Coil Types
Distributing
Models JA, RA and DA jet-tube steam distributing coils are excellent for any general purpose heating application.
With the superior freeze resistance provided by the tube-within-a-tube construction, it is ideal for low temperature
preheating and special process applications. The construction features inner tubes with directional orifices to aid
in steam distribution and condensate removal. Model JA offers same-end supply and return connections. Model
RA offers opposite-end supply and return connections. Model DA offers dual-supply opposite-end connections for
long coils that see sub-freezing air temperatures. Models GA, TA and LA utilize cupro-nickel, carbon steel and
stainless steel tubing for high-pressure construction.
Single Tube
Model SA steam coil is designed for general purpose heating. The construction features a single tube design
with opposite-end supply and return connections. A perforated baffle located directly behind the supply connec-
tion insures proper steam distribution. Model HA utilizes cupro-nickel, carbon steel and stainless steel tubing for
high-pressure construction.
Standard Steam
Model SS steam coil features return-bend construction and same-end connections. Model SH utilizes cupro-
nickel, carbon steel and stainless steel tubing for high-pressure construction.
Note 1: Vacuum breakers and air vents should be piped to a drain or other suitable
location where discharged steam cannot lead to personal injury.
