Five easy steps to protect your investment in ozone system. Part three
Modern generators nowadays are liquid cooled, and in the majority of the cases, water is used as the cooling media.
In many cases and many applications, it is possible to use process water as a cooling water source if the water temperature is suitable.
The temperature of the cooling water will influence the performance of any ozone generator on the market. In some cases, ozone generator will lose ozone output, or the production loss will be compensated by using more power, it is the matter of the philosophy of the manufacturer.
The source of the cooling water is not a critical point; it is essential to have a closed loop system, which will ensure that you have clean water through the generator.
Principally there are two types of cooling systems used:
Active chiller with a closed loop or a Traditional heat exchanger with closed loop and circulation pump.
When there is not enough cooling potential, it is just a matter of minutes before the ozone generator will shut down to prevent damage owed to the overheating, as the outcome the ozone production will stop, and your application can be at risk. Therefore, it is essential to consider the following when using a cooling skid with heat exchanger:
– Make sure that you have ball valves to be able to isolate components such as i.e., pumps on the skid for easy and fast replacement
– Make sure that the heat exchanger is positioned correctly for comfortable for an easy cleaning/rinsing
– Make sure to use duty/standby pump to ensure uptime
– Always use anticorrosion / anti-freeze in the primary loop
If you use an active chiller, please consider the redundancy in the same way as you do with the ozone equipment. We believe that it is better to use two smaller chillers than one large one or a chiller containing at least two compressors.
