Industrial Tank Heating: Inline Steam Injection Heater and Jet Spargers

Industrial water heating is critical to many processes within manufacturing plants. Plants require heated water at precise temperatures throughout the work day and the water needs ready to go when needed. To heat large tanks, inline heaters or tank spargers are very common options. Inline heaters can be installed into existing piping and require no additional floor space. Tank spargers are a common, simple, and inexpensive option. A typical sparger is designed with a pipe that extends into the tank with a simple nozzle that delivers steam to the tank.

ProSonix steam injection heaters are designed to improve performance over traditional heat exchangers, steam spargers, and steam eductors. Steam mixing valves and steam sparging when done incorrectly can lead to steam hammer and poor temperature control. This can lead to process upsets and limits production.

ProSonix offers two solutions for industrial tank heating: the PSX I Series inline steam injection heater and the PSX J Series Tank Sparger. Both deliver sonic velocity to the fluid which supplies a thoroughly heated fluid that is ready to be used instantaneously throughout the facility.

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.

ProSonix steam injection heaters utilize internally modulated steam control to precisely deliver the appropriate mass flow of steam. This design offers a precise method of steam control and eliminates steam hammer. Watch the video to learn more about the ProSonix proven solution for heat processing with steam injection.


Common Steam Injection Heating Applications
for Tank Heating & Water Heating

Hi-Flow Tank Fill

Many processing plants require 24 hour available hot water supply to support plant operations. Often times the surge in hot water needs can vary and a hot water surge tank is required to stabilize the demand. A PSX heater can help to maintain on demand ready hot water.

Manual Tank Fill Water Heating

Making small batches of chemical solutions requires hot water to complete the batch, staging hot water for on demand cleaning situations or other process needs can be difficult to do because of time required to start heating system. ProSonix can provide a manual system controlled locally by a system operator to address these needs.

Tank Sparging

Tank heating is very common for most process plants. Hot water staged for specific use or continuous hot water supply is important for maintaining production and CIP cleaning. ProSonix J-Series tank mount jet sparger is designed to handle steam pressure from 15 – 300 psig.
