Deaerators and dirt separators

In untreated systems, air may cause problems such as fl ow interruptions or even a complete system breakdown. Dirt consists mainly of magnetite, that can accumulate wherever a magnetic field is present. In valves or heat exchangers, pipes, radiators, pumps and calorimeters. Next to costs associated with repairs, parts and downtime, contamination also leads to reduced system performance and, therefore, higher energy costs. Spirotech offers an extensive range of SpiroCombi deaerators/dirt separators, especially designed for the simultaneous removal of air and dirt. These remove air, microbubbles and dirt particles from system water continuously.
