coilQuiet ope1. CD-H Coil is used for applications where capacity
control is not required. Single or multiple distributors are
available depending on the number of circuits required. Model CD-H
utilize dual suction connections when multiple distributors are
used.2. Face control (model CD-E) is another coil option offered by
C&D. Face control is the simplest form of capacity control.
Type CD-E coils are normally furnished with two distributors and
two suction connections offering 50% capacity reduction
capabilities.FinThe advanced rippled-corrugated CDF-H design
creates a state of continuous turbulence which effectively reduces
the boundary layer formation. The exclusive rippled edge instantly
deflects the incoming air to create initial turbulence. A
succession of corrugations across the fin depth, in conjunction
with the staggered tubes, increases the turbulating effect and
eliminates the "dead spots" behind the tubes. In this manner, the
CDF-H design establishes a high standard in heat transfer
efficiency yielding sharply increased performance. The rippled fin
edge also strengthens the fin edge and provides a pleasing overall
appearance.The need to cut operating energy expenses is met by the
CDF-E fin surface. The smoother fin design of the CDF-E surface
results in lower operating costs over the life of the
equipment.TubeCoils also feature a Patented Floating Tube Design
which eliminate refrigerant leaks at the tube sheets. Extra tubes
are added to the condenser which are expanded into the tube sheet.
These anchor tubes support the weight of the coil but are not part
of the refrigerant circuit.ConnectionsUnique hand or universal
connections can be provided. Evaporator Coil Connections: Male
sweat type. Liquid connections are brass and suction connections
are copper. Other materials available on request.TestsComplete coil
