Nozzle types overview
New Technical data (pdf, 4.34 MB)
SCALEMASTER ECO+ and MiniSCALEMASTER ECO+
- Highest impact
- New booster with integrated filter
- Additional offset angle options
- Better surface quality due to higher impact and additional offset angles
- Alternative descaling header design by new nozzle bracket
- Interchangeable with all other SCALEMASTER nozzles
SCALEMASTER HPS and MiniSCALEMASTER HPS
- Remarkable increase of impact for better descaling
- Better product surface quality due to higher impact
- Reduction of descaling water flow rate possible
- More durable tip with high mechanical strength due to window design
- Potential of energy savings due to reduced slab/strip cooling
- Interchangeable with all other SCALEMASTER nozzles
