Inline Heating

ProSonix Steam Injection Heating Solutions

Direct steam injection heating is the most efficient method of processing hot water, slurry and sludge. ProSonix steam injection heaters utilize high velocity steam to thoroughly mix and heat fluids. ProSonix inline heaters offer precise temperature control, easy installation and a self-cleaning design.

Advantages to Internally Modulated Steam Heating



By using internally modulated steam control, the heating process will be stabilized by assuring complete condensation and mixing of the steam. This results in fewer process upsets, more reliable heating, and fewer energy losses.

How It Works

ProSonix’ unique method of steam injection utilizes internally modulated steam control to precisely deliver the appropriate mass flow of steam for the required heating. This design offers a precise method of steam control through a choked flow control delivery of the steam. Choked flow is the phenomenon of accelerating a vapor to maximum velocity by creating a pressure differential through an engineered nozzle. By establishing choked flow, the steam mass flow can be 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.
