Collection unit, was installed to completely remove the build up of Iron Oxide sludge & free limescale particles, which are commonly found in close–circuit installations.
The system was proven to massively reduce the number of Heating breakdowns & call outs, due to heat exchangers blocking, poor heat transfer & Valves continually failing.
The major advantages that the Cobra has over other filter systems or dirt separators are: No Filter media or elements to check or clean / replace
- No moving parts to wear and no backwashing required
- Provides continuous cleaning and filtration without maintenance
- Zero water or chemical loss from the water circuit
- Compact design – unit can be moved from site to site easily
- High Performance. Removes all solids down to less than 20 micron continuously
- Suitable for both Heating and Chilled water circuits
The Cobra cyclones, complete with CRS dirt collection units have now been tested and installed at a number of large City Council housing complexes, including Lambeth, Wandsworth, Chichester & Leicester, where continuous problems associated with Boiler Sludge & solids have been eliminated.
‘When the Cobra CRS dirt collection system is deployed in the installation – you can actually show the customer how much Sludge and solids are continually being pulled out of the Circuit’ says Ian Field – Waterwise Sales Manager.
Indeed, the Hotel industry amongst others have also taken advantage of this technology, to easily protect their heating & Chilled water systems & there are dozens of installations running across the UK within many different types of commercial buildings.
For a very modest investment, huge service cost savings are instantly gained, as the Cobra continuously cleans & protects the Boiler or chilled water installation from Sludge and scale debris, without the need for any further service or maintenance to the unit.
