1. 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.
The 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.
Coils 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.
