Why don’t we need an air dryer with the Eclipse?
The Eclipse series was designed for residential pools (not commercial pools). Therefore, the concentrations of ozone necessary to produce a healthy bathing environment are relatively small. Air dryers or oxygen concentrators are used to remove the moisture (air dryer) and nitrogen (oxygen concentrator), thus bringing the concentration of ozone up. If we used an air dryer or oxygen concentrator on our Eclipse line, it would be too costly for residential applications, plus it would provide you with more ozone than necessary. Another reason to use an air dryer or oxygen concentrator is to remove the nitrogen and moisture which can combine causing nitric acid to form; nitric acid is typically corrosive to the equipment. However, the Eclipse corona discharge electrodes produce very little nitric acid and are designed to be resistant to nitric acid.

Why does humidity, rain, etc. cause the ozone concentration to drop?
Humidity in the air will slightly inhibit ozone production. Ozone is created when a single oxygen atom (O1) connects with an oxygen molecule (O2) to create ozone (O3). When there is moisture in the air (H2O), the single oxygen atom is more attracted to it than an oxygen molecule (O2). As a result, a small amount of H2O2 (hydrogen peroxide) is created. In this case, an air dryer or oxygen concentrator would reduce the moisture in the air, therefore creating an environment where more ozone can be created. However, using an air dryer or oxygen concentrator will significantly increase the cost and maintenance of a residential pool ozonator.

How will ozone affect pool/spa covers and vinyl liners?
Most pool covers are resistant to ozone. Studies have found that the UV rays from the sun break down the pool cover before ozone begins to discolor the cover. Spa covers, however, tend to break down quicker than pool covers and we recommend the use of an MDV to remove any potential ozone off-gas from discoloring the spa cover. Ozone, in some cases, can affect the color of vinyl pool liners so an MDV must be installed to remove ozone bubbles from contacting the liner. A common “salt and pepper” fitting should also be used to distribute water flow away from the liner.

With regard to ozone, how are “grams per hour” and“ppm” related? Which should I look at when comparingozone systems?
This is an easy question, but creates the most controversy in the ozone market. Although it is easy to compare test results, it is the test results that are not always reliable. DEL uses high-end, calibrated testing equipment to test our products, as well as our competitors’ products. When comparing a particular DEL system to a competitor’s unit, we make sure to test not only on the same day, but also at the same time of day to ensure that the testing variables are the same.

Assuming you have reliable testing data, you want to consider BOTH grams/hour and PPM, as they are definitely related. The ozone manufacturer should provide you with at least the PPM. From there, you can figure out the grams per hour. The equation is: (PPM / 6,000) x (AIR FLOW in scfh) x (.366) = grams/hour.

Now that you know grams/hour and PPM, how do they relate to residential pools and spas? There are many opinions in the industry on what the acceptable levels are. Pools and spas have many variables, such as: bather load (adults, children, pets, etc); weather (dry, humid, freezing, etc); organic materials that fall into the pool (dust, crop spray, leaves, bugs); indoor or outdoor; cover or no cover; and the list goes on… There are no set guidelines for ozone in our industry. DEL Ozone was one of the earliest ozone manufacturers in the U.S.; therefore, we have experience and testing data to guide us on recommendations for residential pools and spas. Please contact DEL if you need advice on sizing an ozone system for your application.

How does ozone work with other sanitizers?
Bromine: ozone works well with bromine. With bromine, you should keep between a 1.0PPM and 2.0PPM. Bromine works better on covered or indoor hot bodies of water, such as a spa. Some people choose to sanitize their pool with bromine.

Baquacil/Baqua Spa: ozone works well with these products. Customers with this combination seem to enjoy the quality of water, especially on spas. However, ozone seems to react with these products, causing them to be used up quicker. Therefore, your replacement costs on these products will increase. We do have one known long-time customer who has a 24-hour ozone system on his pool, he occasionally shocks with Baquashock and that’s it!

Mineral Systems: We have recommended ozone with mineral systems since 1997 and have received positive feedback from satisfied customers.

Salt Chlorinators: Ozone and salt chlorination system work very well together. Over the past several years, we have found that salt chlorinator users (that also use Eclipse ozone generators on their pools) have less maintenance and longer chlorinator cell life. That is one of the primary reasons we decided to manufacture the TrioPure, our combination Soft Water & Ozone sanitation system.

I have a 28,000 gal in ground and I am getting a bit confused on what is the right product and most efficient in corona charge.
There are a few variables that would impact my recommendation for your pool. However, let's say it's a basic pool wherein the filtration runs 10 hours a day, the pool is outdoors, the bather load is normal, and the weather is pretty average. Our Eclipse 4 or Total Eclipse 2 units go up to 25,000 gallons and you are right at the cut-off point.

If your pool runs less than 10 hours a day, the bather load is high, and the weather is hot/humid, step it up to a Total Eclipse 4.

If the pool is indoor, or runs more than 10 hours a day, you could comfortable stay with the Eclipse 4 or Total Eclipse 2, and may even be able to reduce the size to a regular Eclipse 2.

Does the Corona Discharge Unit for spa use create any AM radio interference, or any TV set interference?

I was hoping to have your email address to ask you which specific ozone generator you have. Please email me directly: jen@delozone.com with the answer to that question, then I can get the answer to your question.

I am wondering if the heat generated from a spa pump would affect the spa ozone generator mounted only inches away.
Although it may affect the spa ozone generator, the results are insignificant. They are designed to handle the heat from the spa pumps and other equipment under the spa skirt.

I have a new pool and am a rookie with the Del products. So, I have 2 questions. 1. How do I know that the Eclipse 2 is actually producing OZONE? 2. My pool company installed the Del Eclipse 2 by simply mounting the unit vertically on the wall of my house and running a plastic tube from the underside of the unit to my pool pump. They did not install the injector or any other equipment that the Del Manual shows in the installation portion. I am not sure if they even calibrated the system w/ a flow meter. Will the system work this way or should I have demand that they return to install it exactly as shown in the manual?

In Arizona, the most popular method of installing ozone generators is called "suction side." What your installer did is perfectly acceptable. You can review that particular manual if you go to our Web Library and see the Eclipse suction side manual.

I know there is a replaceable chip in the ECS units; I just want to know what happens to the old one. If it were a bulb I could understand it deteriorating over time, but this is a chip. How are my customers supposed to know when it is no longer effective other than what the owner's manual says? I want to know what makes the chip deteriorate. I know about the purple glow, tell me if there is no bulb, what deteriorates? If after replacing the chip, the ozonator still doesn't "glow" what are my options? Throw it away?

The Spa Eclipse and CDS models of ozone generators were designed with the customer in mind. When you initially plug in one of these generators, you will notice a purple glow that reaches about two thirds of the way across the chip. The customer will know when to replace the chip when the purple glow is almost gone, or gone. They may look at their ozonator once they recognize their water quality is degrading.

Generally speaking, one to two years is average for changing out a chip.

The chip starts to reduce its ozone output because as air is drawn in across the chip, any impurities are dropped out and plate out on the surface of the chip. As the deposits build up on this surface it starts to block the electrode, thus creating less ozone. The chip can be pulled out and cleaned which may prolong its life but will NOT bring it back to 100%. If after replacing the "chip" and the unit still does not work, we would recommend contacting Charlie Adams here at DEL Ozone at 1-800-676-1335 Ext. 248. He will issue an RGA # to return that unit back on and determine the cause of failure. If it is under warranty then it will be replaced.
