Closed Loop Filtration Systems

Closed Loop Filtration Systems: Safeguard Your Water Circuits

Closed-loop water circuits, while vital for various industrial processes, are susceptible to contamination from dissolved and suspended solids generated by corrosion of pipework and components. PureTec's UltraStream filtration systems offer a proactive solution, protecting your equipment and ensuring optimal performance.

The Challenges of Closed Loop Filtration systems

Corrosion and debris buildup within closed-loop systems can lead to:

• Reduced heat transfer efficiency in heat exchangers

• Blockages and system imbalances

• Increased wear and tear on pumps and valves

• Decreased control valve performance

• Costly downtime and repairs

The UltraStream System Solution

Our conventional side-stream filtration systems, designed in accordance with Building Services Research and Information Association (BSRIA) guidelines, effectively remove suspended solids and biomass from your closed-loop circuits.

• Targeted Filtration: PureTec's CF Series filter housings, incorporating PureDepth filter cartridges, efficiently remove contaminants from a portion of the main flow (typically 5-15%), ensuring continuous system protection.

• Customised Solutions: We offer both "off the shelf" units and bespoke designs to cater to your specific system requirements and pressure conditions.

• Progressive Clean-up: PureDepth filters are available in various ratings, allowing for structured and progressive cleaning of your fluid.

• Continuous Operation: For critical applications, our PureStream SFU fully boosted pump units ensure uninterrupted filtration.

Applications of UltraStream:

UltraStream systems are ideal for various closed-loop applications:

• Condensate Systems

• Fan Coil Systems

• Plate Heat Exchanger Circuits

• Upgraded Boiler Systems

• Water, Glycol, and Brine Cleaning Filtration Systems

Benefits

• Protect Against Corrosion & Debris: Prevent costly damage and extend equipment lifespan.

• Enhance System Efficiency: Maintain optimal heat transfer and flow rates.

• Reduce Downtime: Minimise unplanned maintenance and repairs.

• Improve Control Valve Performance: Ensure accurate and responsive system control.

How Does It Work?

Where there is positive pressure of 2barg +, a flow of water is taken from the suction side of the pump and passed through a PureTec Stainless Steel CF Series filter housing incorporating PureDepth filter cartridges and returned to pressure side of the pump. PureTec ‘CF’ and PureStream SFU series filtration units are designed for side-stream filtration of closed loop systems to reduce overall contamination.

The use of side-stream units is recommended by the Building Services Research and Information Association for the initial clean up and for ongoing protection of pipework systems. PureDepth filters are available in a wide range of absolute and nominal ratings so that the removal efficiency can be adjusted to enable structured and progressive clean-up can of the fluid. Where continuous operation is required a PureTec PureStream SFU fully boosted pump unit can be installed to the system.
