RefrigerationCarefully selected piping insulation is critical to the efficiency of a refrigeration system

Controlling condensation and moisture on refrigeration cold-water lines is essential for long-term thermal performance. While condensation and moisture are known as culprits in mold growth, they also have a significant impact on system efficiency as moisture degrades the performance of the insulating material.

Selecting closed-cell elastomeric foams, like AP Armaflex®, is one sure way to prevent moisture (and therefore heat gain) from invading the piping system. Not only does closed-cell foam insulation possess a low permeability rating, but it is also much less vulnerable to punctures and tears that can impair the thermal effectiveness of open cell and fibrous materials.

RefrigerationWhy is condensation a problem?

If moisture intrudes the insulating material surrounding cold-water piping, efficiency is lost. If the temperature surrounding the piping drops below the dew point, condensation will form on the pipes. The presence of moisture not only robs the system of its thermal efficiency, it provides suitable conditions for mold and mildew.

Attributes:

  • Low permeability, controls condensation

  • No additional vapor retarder needed

  • Resists growth of mold and mildew

  • Maintains thermal integrity

Armacell’s AP Armaflex foam insulation is available in tubes and continuous coils for easy installation on refrigeration cold water lines.
