SpiroCombi deaerators/dirt separators are designed for the simultaneous removal of air and dirt from water systems. These remove air, microbubbles and dirt particles from system water continuously.

In untreated heating and cooling systems, air causes problems such as flow interruptions or even complete system failure. Dirt consists mainly of magnetite, that can accumulate wherever a magnetic field is present, such as 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.

Benefits of the SpiroCombi air deaerator & dirt separator

  • Combined separation system - removes circulating air and microbubbles effectively
  • Improve cost control and energy efficiency
  • Very small particles, from 5 μm (= 0.005 mm), are separated and removed
  • Dirt can be discharged while the system is in operation
  • Constant low pressure drop
  • Exceptional guarantee

The positioning of the SpiroCombi in your system

The SpiroCombi should preferably be installed at the hottest point in the system. For a heating system, this is the point where the system water leaves the heater. In a cooling system, it should be installed in the return line, just before it enters the cooler.

Innovative dirt separation

Our experts have improved the dry pocket of the magnetic dirt separator in the steel SpiroTrap and SpiroCombi units. As a result, these steel magnetic dirt separators are easier to maintain. The new magnetic dirt separators automatically extract (magnetic) dirt from system water in cooling and heating systems to prevent the yield of these systems to decline over their service life.
