Engineering

Centrifuge NCA model

High precision separator with strong centrifugal force
The best for reuse of Multi wire saw grinding fluid of silicon wafer
Centrifugal force:2200G
Comparison with conventional machine:30%UP
Removes minute particulates in coolant liquid by strong centrifugal force with industry's highest level

Features

High Efficient Separating Filtration

High efficinet separating filtration is provided by powerful separating filtration capacity, which is max revolving speed and 2200G of max cenrigugal force.

Powerful Dehydrating Performance of Sludge

Sludge is recoverable with low water content through dewatering.

Automatic Operation

The autmatic drive covers the process of separating filtration, dehydration, sludge discharging and claening.

Anti-foaming Function (Patent Pending)

The original anti-foaming function is installed as standard, and the problem of forming is reduced.

[Introduction case] Multislice of silicon wafer with fixed abrasive wire saw

Concentration change of attached tank in case with centrifugal or without centrifugal
Concentration change of attached tank in case with centrifugal or without centrifugal

*This is the result of performance test at our plant.

Introduction effect

Stabilized in lower concentration

  • Running cost reduction by reuse of liquid
  • Labor cost reduction by saving of liquid exchange
  • Stable processing is possible
