SCALEMASTER 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
