IN15, IN25M and IN40M

Steam Injectors

Description

Available types

The IN15 is supplied with a 1⁄2" female and 1" male thread, available

in BSPT or NPT.

Options for the larger injectors are shown below:

Spirax Sarco steam injectors use steam to raise the temperature

of water or other liquids. They work by using a jet of steam to draw

in the liquid through radial ports, mix it, and distribute the heated

liquid throughout the tank or vessel. The circulation induced by the

injector ensures thorough mixing and avoids temperature

stratification. Three sizes of injector are available to suit a wide

range of flowrates.

mounting to a tank wall from the outside, or to pipework within the

tank.

The IN25M and IN40M are available with either male thread or

butt-weld connection and are fitted to pipework in the tank, or to a

tank wall connection.
