The MicroZone generates Ozone and injects it into the coolant to kill bacteria and mold to a level below the nuisance level. It manages the bacteria and mold levels but does not give a 100% kill. Ozone is generated electrically and therefore adds no chemicals into the treated coolant.

Ozone is produced through the most common method, corona discharge.

No. Customers have also found success in low-volume chemical sampling or biofuel sampling.

In the quantities needed for coolant control, it has no noticeable odor or color. It is not irritating to humans or equipment. It acts quickly and efficiently and leaves no chemical by-products except oxygen. In contrast, biocides can lower pH, cause salt build ups that can require dumping, and if overused, can cause dermatitis. While chlorine and other forms of biocides form thousands of extremely toxic by-products, ozone forms virtually none. Ozone is easier and safer to handle than biocides because Ozone is generated on site, this eliminates transportation hazards.

The ozone or active air disperses through the coolant oxidizing bacteria and mold. The ozone is used up at point of contact. The Ozone instantly oxidizes any organic material that it comes in contact with and then returns to its original form: oxygen. The result of this process is an oxygen rich environment which is fatal to odor forming bacteria while not causing damage to the coolant itself. A healthy environment is achieved.

One of the keys to the successful use of ozone is that it must be diffused properly within the coolant system. Ozone at the levels we use is safe. It goes after the fungus, yeast, mold, and bacteria. We have also found that with the microscopic bubbles diffused in the solution acts somewhat like an dissolved air floatation system and helps with the removal of very fine dispersed tramp oil droplets that otherwise may be missed on one pass through a traditional coalescer.

Yes, Ozone is one of the most effective, complete bactericides in nature and kills virtually all know forms of viruses in water.

OSHA limits ozone in the workplace to 0.1 ppm over an 8 hour day. If the Microzone 300 is properly installed, there will be very little off gas. Any off gas that may be generated will be diluted by the air in the room. It would require very extreme conditions to exceed OSHA limits.

Retired Product Support

Accurate Tool Co was acquired by Sentry Equuipment in 2023. The product line was renamed to Sentry Saf-T-Vise and is still available here.

You can see the full list of Accurate Tool Co discontinued products and their replacements here.

The Sentry TRB Sample Cooler has been replaced by the Sentry TRW Sample Cooler

If you have additional questions regarding your TRB Sample Cooler, please contact us.

  1. The Sentry MG Automatic Strip Sampler has been discontinued. Comparable products include the Sentry D2 Automatic Sampler and the Sentry RX Automatic Sampler.
  2. If you have any additional questions regarding your MG Automatic Sampler, please contact us.

The purpose of this consolidation is to offer the widest range of steam and water sample conditioning equipment and accessories available under one brand while making the selection, application, service and support of the equipment easier for the end user. The discontinuation will result in less variability in overlapping components, making system maintenance, repair and replacement much easier.

Sentry offers more options and configurations than Waters Equipment.
