A direct steam injection heater provides a cost-effective method to heat water and other fluids by injecting steam directly into the fluid. The direct injection heater is designed to handle a wide range of flow rates and supply hot fluids at precise temperatures.

How does a DSI work?

Direct steam injection transforms heat energy via direct contact steam condensation

  • Near-instantaneous energy (heat) transfer

  • Effectively 100% efficient – latent and sensible energy

  • Significant measurable benefits beyond energy savings

Environmental impact

  • Less boiler demand

  • Lower water usage – minimal wasted water prior to achieving the set-point temperature

  • Lower carbon footprint - minimum energy utilization to achieve a precise temperature

  • Smaller physical footprint

  • Less wastewater

  • Less cleaning and chemical usage


  • Food Processing

  • Beverage

  • Brewing

  • Dairy

  • Meat & Poultry Processing

  • Wine and Liquor

  • Oil Extraction & Refining

  • Industrial Laundry

  • Chemical Plants

  • Pulp and Paper

  • Kettle cooking

  • Power Plants

  • Pharmaceutical

  • Hospitals

  • Starch cooking

  • Clean in Place water heating

  • Pasteurizing milk

  • Cheese pasteurizing

  • Tomato paste heating

  • Baby food cooking

  • Washdown water heating

  • Sauce thickening

Sustainable benefits

  • Near-instantaneous energy (heat) transfer

  • Effectively 100% efficient

  • Energy savings / reduced steam Consumption

  • Consistent and precise discharge temperature

  • Small footprint

  • Reduced maintenance costs

  • No condensate return required

  • Handles fluids that are difficult to heat—avoids “burn-on”; highly viscous or abrasive slurries
