How to Choose the Right Direct Steam Injection Heater for Your Needs

Pick Direct Steam Injection (DSI) Heaters can be used to heat any water-miscible liquid or slurry instantaneously where sufficient steam pressure is available. Pick Heaters offers a DSI solution for a variety of applications.

When choosing a DSI heater, there are a few factors you need to consider, including the type of liquid being heated, how much the liquid flow varies during operation or if you have a unique size or material requirements.  Once you have considered these factors, you can start to narrow down your choices. 

Pick Heaters offers a wide variety of heaters to choose from, so you are sure to find the right one for your needs.

Pick Bare DSI Heater in Water

  • Do you need a relatively constant flow of heated liquid at a precisely controlled temperature?  The Constant Flow Steam Injection Heater is ideal when the water flow is fixed or varies over a span of 3:1 turndown.  
  • Variable Flow Steam Injection Heater is used to accommodate wide variations in demand and frequent start-stop applications and is ideally suited as a central heating system for multiple use points such as plant sanitation.  Standard systems can handle 12:1 water flow turndown or are designed with dual control valves for up to 100:1 turndown.
  • The Pick Sanitary Steam Injection Heater/Cooker is the preferred choice for in-line product cooking, CIP heating or nitrogen gas injection.  The Pick SC heats or cooks any water-miscible liquid or slurry instantly on a continuous straight through basis. It can handle slurries containing bite sized particulate such as salsas or stews with particulate integrity retained!
  • Do you have wastewater, starch slurry or other water-miscible slurry to heat?  The unique design of the Pick BX Heater offers a low pressure drop, open flow pattern, key advantages over other high-velocity venturi devices and indirect heat exchangers.
  • A Pick Fabricated Heater can be designed if your flow rates, pressure rating, or material of construction fall outside Pick’s standard designs. Specifically engineered for your requirements, this solution offers the same features and benefits of our standard models.
  • Looking for a greater scope of supply?  Pick can design custom designed packaged systems with the Pick DSI heater at the heart of the system.  Pick’s system capability can also be found in skid systems using other methods of heat transfer through our PCD – Pick Custom Design solutions.   
  • Condensate mixers and Desuperheaters are additional product offerings that offer simple solutions to issues you may be facing with you steam or condensate systems.
