Getting ready for triple digits

Forecast is calling for 95 degrees on Saturday so we serviced Swampzilla and replaced all the H2O hoses and installed new media pads. Wont be long before we hit 100º +.
There goes the $65/month electric bill :cry:.

Bring it mother nature!
 
Be glad that you don't live in a more humid area. Swamp coolers just turn the air from muggy into more muggy with little or no cooling.
So far, I've been able to just use a whole house fan at night. Its in a back (unused) upstairs bedroom window and pulls air from the nice
cool basement (a little too cool in the winter) through the whole house. I seal up all the openings during the daytime to keep my cool.
It seldom gets above the mid to upper 70's.
 
Paco, you are cooling a very large metal building. I am curious how much water that unit consumes. Do you have any idea?
 
Alen,
The building is fully insulated with R-30 so keeping it cool is fairly easy with about 30 degree pull down. As for water use, I'm not sure as our water comes from a community well and water is inexpensive for us. SW Arizona has very low humidity levels and is ideal for swamp coolers so long as they are maintained. 12k cfm works for this size building with the scheduled ductwork. I worked outside most of my life and still do with the FD but the older I get the cooler environment I prefer during 105+ days.
 
I did have to reduce the RPM's on the unit today. The new media is less dense than OEM and had water entrainment into the dry section of the unit. I used a laser tachometer to adjust the double sheave from 306 to 248 rpm's. The bonus is an amp draw drop from 11.5 to 8.5 so might save a little on electric bill and no real airflow drop.
 
I've thought about using one in the new shop, but we only get a few days a year in the 90's, and the shop, after insulation and rock doesn't get much above 80, and is dry also. I'm sure where you are it's essential in the summer, and much nicer than mine in the winter. Looks like swampzilla should more than do the job. Cheers, Mike
 
Hi Mike,
Swampzilla has kept me in the comfort zone coming up on its third season. Keeping it close to the ground allows me to maintain and change out the water frequently. Colorado has beautiful summers for sure, but I don't like the cold white stuff much. We have Mt. Lemon about 40 minutes away, and with the 9K foot elevation, I can quickly get my snow fix.

Last year I had flocculation (dandruff as I call it) but Im sure it was due to some treatment I used on the old media pads in an effort to extend the life. I had zero issues the first season so I ruled out hard water issues. I sourced the new pads made by Munter for much less than the OEM but as mentioned I had to recalibrate the system.
Peace, Paco
 
Do you have any concerns about the extra humidity rusting any of your equipment? I'm in Phoenix and looking for a way to cool my workshop down to a tolerable level when it hits triple digits. Swamp coolers are cheaper than installing a mini-split.
