Strainers DN 200-600

TerFOM; TerFM - with magnetic inset

TerF; TerFO - with out magnetic inset

Magnetic Strainers are designed to strain contaminants in solid form from water in heating networks, heat substations and boiler rooms. Magnetic Strainers allow for proper operation of the regulators, valves , control-measuring equipments, heat exchangers, pumps and other elements of the installation. In larger networks, as well as sources of heat, you can also install the strainer as bypass filter, operating at flow 5 ÷ 8% of the nominal flow of water. The strainers provides simple installation and easy maintenance.

Special features:

• inertial strainig,
• sendimental straing,
• mechanical filtration,
• magnetic filtration,
• air separation,
• low pressure loss.

The strainers are producing in following versions:
TerFOM - made of stainless steel with the magnetic inset,
TerF - made of stainless steel,
TerFM - made of carbon steel, hot galvanised with the magnetic inset,
TerFO - made of carbon steel, hot galvanised.

Principle of operation:

In strainers water flows by inlet (2) to the barrier (8) and is directed to down of vessel to the zone of the magnetic field made by magnetic inset (9) which is mounted in connector (7) (for version TerFOM and TerFM). At the same time it comes to reducing the speed of water and separation solid impurities and air bubbles. The filter (10) at the top of the vessel is used for final purification of water and water flows to outlet (3). Sepatated air bubbles on the surface of the filter are discharged by connector (5). Separated impurities are removed by connector (6).

A characteristic of the strainers are low pressure loss (see graph hydraulic characteristics). The sequence of filtration steps, makes more than 95% impurities before the filter is retained on the magnetic stack. Final purification of water is done by the filter. Analysis of sediments from the stack of magnetic revealed that approximately 30 ÷ 40% of the substance to paramagnetics (indifferent to the impact of the magnetic force). This phenomenon paramagnetics deposition is explained by the fact of their entrainment by the magnetically active particles and the creation of agglomerates.
