Stainless Steel SOLAR CHILL Coolers

SOLAR CHILL 14" XP

This cooler has taken the place of our previous models 1212HP and 1612HP models long ago. This new cooler is also available in 12, 24,48 volts DC and 120 or 240 VAC as well. This 14” model can cool 300 square in the low desert and up to 800 sq feet at higher elevations on a sliding scale. If you have Air conditioning for when the humidity rises during monsoon season, this unit may even cool a 1000 square foot house, if located centrally in the floor plan. This cooler uses 38 to 52 watts on 12 or 24 volt DC, and can be run direct from a 85 to 130 watt PV panel, although we recommend deep cycle batteries for best performance. The XP in the product number stands for Extra Performance, due to the standard 8" thick wet pad, a thicker pad means cooler air! (Give us a call to upgrade your older Solar Chill Models to XP!) This 14” has dimensions of 19.5" x 21" x 24", produces an air volume of up to1150 CFM. (Cubic Feet per Minute) All of our Solar Chill models now come standard with 8" inch thick pads, and 6” or extra thick 12” pads are optional. All coolers come with a 1/4” compression type of brass float valve & drain/overflow kit with a ¾” hose bib fitting on the bottom drain. Lead times are typically 1 to 3 weeks, depending on scheduling.
