Alius Duoflex isolated tube DN40 6,5 mm

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

Fire safety

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