SpiroTrap Steel
SpiroTrap Steel Dirt Separators – Heavy-Duty Protection for Large Systems
In large residential buildings, commercial properties, industrial plants, and district heating networks, system reliability is critical. Steel SpiroTrap dirt separators are designed for demanding high-flow applications where contaminants such as welding residues, sand, and magnetite can cause severe damage and costly downtime.
Manufactured from robust carbon steel, these units ensure clean system fluid and optimal flow conditions even in the most challenging environments.
Key Benefits
- Maximizes system efficiency: Removes particles down to approx. 5 µm, keeping heat exchangers and critical components clean.
- Non-clogging design: Patented Spirotube structure ensures constant low pressure drop and uninterrupted flow.
- Maintenance without downtime: Sludge can be flushed out via the drain valve while the system remains in operation.
- Long service life: Welded steel construction designed for high pressures and temperatures over decades.
SpiroTrap Magnet – Advanced Magnetite Protection
Modern high-efficiency pumps attract magnetite particles, which can quickly lead to clogging and failure. Steel SpiroTrap Magnet models incorporate an external magnetic system that directs a strong magnetic field into the flow, efficiently capturing even the finest magnetite particles.
During maintenance, the magnet is simply moved aside, allowing the collected sludge to be flushed out quickly without system shutdown.
Applications and Options
- Connections: Flanged or welded DN50–DN300, with custom sizes up to DN800
- High-flow versions available for flow velocities up to approx. 3 m/s
- Applications: Commercial buildings, hospitals, schools, district heating plants, industrial systems, and large cooling networks
