Expanded (Locked) Auxiliary Tubes:
These tubes support the coil with fins and refrigerant
carrying tubes. They do not carry refrigerant and are
tightly fitted on end supports and center supports.
Free Floating Circuited Coil Tubes:
These tubes carry refrigerant and never touch
and sheet metal (end supports and center
supports).
All condensers use the Floating Tube ™ coil design to eliminate refrigerant leaks at the tube
sheets. Additional tubes are added to the condenser coil. These tubes are expanded into the
aluminum fins and condenser tube sheets. These anchor tubes support the weight of the coil,
but are not a part of the refrigerant circuit.
The tubes in the refrigerant circuit are expanded into the fins, but “float” through oversized
holes in the tube sheets. Tube sheet leaks are virtually eliminated, since the tubes which carry
refrigerant never come in contact with the tube sheet.
All units include a limited
