Our Solutions

Processing technology for all water quality environments
Water condition management (temperature, quality, amount)
01

If the water contains a large amount of calcium and magnesium components, it is necessary to respond to the water quality, such as a water softener, an RO membrane processing unit if the water has a large amount of silica components.

02

Safe and gentle Baisabi clean, biodegradable corrosion inhibitor, keep the clean water clean.

03

Sand filter removes impurities from the medium, and automatic backwashing always cleans circulating water.

Water treatment system

Water quality analysis

Select processing method

Send pretreated water to the mold

Maintain water quality even if polluted

Improvement by system introduction

Clogged with rust and scale

​Clean water is circulated,
No rust and scale

The case study : Switching from cooling tower to waterless cooler

By solving the problems caused by the deterioration of water quality, great benefits can be obtained.

Case study

  • Temp. controller trouble repair
    →Once a month
  • Scale adhesion inside water pipe
    →about every 3-4 months
  • Oil cooler scale
    → Outside temp. is high

  • No problems with temp. controller
    →Constant temp. control
  • Stabilization of molding conditions, reduction of defective product rate
    →No piping blockage due to water quality change
