Selective Descaling HP²scaledown
Evertz Selective Descaling
- Adapt to evergy descaling width
- No impact loss
- Energy saving
- External control – no piping on the spray bar
Descaling System with switchable nozzles
- 1 Medium Supply (process water)
- 2 Supply controlwater. Internal control bores, no costly piping!
- 3 Segmental exchange of weareplates.
- 4 Racks and supports are protected by special liner plates.
- 5 Top / Bottom Spray Bar & rackall stainless steel.
Intermediate zone = min.
plate width (permanent spraying)
According to plate width the nozzles in the outer zones are switched additionally
Features
- Wear reduce : the nozzles can be switched according to plate width.
- Energy saving: at approx. 225 bar @ 87 l/min = approx. 45 kW per nozzle.
- Flexible: thedesign / installation space can be adjusted accoring to customers requirements.
- Safety: external control, nopiping/ electricityon thespray bar.
- Long-lasting: theHP²scale down - systems are successful in operation for several years.
- Basic Know How: Use of reliable HP²duraseal Technology.
