DaveThis MistCool is for "stand-still" air flow or no-wind. Because of extra fine mist at 3/4 GPH (3 quart per HOUR)...not gallon per minute.Rate of air flow rushing into radiator is so great that this MistCool can only cool about 2 or less square inch of radiator. You would need about 35 to 50 of MistCool's nozzles to cover the amount of bus's air exchange. Great if you can afford it.Sure this MistCool be great in green house or no-wind wet room.It advertise a high-pressure pump to pressurize between 58 to 106 nozzles.For outdoor....depenting areas to cover & amount of wind flow to get the job done.I have the drawing ready to post using 6 garden spray's nozzle but need to complete the "why's" & "how's" water mist will & won't work.FWIWSojourn for Christ, Jerry
Your approach is viable for dry climates, like the Southwest, but I feel it has limited use in the humid East and Midwest,. Your approach depends on the ability of the droplets to convert to vapor prior to passage through the radiator core.[/b]
I could not find any misters/systems that I thought would work including those mentioned above. So, I did a google search and found a company out in California that is in the business of making big-time misting systems for amusement parks and other applications. I called them, and talked to the tech guy and told him I was a bus guy and need help on which of their systems could help me. He told me that the owner drives a Prevost bus and that they had perfected the "misting" system on his bus. Here is the recipe according to them:1) Buy an intermittent wiper switch from JC Whitney, install it making sure it is run thru the ignition...I guess the boss had left it on running the water out of the tank. This allows you to vary the amount of mist action.2) Run copper tubing down the sides of the radiator. Drill holes in the tubing(he said use the smallist drill bit you can). 3) Position the copper pipes so that the stream/mist holes point toward the center of the radiator. I think I might try this...the only thing I'm going to do is "T" this off of my 1/2" poly tubing at the back of the bus(we have a half bath in the back) and just put a simple ball valve which I'll get one of the kids to turn on which I need it.-Brent
