Media Coating 

On this page we will uncover the edge coating option for media, what it is and when it is used. You will find videos, downloads. and information regarding edge coated media.

Coating is an option when purchasing evaporative cooling media. Here at ATEC we are wholesalers for the top brands of media on the market, we offer Munters and KUUL products. Both manufacturers offer a coated option:

-Munters offers MIT-edg for their cellulose paper media and they offer TUF-edg for their fiberglass media.


-Kuul® offers their DuraPro for their cellulose paper media.

What is coating and why is it

sometimes used?

This coating on the media is dipped onto a side of a regular piece of media. For most cellulose paper media it is a black color coating and for the fiberglass media is is a light tan color. The side with the coating is more rough and hard. This coating is meant to help with increased durability. When installed it is placed in the unit facing outward towards the elements. When is comes to evaporative cooling and humidification there are hundreds, if not thousands, of applications. Each application is different and exposure to different elements. Sometimes an application will receive increased sun exposure, or weather in general. Perhaps a certain exposure will have an increased exposure to chemical or algae buildup. That is when this engineered coating comes in handy, it can help give longer life and efficiency to your media. When placed to face the elements this engineered coating will withstand a little more of abuse against the elements than regular media. 

Of course not every application needs this coated media but thanks to our manufacturers it is a great option to help prolong the life of your media, especially for those more exposed applications. Both regular media and coated media are equally efficient in their use but sometimes you may need that little extra covering. 

Bellow you will find a diagram of how coated media is installed into a unit.

Distribution Pad:


There is one more piece of media that has coating on it, it is a small and sometimes overlooked piece. This piece is called Distribution Pad. This small piece is long and only about 2-3 inches deep. This long thin piece is also coated to add durability. In many cases we have seen this piece get thrown away mistakenly, if you do get this small coated piece in your order don't throw it out. When placed on top of your bank of media it helps to evenly distribute water over your media adding to the efficiency and wet out of your media. It is a great tool to help add to your cooling experience.
