The Smart, All-Natural Cooling Solution for the Environmentally
& Energy Conscious.
America’s evaporative cooling choice for years,
MasterCool®is second-to-none. Leading the industry in
providing solutions to the problems associated with con-
ventional aspen-pad coolers, MasterCool II is the smart
choice. Featuring a sleek, low profile design, a single long
lasting, high-efficiency pad for low maintenance, cooling
power and money savings, is an affordable product with
premium performance. Designed for the environmentally
and energy conscious, MasterCool uses nature’s refrig-
erant, water, to cool. Unlike air conditioners, which use
chemical refrigerants, most containing environmentally
damaging CFCs, MasterCool cools naturally … through
the evaporation of water. Built to last, MasterCool uses
the finest motors and pumps available. The efficiency of
MasterCool products means all natural, cool, clean com-
fort and lower energy bills.
COOL, CLEAN COMFORT ... NATURALLY.
