Condensers
Air cooled condensers are designed to reject heat from refrigerant based cooling equipment and are designed to
be installed outdoors. The condensers are self-contained in a lighweight aluminum cabinet designed for
mounting to a horizontal surface. The cabinet houses condenser coils and fan assemblies. Each condenser coil
is a copper turb, aluminum finned coil.
The capacity of the condenser is based on the rated capacity of the coil. In the case of dual circuit units, the
model number is based on the combined capacity of both coils. The coil is a closed-loop refrigerant condensing
heat exchanger in which refrigerant is continuously circulated by the pressure differential created by a
compressor.
The compressor increases refrigerant pressure to a level sufficiently high for it to be cooled and condensed into
liquid by the effect of ambient air being drawn over the condenser coil. The fans have corrosion resistant,
multi-blade impellers designed for high aerodynamic efficiency which results in lower power consumption,
lower noise levels and longer life. Each fan utilizes a direct driven motor with maintenance free bearings. The
fan motors are internally protected from overload. Fans have finger guard grilles to protect operators from
injury and keep large tools or other objects from falling into the fan.
Electrical controls are in a weather proof enclosure and isolated from the rest of the equipment. The electrical
box has a removable front access panel which is safety interlocked with the service disconnect switch,
preventing the panel from being removed when the switch is in the ON position. The switch must be turned off
to gain access to the electrical components.
