Alius Duoflex isolated tube incl. cable DN25 6.5 mm grey

High energy efficiency
Alius Duoflex pipes provide the hydraulic connection between the outdoor unit and the indoor installation of heat pumps. The use of Duoflex pipes minimizes heat loss thanks to the unique properties of the aerogel insulation material.

Limited insulation thickness
The aerogel mat is nearly three times thinner than the material that is used in conventional products, while the insulation properties are of the same level. As a result, Duoflex pipes can be installed in roofs, partition walls and ventilation ducts. structures and ventilation ducts. The use of thinner insulation also reduces the space that is needed for transport and storage of the pipes.

High durability
The use of materials of the highest quality in Duoflex pipes means that the product is exceptionally durable, the insulating properties do not change over time, and the extra layer of durable PVC effectively protects against external factors, rodents, birds and UV rays.

Simplified installation
The mounting of Duoflex pipes is not complicated. The mounting flange of each pipe makes installation simple on a minimal surface area with regular screws. There are no clamps needed. Thanks to the reduced pipe diameter, they can be mounted directly under the roof tiles. Therefore no expensive, specially shaped roof tiles are needed.

Fire safety
The materials used for the production of Duoflex pipes have  an extremely high fire resistance class and are classified as non-flammable or not easily flammable.
