Hyundai Motor, Ulsan, Korea

Installation Details
Location: A car engine manufacturing factory, Hyundai Motor Ulsan
Area: A cold water circulation pipeline for the cooling tower and the induction hardening machine
Pipe size: 100 mm
Model: Vulcan S25
Installer: Vulcan-Korea team

Scale Problems
  1. Scale problems in the pipelines and the induction hardening machine.
  2. There are 9 secondary small pipes, they had to be cleaned manually every 2-3 months

Installation of a Vulcan S25 unit:
May 21st, 2018.
Note: scale was not manually removed before the Vulcan was fitted on source pipe (see photo).
Examination of secondary piping:
November 21st, 2018

  1. Since Vulcan S25 was installed, the Hyundai Engineering Team has stopped the regular manual cleaning process.
    Observation: the flow rate with the Vulcan unit is now even higher than immediately after previous manual cleaning had been done.
  2. After Vulcan S25 had been installed for 6 months, the secondary pipes were opened: scale that had been left in piping had disappeared and all 9 secondary pipes had become clean (see photo).
    Observation: Biofilms in the cooling tower had disappeared since the Vulcan unit was installed.

Vulcan S25 was installed around 50 meter before the induction hardening machine.

There are 9 secondary small pipes with water meters. These meters were installed to make sure a stable flow rate. If the flow rate goes down, it would cause a problem of the induction hardening machine. Therefore, the pipes had to be cleaned manually every 2-3 months.
