Steam Injector Spirax Sarco IN15, IN25M and IN40M

The Spirax Sarco IN15, IN25M, and IN40M are steam injectors, not steam traps, designed to raise the temperature of water or other liquids in tanks or vessels by injecting steam. They use a jet of steam to draw in liquid through radial ports, mix it, and distribute the heated liquid, ensuring thorough mixing and preventing temperature stratification. Below is a detailed overview based on available information:

Overview of IN15, IN25M, and IN40M Steam Injectors

• Function: These injectors are used to heat liquids in tanks by injecting steam, promoting efficient mixing and uniform temperature distribution. They are suitable for a wide range of flow rates and applications, such as heating water in industrial processes.
• Sizes and Configurations:
  • IN15: The smallest model, featuring both male and female threads for direct mounting to a tank wall from the outside or to pipework within the tank. Ideal for lower flow rates.
  • IN25M and IN40M: Larger models available with either male thread or butt-weld connections. These are typically fitted to pipework inside the tank or to a tank wall connection. They are designed for higher flow rates, and multiple units can be mounted in parallel for increased capacity.
• Applications: Used in industries requiring efficient heating of liquids, such as food and beverage, chemical processing, or other steam-based systems.
• Key Features:
  • Ensures thorough mixing to avoid temperature stratification.
  • Robust design for reliable operation in steam systems.
  • Available in different sizes to accommodate various flow requirements.
  • The IN15 is particularly versatile due to its dual-thread design for flexible installation.

Installation and Maintenance

• Installation:
  • The IN15 can be mounted directly to a tank wall or connected to internal pipework.
  • The IN25M and IN40M are typically connected to pipework within the tank or to a tank wall via male thread or butt-weld connections.
  • For higher capacities, multiple injectors can be installed in parallel.
  • Detailed installation instructions are provided in Spirax Sarco’s documentation (e.g., IM-P401-27 AB Issue 4).
• Maintenance: Regular maintenance is required to ensure optimal performance. Spirax Sarco provides fault-finding guidance and maintenance instructions in their documentation.
• Safety Information: Proper pressure equalization and safety protocols must be followed during installation and operation to ensure safe handling of steam and hot liquids.
