    In areas with high humidity, condensation problems often occur in chilled water pipelines of central cooling systems. The condensation does not only damage ceiling, carpet and other furniture, but also waste energy by higher heat gain to the chilled water pipes.
    Aeroflex Closed Cell Insulation has been widely used in chilled water pipelines due to the following superior characteristics:

  • Very low water absorption.
  • Low and very stable thermal conductivity(K. Value)
  • Non-polar polymer base: high water and moisture resistance.
  • Universal Smoke and Flammability Proof Standards.
  • Flexibility: quick and easy installation.
  • Neat appearance.
Low thermal conductivity, great resistance to vapor penetration and water absorption, Aeroflex is widely used in chilled water cooling systems.

Flame resistance, flexibility and easy installation makes Aeroflex a very economical insulation material for high standard buildings.

WATER VAPOR PERMEABILITY
Note :
This average water vapor permeability data is based on products without vapor barrier.
Aeroflex : The closed cell structure density 4 - 6lbs./cubic ft
Polyurethane Foam : The semi closed cell structure density 2 - 4lbs./cubic ft
Polystylene Foam : The interconnecting cell structure density 1 - 2lbs./cubic ft
Fiberglass : The open cell structure density 2 - 4lbs./cubic ft
Note :
Service Time largely depends on humidity, temperature and workmanship. Under high humidity of tropical area, the low water vapor transmission is a very important factor for thermal insulation in chilled water pipeline to maintain stable thermal conductivity (K. value) during service. Condensation problem will occur when the K.Value of the insulation increases and the surface temperature of insulation drops below DEW POINT. This happens in insulations with high water vapor transmission. (average K.value of water vapor is approx. 4 BTU. in/sq. ft hr °F)
