The Importance of Maintenance

Performing regular maintenance will keep ClearWater Tech ozone systems operating at peak efficiency and will prevent most issues that may cause downtime. ClearWater Tech recommends all of our systems have preventative maintenance performed annually.

Signs that a system requires maintenance:

  • Reduced ozone output
  • Reduced airflow and vacuum readings
  • The system’s blue and white indicating media have changed color

A quick rundown of what maintenance entails*:

Ozone Generator:

  • Filter replacement
  • Check valve replacement
  • Fuse replacement
  • Reaction chamber inspection/cleaning
  • Reaction chamber o-ring replacement

EcoTex™ Ozone Laundry Equipment

The ozone generator will have one type of air preparation system, heat regenerative or an oxygen concentrator.

Air Preparation – Heat Regenerative:
(internal on /AD systems such as a CD10/AD, and or an external model such as an AD40)

  • Replacement of two medias

Air Preparation – Oxygen Concentrators:
(internal on SCL and Ae Apex systems, or external such as an OXS80)

  • Filter replacement
  • Pressure relief valve replacement
  • Compressor rebuild

Venturi Injector:

  • Check valve replacement

*The exact contents of each kit is determined by the model and revision of the system, the serial number is required to insure the proper parts are included in your kit.


Performing the maintenance is not difficult and should take less than an 1.5 hours the first time, and less time with experience. ClearWater Tech also offers an in-house repair service. Let ClearWater Tech do your maintenance for you!

How Does Ozone Get Into The Water?

Ozone gas must transfer from its natural gas state into a dissolved liquid state in order to oxidize dissolved contaminants in the water. This is probably the most important step in a successful ozone system.

There are two widely used methods to get the ozone gas entrained into the water; by diffusion or venturi methods.

Most ozone gas produced ultimately off gases to the atmosphere. In order to minimize off gassing, you must keep the gas under pressure for as long as possible for mass transfer to take place.

The venturi method is by far the best method for dissolving ozone. Water traveling through a venturi will create a pressure differential. By having a suction port at that point in pressure drop allows ozone gas to be pulled into the stream, entraining that gas into solution.

The diffusion method is far simpler, yet not as efficient in transferring gas into solution. The diffusion method entails pushing ozone gas into a body of water by the use of some air compressor. By pushing air through an ozone chamber, the gas is created and continues down through tubing into the bottom of some vessel.

To increase transfer of ozone into solution, a diffuser stone is used at the end of the ozone resistant Teflon® tubing to create maximum surface area of ozone bubbles. If you send the gas directly out of the tubing without a diffuser stone, you would have larger bubbles and less contact between water and ozone. This would create more off gassing and obviously less transfer of gas into solution.
