Updated: Sep 8, 2020

In this blog we will share some tips for media care and maintenance. Proper care of your media can help increase the lifespan of your evaporative cooling media as well are your equipment. We all like saving money and constant replacement can get expensive, with some steps of proper media care you can help prolong the life of your media.

There are many applications

First and foremost, it is important to remember that the media will respond differently in different applications. Some applications are harsher and harder on your pad than others. The general rule for media replacement is about every 3-7 years. However, that is in no way the exact timeline because of the wide range of applications which is so diverse. No matter your application there are still tips to help you save money on media replacement.

Regular cleaning

The biggest way you can prolong the life of your media is by taking it out and cleaning it every so often, especially during seasonal startup, mid-season check, and shutdown. Taking your media out to clean it and wash it will help give you a fresh look at your equipment and help you see how your media is doing and if replacement is necessary. During a regular cleaning you can even switch around pieces, this can help even out the wear on the media. Just like with any other equipment regular checks and cleaning can help with longevity and overall cost. Evaporative cooling media is a filter, there is lots of dust, dirt, hair, and other things that get caught in the media, regular cleaning will keep the media working at full capacity.

Give media time to dry out

Once you give the media a nice washing you can also give it a chance to dry out when possible. Anytime you can give your media a chance to dry out every so often is a good thing. As mentioned above different applications will have different needs, but the majority of the time you usually have a chance to let things dry out a bit before you start it back up. Giving the media a chance to dry out helps support the integrity of the media and helps keep the media from breaking down faster. An easy way is to turn off the water source, and keep your fans running.  This allows the media to dry quickly, so you can get your unit back up and running in an hour or two. 

Check your water

One big thing that causes media clogging and deterioration is water quality. We get a lot of water questions regarding the media and we do have some tips that help there as well. It is best to not treat your water with chemicals because chemicals can break down your media and make it mushy. Chemicals and other water treatments will shorten the media and shorten the lifespan. Soft water does a similar thing to media and can lead to faster breakdown of the media. Hard water is usually the least harmful to the media but does sometimes end in buildup. We do offer hard water tablets from the manufactures that can help with hard water. In general, the best tips we give when it comes to water is a repeat of the previous sections, clean your media often, and give the media a chance to dry out every so often. Another big tip when you are drying out your media is to dump your sump. This is extremely helpful in hard water conditions to reduce mineralization. Water plays the biggest role in your media lifespan.

Obey proper season startup and shutdown tips

It is impotent to properly startup and shutdown your systems during seasonal changes. Not only does that help prolong the life of your media but it also prolongs the life of your equipment as well. During seasonal startup or shutdown, it is a great time to look at the bigger picture of your overall equipment. Here are some of the tips and resources for seasonal startup and shutdown:

-Take your media out

-Wash the dirt, dust, grime, etc. off your media

-Let it dry out really well before replacing it into the equipment

-Clean out your equipment

-Check all the moving parts; sumps, pumps, sprayers, etc.

-Clean out the spraying headers (they do not always get a lot of attention).

-Do an overall check before you put the media back in and startup (or shutdown)

Replace when needed

Make sure you always keep an eye on media and replacement needs. Prolonging media replacement can result in loss of money and long-term equipment damage. Some things to look for in media replacement is soggy or sagging media, media that is rock hard, media that smells bad, or media that just looks worn down. Those are indicators that the media may need to be replaced. You can always reach out to us here at ATEC for questions on media replacement.
