4.Ten Strong Points of Huahai Air Duct Material

1.Thermal Insulation

Constant and  continuos in all duct sections.Special closed-cell insulation guarantees low thermal conductivity and limits the risk of condensation.

2.Friction Loss

The low number of flanges and limited surface roughness keep linear friction loss at very low levels.

3.Aritight Seal

airtightnes of HUAHAI ducts is eight times more than traditional ducts.

4.Energy Saving

Perfect thermal insulation and optimum airtight seal allow for maximum exploitation of air handing unit capacity, increasing efficiency and reducing operating costs.

5.Hygiene and Air Quality

The use of aluminum for the internal surface of ducts ensures hygienes and cleanliness.The problem of ageing of the insulation and consequent release of particles is non-existent.

6.Safety

Huahai ducts have a low participation in fire, do not drop and smokes have a reduced opacity and toxicity. Huahai air duct is in conformity with the requirements of the most restrictive international regulations.

7.Light Weight

The very light weight allows a reduction of weight on the structures,supporting points,workmanship costs and material necessary for the installations.

8.Silent Operations

The sandwich structure (aluminum-insulating material-aluminum) guarantees a good acoustic behaviour. Vibration and reverberation are stopped by the insulating material, contributing to a higher comfort in the environment where Huahai air duct is installed.

9.Duration

Ther outer aluminum coating coupled with the insulating material provides sturdiness,rigidity and good resistance to corrosion,erosion and deformation even in special applications.

10.Construction easiness

Possibility of manufacturing ducts in the work shop or directly at job site with considerable advantages on transport costs.
