Spirax Sarco steam ejector using steam to heat water or other fluids. In operation, the steam ejector suction fluid from the annular port to mix, spray water into the heating tank . Causing the injector loop ensures sufficient mixing to avoid the difference in temperature stratification . Three injector diameter , suitable for a very wide range of applications .
There are internal / external thread , can be mounted directly on the wall of the tank smallest IN15 type , but also by pipeline access to the water tank.
IN25M and IN40M is externally threaded and butt weld type , installed with the IN15.
In the higher flow requirements , you can install two or more parallel injectors .
Main features:
- All stainless steel
- Ideal for applications in boiler feedwater heating and oxygen
- Efficient steam heated water and other fluids
- Heating , mixing and circulation - no moving parts
- Compact design - minimize noise and vibration

Installation Precautions
Injectors mounted in the lower position of the tank , preferably located in the midline , horizontal steam injection . Pipe in the tank can also be outside of the tank . Good steam pipes must be fixed to prevent vibration and stress the tank wall. Recommend the use of a suitable adhesive threaded connection .
Same caliber diameter of the injector tube , e.g. , IN25M injector using 25mm pipe. A plurality of injectors , the pipe diameter as follows :
The minimum diameter of the injector model number
2 IN15 20mm
2 IN40M 65mm
3 IN40M 80mm
Between the two injectors , or at least to ensure that the injector between the tank wall and the distance of 150mm , while the outlet of the injector should be as far away from the tank wall .
