DIRTMAG®: Magnetic Attaction - Caleffi


Magnetic dirt separator DIRTMAG® - 5463 and 5468 series

In air conditioning systems, the circulation of water containing impurities may result in rapid wear and damage to circuit components such as pumps and control valves. It also causes blockages in heat exchangers, heating elements and pipes, resulting in lower thermal efficiency of the system.

The DIRTMAG® dirt separator separates off these impurities, which are mainly made up of particles of sand and rust, but even more importantly, it is highly effective in attracting ferrous impurities. The impurities are collected in a large collection chamber that requires low frequency cleaning procedures, from which they can be removed even while the system is in operation.

The DIRTMAG® dirt separator, thanks to the multiple passage of the medium, is capable of efficiently removing even the smallest particles, with extremely limited head loss. To make the separation principle effective and keep head losses as low as possible, the flow speed of the thermal medium is slowed down by the geometrical characteristics of the body and the internal mesh element.

Why should you install a DIRTMAG® dirt separator?  

In addition to the benefits of the solutions with traditional dirt separators, they offer the following extra advantages:

  • High level of capturing ferrous particles by means of neodymium magnetic inserts contained in a easily removable external band.
  • Improved capture of non-ferrous contaminants as a result of ferrous particle drag.
  • Extremely quick and easy cleaning thanks to the magnetic band, removable from outside,  and to a wider drain cock.
  • The insulation supplied as standard, specifically designed not to interfere with cleaning procedures, makes them suitable for any type of system, assuring low heat loss and adequate anti-condensation protection.
