GENERAL DESCRIPTION
The Koldwave Airmaster is a portable air-cooled zone
cooler which directs cool air to specific areas or
objects through four, adjustable, four-way grilles. Many
small computer and telephone rooms, tanning bed
rooms, laboratories, factories, and numerous areas
can be cooled by its indicated cooling capacity. The
Koldwave Airmaster can also be used for back-up
cooling or as an emergency stand-by unit.
The cord-connected Koldwave Airmaster is provided
with heavy-duty casters. The swivel casters provide
handling ease for convenient relocation. This unit is
completely self-contained with the entire refrigeration
system, electrical components, condenser and
evaporator housed in an attractively-designed, painted
metal cabinet.
