DESCRIPTION
Air-Cooled Direct Expansion
The
Ecosaire
®
unit operates its refrigeration system as needed to
control room conditions.
Heat is transported via refrigerant-vapor flow to an outdoor air-cooled
condenser. The refrigerant liquifies in the condenser and returns to the
Ecosaire
®
unit.
Outdoor condensers
are rated for 95°F (35°C) ambient with optional
models available for higher or lower ambient temperatures. They are
constructed of copper tubes and aluminum fins. A factory-wired control
panel is provided for field connection. Fan cycling and pressure-
actuated fan speed control maintain head pressure of either compressor
down to -20°F (-29°C). Optional flood-back controls are available for
either 30°F (-34°C) or -40°F (-40°C) operation.
See
Installation - Piping
for details.
Water-Cooled Direct Expansion
The
Ecosaire
®
unit operates its refrigeration system as
needed to control room conditions.
Heat is transported via refrigerant-vapor flow to an
internal water-cooled condenser. The refrigerant liquifies
in the condenser and re-circulates.
Water is pumped through the condenser to carry the
heat away. Proper flows and and temperatures of water
or other fluid must be provided by others. See
Installation - Piping
.
The cooling water entering the unit must have minimum
temperature of 65°F (18°C). Contact the factory for lower
temperatures.
