ARIA ADURO is a system made of a highly insulating material (expanded polystyrene) for mass air transfer to and from HRV unit.

Material used for ARIA ADURO is light and durable, and enriched with graphite makes it resistant to fungi, mold and bacteria.

The system has been designed with heat recovery ventilation for single family houses in mind and together with ARIA CONNECT semi-rigid ducting system they provide a complete air distribution system for heat recovery ventilation HEATEPEX ARIA.

The intuitive ARIA PLANNER selection software available on our website allows you to design a heat recovery system in 3 simple steps. It provides a necessary documentation and creates a list of components.



Insulated mass flow ductwork for HRV


Versatile system

3 diameters: 125 mm / 160 mm / 200 mm

ARIA ADURO is offered in 3 most popular diameters. Reducer 125/160/200 with ability to match the system to each of the 3 diameters.



Standard dimensions

ARIA ADURO fits to most of the HRV units available on the market and the dimensions are in line with traditional ventilation equipment.  Inner diamensions comply with the EN 1506:2007 standard.

Complete system

for your house

ARIA ADURO and ARIA CONNECT can be combined for a complete air distribution system for heat recovery ventilation HEATPEX ARIA.


Fast installation, high level of insulation and airtightness of the system are just some of the advantages of our solution.



OneClick technology®

Proven design

Thanks to adaptation of OneClick technology® known form ARIA CONNECT air distribution system, connecting ARIA ADURO elements together is faster and easier than ever.


ARIA ADURO elements are connected by a connector which needs be on slid on two components. Included gasket provides air tight connection, so no additional sealing methods are required.

High insulation and airtightness

ARIA ADURO is made out of light and durable material with high insulating properties – expanded polystyrene with addition of graphite, resistant to fungi, mold and bacteria.

Both the EPS and the added graphite result in increased insulating properties λ=0.029 W/mK when compared to metal ducts insulated with mineral wool. It reduces heat loss and avoids the formation of condensation.


Material and patented conection system OneClick® along with thought out contstruction of each element resulted in the highest air tightness class  – ATC1 according to EN 17192 standard. The result is confirmed by an independent laboratory. This means a three times higher air tightness than in a D class system.

High airtightness is achieved through a seamless construction of ADURO pipe and a connector with included gasket.

Durable and ultra light

- fast and easy installation

ARIA ADURO system is 9 times lighter than a traditional metal system, which greatly eases the installation. As a result, the setup is 2 times faster than with a round metal ducts.


Durable and rigid material with smooth interior wall  removes the risk of deformation of the duct during installation as well as reduces by half the pressure drop in comparison to flexible preinsulated ducts. This ensures a silent and cheaper operation.

Original mounting bracket

for quick installation

Simply attach the bracket to the surface, slide the pipe through and tighten the band.

Ultra light elements requrie a minimum number of mounting brackets.

Modularity – brackets, connected in series or parallel, can be used for routing two or more ducts next to each other.

Versality – one bracket size for all 3 diameters: 125, 160 and 200 mm.


Effortless cutting

- simple setup

Markers (every 5 cm) help cut the pipe to required length. Wall thickness of only 17 mm lets you easily cut the pipe, using a simple knife.
