On start up the steam plant is likely to be full or air, which is a powerful barrier to heat transfer and must be removed to ensure efficient operation.

Spirax Sarco thermostatic air vents open to air and gases but shut against steam.

The presence of air in liquid lines can also cause noise, corrosion and increased maintenance costs, and air locks which inhibit the operation of the system. Air is also a very real barrier to heat transfer efficiency in liquid systems.

Spirax Sarco air vents for liquid systems open to air and gases and close tightly against liquids.

  • Ensure efficient operation and maintain process performance
  • Prevent air locks
  • Prevent corrosion
  • Reduce maintenance costs
