Liquid and steam injector
They heat a liquid by mixing it directly with steam, with no moving parts. The 260 injector heats the contents of a tank up to 90 °C, and the 280 liquid heater heats the liquid flowing through a pipe while also raising its pressure.

Steam injectors and heaters
No moving parts: the steam mixes with the liquid until the required temperature rise is reached.
Tank · 316 stainless
260
Tubular injector that heats the liquid in a tank with live steam and recirculates it.
Sizes
DN15, DN25, and DN40
Connection
R ½″ to R 1½″ male thread
Steam
45 to 3,000 kg/h from 2 to 16 barg
Liquid
up to 90 °C
Choose it if you are heating the contents of a tank with compact equipment in 316 stainless; if you need more capacity, you can install several in parallel.
Pipe
280
Jet heater that heats the liquid flowing through a pipe and raises its pressure.
Flow rate
1,500 to 30,000 l/h of mixture
Connection
DIN PN16 flanges
Test
from 15 to 65–75 °C steam at 4 bar
Sizes
8, from no. 0 to no. 7
Choose it if the liquid flows through a pipe and you also want to gain pressure at the outlet.

What a steam injector is and how it works
A steam injector heats a liquid by introducing steam directly into it: steam and liquid mix until the required temperature rise is reached. It has no moving parts, which reduces noise and vibration.
In the 260, a 316 stainless steel tube installed horizontally at the bottom of the tank, the steam injection draws the liquid in through the holes in the tube, where it mixes with the steam. This creates constant recirculation inside the tank, ensuring good mixing and a uniform temperature. In the 280, which is mounted in the pipe, the steam passes through small angled holes in the nozzle and forms jets that propel the liquid toward a low-pressure zone and create turbulence; the liquid leaves hotter and at a higher pressure than at the inlet.
Valfonta, in Badalona since 1962, supplies this equipment and helps you choose the model, the size, and the number of injectors. If what you need is to pump or mix, see the 248 and 250 ejectors. Learn more in our article on the steam injector.
260 injector or 280 liquid heater
| 260 injector | 280 liquid heater | |
|---|---|---|
| Where it heats | At the bottom of the tank, horizontally. | In the pipe through which the liquid flows. |
| Connection | R ½″ to R 1½″ male thread. | DIN PN16 flanges. |
| Material | Entirely in 316 stainless. | WCB carbon steel or CF3M stainless. |
| Capacity | 45 to 3,000 kg/h of steam; several in parallel. | 1,500 to 30,000 l/h of mixture. |
If what you need is to pump or mix, without heating, see the 248 and 250 ejectors.
Applications
- Tank heatingLive steam at the bottom of the tank with the 260, up to 90 °C and with uniform temperature.
- Liquids in pipesIn-line heating with the 280, which also raises the liquid’s pressure.
- Barrel and drum washingHeating of the wash water for barrels, tanks, and drums with the 280.
- Frost-prone pipingInstallation of the 280 in piping where frost may form.
- Process industryThe 280 in breweries, sugar mills, dyehouses, and chemical plants.
Frequently asked questions about steam injectors
What is a steam injector?
A device with no moving parts that introduces steam directly into a liquid to heat it. The steam and the liquid mix until the required temperature rise is reached.
What is the difference between the 260 injector and the 280 liquid heater?
What temperature can the liquid be heated to?
With the 260, up to 90 °C, which is the maximum liquid temperature stated in its datasheet. With the 280, under test conditions (saturated steam at 4 bar and liquid at 1 bar), the liquid goes from 15 °C to between 65 and 75 °C.
Can several injectors be installed in the same tank?
Yes, with the 260: if you need more capacity, you can install two 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 a steam injector noisy?
On the 260, check that the suction holes and the discharge are not blocked and that the steam pressure is not too high. A free discharge, as long as possible, promotes quiet, vibration-free operation.
What information does Valfonta need to prepare a quote?
The available steam pressure, the liquid to be heated, the tank volume or the pipe flow rate, the initial and final temperatures, and the heating time. For the 280, also the liquid inlet pressure.
