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

Receiving Instructions
