EVAPORATOR IOM
Coil Types
1. Heatcraft’s model EN evaporator is used for applications where capacity control is not
required. Single or multiple distributors are available depending on the number of cir-
cuits required. Model EN evaporators utilize dual suction connections when multiple
distributors are used.
2. Face control (model EF) is another evaporator coil option offered by Heatcraft. Face
control is the simplest form of capacity control. Type EF coils are normally furnished
with two distributors and two suction connections offering 50% capacity reduction ca-
pabilities.
3. Heatcraft offers a row control (ER) option for six row evaporators. These coils are split
two rows and four rows which offer approximately a 50% capacity reduction.
4. Heatcraft’s EJ coils come with interlaced circuiting. This form of capacity control uti-
lizes two distributors with each feeding every other tube in the first row of the coil. Each
distributor has a separate suction connection.
5. For applications that require face control and interlaced circuits, Heatcraft offers evapo-
rator model EK. Interlaced face control utilizes four distributors and four suction con-
nections.
