Description
Product Overview
Spirax Sarco IN15 is a steam injector. It uses a jet of steam to draw in liquid through radial ports, mixing and distributing the heated fluid throughout a tank to prevent temperature stratification.
Key Features
- Constructed from austenitic stainless steel (ASTM A351 CF3M).
- Operates without moving parts to heat, mix, and circulate fluids.
- Designed for direct mounting to a tank wall from the outside or to pipework within the tank.
- Supplied with a 1/2” female thread for steam supply and a 1” male thread for tank mounting, available in BSPT Rp (ISO 7-1) or NPT.

Installation Guidelines
Spirax Sarco IN15 must be installed horizontally at a low level in the tank, on the vertical centre line, and a minimum of 150 mm from the side of the tank. It can be mounted directly through the tank wall using its threaded connections. Steam supply pipework must be firmly anchored to prevent vibration and stress in the tank wall.
