60 " Vari-Cyclone Fan
with
Gossamer Wind Technology for 30% more air flow with same power
AC fans
can use 10 time the amps!
DC Ceiling Fan. The Vari-Cyclone with the new blade
design breakthrough, will outperform any other DC-powered ceiling fan
available. In tests conducted by the
Florida Solar Energy Center, the 3-blade Vari-Cyclone showed a 22.8%
increase in cubic feet per minute (CFM) over the 5-blade, 42" Vari-Fan. The
Vari-Cyclone can bring the warm air down from your high ceilings, blow a
cooling breeze and keep the air circulating on your porch, classroom,
warehouse, etc. The Vari-Cyclone will give you years of energy efficient,
trouble-free use operating at 12 or 24 VDC, mounted close to the ceiling or
installed with the 16" down rod (or use 1/2" plastic conduit). The Vari-Cyclone can be powered from a
battery bank or directly from a PV panel. The classic white body and blades
will fit almost any dιcor.
Use in residential or commercial.
Ratings: when mounted at least 8' above floor in
open room. 3-blade, on 12 volt is 60 rpm/2500 CFM, and on 24 volt is 120
rpm/3400 CFM. The 4-blade will move even more air. At 12 volt it is 53 rpm
with 3000 CFM and at 24 volt it is 110 rpm with 4100 CFM. The airfoil
blade shape will not move much air if fan is ran in reverse. Made by
RCH.
Stainless steel fan hardware for higher corrosive climates such as coastal
areas.

DC Evaporative Air Coolers |
 |
|
Solar Chill
12 or 24 volt
The Solar Chill
evaporative cooler's housing is made of stainless steel. The
efficient 6" thick wetted pad can last 5 years. The 24
has the best air flow and pressure and is be the best for use with ducts. 1 year warranty by manufacturer.
The 24 and 42" models ships by truck freight collect. The first 2 numbers of model
are Fan Diameter, second 2 numbers are voltage. Output diameter is 3/4" larger
than blade diameter. Max GPH is the maximum Gallons of water used Per
Hour.
Units can be powered by solar electric module direct but it
is normally best to run from a battery.
Sizing units: In a dry climate, use about 3 CFM
(cubic feet per minute of air moved) per square foot of space to be cooled if normally insulated with not much
solar gain. It will take more to cool a space that is poorly insulated or has
many windows on east or west sides, such as trailers or RVs. About 8000 BTU's of
cooling is produced for each gallon of water evaporated. Rates can vary from 1
to 7 gallons per hour.
Water Pumps: Water is pumped
from a reservoir to the filter and evaporation media and drains back to the
reservoir. The optional clean-out pump and timer are available to empty
reservoir daily. This reduces mineral and dirt buildup and increase media life.
The circulation pump and clean-out pump are the same pump and may be used
interchangeably. For automatic water cleanout use pump on a timer.
The optional thermostat will improve cooling performance and reduce humidity
buildup by automatically turning cooler on and off as needed. The Variable Speed
Rheostats are used to slow fan speed when less cooling or minimal noise is
preferred such as at nighttime.
