Local University has the following surplus for sale for $500. I live in
a dry hot summer environment and wonder if they are prone to more than
the average amount of maintenance/repair. I have about 1000 sq ft of
AIR CONDITIONER OASYS CRS 1000, INCLUDES MANUAL, DIRECT/INDIRECT AC
UNIT. 69" H X 24" W X 35" D
FWIW, There is a "new" CRS1000 currently on Ebay with a Buy It Now of
@2995. The user manual at
says the 1st stage is a "heat exchanger". No mention of a compressor.
Claims no CFCs. 2nd stage is same as Evap Cooler. Big pad with blower.
Needs water supply & drain. Has elaborate setup to minimize any mold
or algae buildup. Looks like some servicing is a 2 man job. I'd be
curious what is cost of replacement media pads ( 2 different pads).
In 25 years of running a standard Evap Cooler in Denver CO (90F-100F
summers), never had a problem with mold or too much humidity. YMMV.
