Coil Types

Distributing

McQuay models JA, RA and DA jet-tube steam distributing
coils (Figure 1) are excellent for any general purpose heating
application. With the superior freeze resistance provided by
the tube-with-in-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

McQuay model SA steam coils (Figure 1) are 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
connection insures proper steam distribution. Model HA
utilizes cupro-nickel, carbon steel and stainless steel tubing for
high-pressure construction.
