Industrial Case Studies

Honda Cooling Tower

Satoshi Sakanishi, Nippon Selpo Co. Ltd., Japan.

A major car manufacturer, Japan.

Cooling Tower 300HP.

Installed Units
One unit, AquaKlear Custom Model P.

Water source
Underground wells.

Chemicals for inhibiting scale and corrosion.

Because of the high cost of chemical treatment, the customer wanted to consider other treatment methods. The aim of the test was to study treatment of the cooling tower with Aquaklear, and to determine the most economical method of treatment – Aquaklear or chemicals.

Success Factor

Equipment was evaluated for several effects. The period of the test was about three and a half months.

  • Elimination of Algae.
  • Prevention of Scale.
  • Removal of Existing scale.


  • Almost all the algae on the fins were removed by AK’s performance.
  • There was not any scale or slime in heat exchanger after the installation of AquaKlear.
  • The old scale on the cooling tower fins was removed. Some scale looking like a powder was precipitated in the bottom of the basin of the cooling tower.
  • The customer concluded following this test that AquaKlear is a better treatment method than chemicals, considering also that there is no chemical pollution.
