How PSX Jet Diffuser Technology Works

The ProSonix I-Series Direct Steam Injection heater’s unique method utilizes internal steam modulation via an integral Pneumatic Actuator to accurately deliver the appropriate mass flow of steam for the required heating. This modulating design offers a precise method of steam control through a choked flow control delivery of the steam.

Steam injection heater with choked flow design delivers sonic velocity steam injection and controls the mass flow of steam through a variable area steam injector to ensure rapid mixing and condensation of the steam. This eliminates process upsets and vibration. I-series Inline Jet Diffuser utilizes 360 degree direct steam injection.

Choked flow is the phenomenon of accelerating a vapor to maximum velocity by creating a pressure differential through an engineered opening. By establishing choked flow, the steam mass flow is metered to precisely control the heating of the liquid. This produces predictable results based on position of the stem plug. Through a variable-area steam diffuser, steam flow is metered at the point where steam and liquid first contact and mix.
