I bought filter screens for eight of my units - six rooftop units and two 150 ton air cooled chillers. What a difference it has made in both our maintenance and energy savings. With our new filter screens, we have reduced our maintenance time by over 50 percent and our energy cost has dropped by over 25%. I wish we had been aware of this great product long before now.

Due to the growing need of cooling towers around the world and in India in particular, many companies have been set up to meet the demand of such towers in various industrial applications.

Johnston Sat, 05 Mar 2011 16:16:34 +0000 http://www.cottonwoodfilters.com/?p=161#comment-3295 Coil cleaning, though an unpleasant task is critical to our operations - It takes us about 2.5 hrs. to clean our 90 Ton Intellipack Units - with 6 of these units supporting robotic welding systems, we cannot afford for the equipment to go down due to coil fouling; when cleaning the coils, we still have to take the units off-line resulting in expensive down time and lost productivity. We tried everything from window screens to roll filter media and quickly discovered that these materials though effective in stopping debris, seriously restricts air-flow and cause our equipment to trip off on high head. Last summer we tested cottonwood filter screens with quick release quarter turn fasteners on one of our units - Our rep came out and measured our equipment for proper sizing prior to ordering - WOW, what a huge difference they make. We will be purchasing filters for the rest of our equipment this season - they really do work and we are able to clean the filters in a fraction of the time it takes to clean the coils - now we simply turn off the fan and sweep the filters off, turn the fan back on and move on to the next unit - NO INTERUPTION TO PRODUCTION.

Minissota during winter. compressor stalling is a common occurance when the temperature dips below 20 degrees - which is often this time of year. When our compressor on our Trane 200 ton process chiller would stall We usually throw a plastic tarps over the coils to stop the wind from blowing through - but there is no good way to fasten it and it seems to always come loose and flap around in the wind - not to mention that a tarp looks really ugly and unprofessional. The Weather Guard is a great idea. I will be contacting you about this - I also want to talk to you about the cottonwood filter screens - but thats a whole different issue for us. James N.

Wed, 04 Nov 2009 16:55:09 +0000 http://www.cottonwoodfilters.com/?p=69#comment-8 Excellent point! We have always tried to get ready for the spring at year end maintenance time. One area we used to defer till Spring is coil Cleaning because we hated cleaning coils. After installing the Filter screens on seven RTU's it significanly reduced our overall maintenance. We simply sweep or rinse the Screens with water and we're done - coils stay clean year around. Great Product! Christopher J., HVAC Supervisor Facilities Operations Excellent point!
