PRODUCT DESCRIPTION
PROUCT DESCRIPTION
The PrecisionAir WS series is designed to
control the internal temperature of an enclosure.
by removing dissipated heat from inside the
structure and is designed to maintain accurate
temperatures for electronic equipment.
IMPORTANT
Dantherm Cooling Inc. recommends that the
cooling system should run continuously.
FUNCTIONALITY
The illustration below shows the airflow of the
air conditioner. The two air flows (internal/
external) operate separately. External air is
only used to cool down the condenser which
dissipates the heat absorbed by the indoor
evaporator. The air flows are not mixed.
INTERNAL AIR FLOW
Warm, internal air is drawn into the unit by the
internal evaporator fan. The air is then pushed
through the evaporator, and then released into
the enclosure through the evaporator opening.

condenser fan, and then routed through the
condenser, where it is cooled. After passing
through the condenser, the air is returned to the
external environment.
