Custom Desuperheaters
Desuperheaters lower the temperature of (or attemperate) a superheated steam line using a cooling water source (typically a boiler feedwater (BFW)). The superheated steam or gas is directly in contact with the cooling water or fluid. Desuperheating immediately begins the process of evaporation and absorption into the steam line. Typically, enough water will inject into the line to bring the steam temperature down to around Saturation (+/- 10°F ). However, the desuperheaters can be used to more moderately attemperate the steam to a specified final temperature if desired. This is possible because Komax desuperheaters can operate with a turndown range of up to 20:1 with proper pressure control.
The Komax custom Desuperheater utilizes a unique approach to desuperheating compared to conventional desuperheaters. The Desuperheater uses both a low-pressure spray nozzle directed upstream of the steam flow and a patented Equalizer Mixing Module. We incorporate this into all of our desuperheater designs. This mixing module design is specifically for gas/liquid mixing and can shear the water droplets (or cooling fluid droplets) to very fine sizes.
Your Best Option
Wondering just what makes the Komax Desuperheater so good? Three stages of mixing, including our patented Equalizer™ mixing module within the desuperheater. Cooling happens almost instantly as it exits the mixing module, thus it doesn’t require the extensive downstream pipe lay length required by old-school designs. In fact, it needs less space, delivers more accurate temperature control, and reduces or eliminates thermal cycling fatigue in your piping, ensuring improved safety, less wear, and downtime. This makes for quick and efficient absorption of water into the superheated steam line.
There are no moving parts, and our steam desuperheaters offer high levels of consistency. Maintenance is never an issue as the low-pressure nozzle lasts and lasts. Almost no noise or vibration can be expected, and it’s a perfect fit for limited space.
Our patented Komax Desuperheater will exceed your expectations by increasing the efficiency and effectiveness of your gas desuperheating application at a price you can afford.

Using three stages of mixing, including our patented Equalizer™ mixing module within the desuperheater. Cooling happens almost instantly as it exits the mixing module, thus it doesn’t require the extensive downstream pipe lay length required by old-school designs. In fact, it needs less space, delivers more accurate temperature control, and reduces or eliminates thermal cycling fatigue in your piping, ensuring improved safety, less wear, and downtime. This makes for quick and efficient absorption of water into the superheated steam line.
A desuperheater works by injecting a cold fluid (typically water) into a hot steam line to lower the temperature of the steam. The water that is injected typically is injected via a spray nozzle or in order to absorb into the steam line. Usually the water will be absorbed into the steam line within about 30 pipe diameters of length, but with the Komax Desuperheater, we can reduce this length to 10 diameters with the use of our Equalizer Mixing Module. The Equalizer shears the water droplets that are introduced into the steam line into a fine mist so the water is absorbed into the steam almost instantaneously.
A desuperheater can be used downstream of a boiler to reduce the steam temperature prior to being distributed to a user or process. It can also be used upstream of a turbine to reduce the temperature of the steam for safer operation for power generation. Our engineers will be able to help determine the best placement for your desuperheater within your process. Just fill out a form and we'll get your project started swiftly!
