260 steam injector for liquids
316 stainless
Tubular 316 stainless steel injector that heats the liquid in a tank by direct steam injection, up to 90 °C. It draws in the liquid through the holes in the tube, mixes it with the steam, and creates recirculation that evens out the temperature.

What the 260 injector is used for
The 260 is a steam injector for liquids used to raise the temperature of any liquid. The steam injection draws in the liquid through the holes in the tube, where it mixes with the steam until the required temperature rise is achieved.
This suction causes constant recirculation inside the tank, which ensures good mixing and a uniform temperature. We explain it in more detail in our article on the steam injector.

- Mixing and homogenizationRecirculation ensures good mixing and a uniform temperature.
- More capacityTwo or more injectors in parallel, centered along the tank.

How the 260 injector works
- Steam inlet. Steam reaches the injector through threaded connection A.
- Suction. The steam injection draws liquid from the tank through the holes in the tube.
- Mixing. Inside the tube, the liquid mixes with the steam and its temperature rises.
- Recirculation. The mixture exits through the end of the injector and maintains constant recirculation in the tank.
260 injector installation
The datasheet includes an installation diagram with dimensions L and H from the table above.
Installation and start-up
- Position. Install the injector horizontally, at the bottom of the tank and along its length, connected directly to the pipe. No. 1 can also be mounted on the tank wall using its male thread.
- Centering. Place it centered along the tank to achieve effective recirculation and distribution.
- Unobstructed discharge. Do not install any other component in the discharge area. For quiet, vibration-free operation, dimension L should be as long as possible.
- Several injectors. Center them as well and keep 150 mm between the wall and the first injector (E) and 300 mm between injectors (F).
- Clean holes. Keep the suction holes clean. If there is excessive noise, check that the suction and discharge are not blocked and that the steam pressure is not too high.

Frequently asked questions about the 260 injector
Up to what temperature can it heat the liquid?
Up to 90 °C, which is the maximum temperature of the liquid to be heated stated in the datasheet. The steam can reach 16 barg and 200 °C.
What steam flow rate does it handle?
It depends on the size and the inlet pressure: at 2 barg, from 45 kg/h (No. 1) to 530 kg/h (No. 3); at 16 barg, from 290 kg/h to 3,000 kg/h. The full table is in the specifications.
Can several injectors be installed?
Yes. If you need more capacity, you can install 2 or more in parallel, centered in the tank, with 150 mm between the wall and the first one and 300 mm between injectors.
Why is the injector noisy?
Check that the suction holes and the discharge are not blocked and that the steam pressure is not too high. An unobstructed discharge length L as long as possible helps ensure quiet, vibration-free operation.
