Pick Direct Steam Injection systems are ideally suited for heating water or water miscible liquids wherever precise temperature control, energy savings and ease of installation and operation is desired.
Pick delivers hot water on demand at a precisely controlled temperature- even in difficult frequent start/stop applications. It is compact in size and can be easily installed practically anywhere in your plant. 100% heat transfer means high efficiency with energy savings up to 28% versus indirect heat exchangers.
You'll find Pick Heaters at work around the world, in every kind of industrial environment, being used for operations such as:
These case histories are but a few examples of the cost-saving benefits of Pick Heaters:
Automotive Industry Parts Washer
A Pick Heater replaces a plate heat exchanger to supply hot water for a parts washer, resulting in greatly reduced maintenance and substantial energy savings.
Steel Industry Acid Pickling
The acid pickling process, used to clean cold-rolled steel, requires an instantaneous supply of hot water a widely varying flow rates. A Pick Variable Flow Direct Steam Injection Heater meets the challenge.
Anaerobic Treatment of Organic Waste
The Pick Heater can handle large volumes of liquid with a low liquid side pressure drop, while maintaining the tight temperature control necessary in the anaerobic process.

Customers have many choices for heating water, liquids or slurries, but Direct Steam Injection (DSI) Heaters should be at the top of the list of options for these challenging applications.
When choosing a Direct Steam Injection 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.
The most common method of transferring energy with steam is indirect heat exchange, which has a significant drawback. Due to the pressure drop as the condensate exits the trap, some portion is inevitably lost to flash evaporation. As the condensate is lost, system efficiency is impacted. There is an alternative method that is ideal for high-pressure systems: direct steam injection (DSI) which achieves 100% heat transfer efficiency.
The challenges of heating fluids and providing a steady hot water supply are important to a wide range of industry types, and there are many solutions that engineers employ to meet those challenges. Not all solutions are equal, however; following a selection path designed to save up-front costs may not always be the best strategy. There are numerous factors to consider, including ones that may be less obvious.
The limits to indirect heat exchange examined in Part 1 become more significant as greater temperature or pressure is required for heat and hot water applications. In many cases, the solution for design engineers is to opt instead for direct steam injection (DSI).
Pick Heaters will be exhibiting at the upcoming 2025 Equipment, Automation, and Technology Show (EATS) for the Food & Beverage industry! Join us October 28–30 at McCormick Place in Chicago, where we’ll be showcasing our direct steam injection (DSI) heating systems at booth #2205.
