The Case

Stebbing Studios is the largest CD/DVD manufacturing plant in New Zealand and is equipped with the most recent state-of-the-art technology. It is a successful business which presses CD’s and DVD’s around the clock working 24 hours a day, 7 days a week.
Operational downtime was both unwelcome and costly in terms of lost production but had become a problem owing to the dissolved salt content in the water being used by the Company in its die-cooling process.
Water passing through the atmospheric cooling tower evaporated causing the salt content in the remainder to increase to a level where it was damaging and fouling the dies. A reverse osmosis application in use was not adequate for the level of the problem and help from Distech was sought.

The solution was the installation of a Distech D50 through which all the cooling tower water passes. Water free from dissolved salts and metals is now used for cooling and downtime is no longer a problem.

The studio also no longer has to purchase distilled water for production use as well as this is now available on site.

The use of distilled water has also cleaned out scaling from the existing cooling system and it is operating more efficiently.


It is also estimated that the lifespan of the cooling tower system has been extended from two years to ten years.
