Connection systems

Tubo isolato in EPE

Insulated round EPE pipe

Insulated pipe in polyethylene foam (EPE) available in diameters 125, 160 and 180 mm (thickness 16 mm/30 kg/m³).
Simple and rapid installation with a perfect seal, it is used to connect the fan unit to the outside to enable the flow of inbound and outbound air.
Ideal for controlled mechanical ventilation plants, thanks to the insulation that reduces heat loss avoiding the formation of condensation.

HRV bare flex hose

Flexible duct available in diameters 127, 160, 180 and 203 mm, made from additive polyolefin resin film, antibacterial and anti-mould and spiral in spring steel wire.
Suitable for controlled mechanical ventilation and air conditioning systems.

Tubo Flex VMC nudo
Tubo Flex VMC isolato

HRV insulated flex hose

Flexible duct available in diameters 127, 160, 180 and 203 mm, made from additive polyolefin resin film, antibacterial and anti-mould and spiral in spring steel wire.
Thermally insulating cover in polyester fibre (thickness 25 mm/16 kg/m3). Exterior protection in aluminate film (flame retardant). The robust thermo-bonded polyester fibre avoids dispersion of the microfibers during the passage of air thus remaining intact over time.
Suitable for controlled mechanical ventilation and air conditioning.
Reduction of condensation and heat loss.

flex antibatterico nudo

HRV insulated Al Phon flex hose

Flexible duct available in diameters 127, 160, 180 and 203 mm, made with a wall in AL/PET/AL
(aluminium/polyester/aluminium) that is micro perforated to reduce the noise of the air, and spiral in spring steel wire.  Thermally insulating cover in polyester fibre (thickness 25 mm/16 kg/m3).
The robust thermo-bonded polyester fibre avoids dispersion of the microfibers during the passage of air thus remaining intact over time.
Exterior protection in aluminate polyolefin film (flame-retardant).
Ideal for controlled mechanical ventilation and air conditioning.
Reduction of condensation and heat loss.

Ariatube: tubo tondo corrugato per VMC

Ariatube: HRV round corrugated pipe

Developed in collaboration with Sanitized, a Swiss company and world leader in the production of antimicrobial and antibacterial materials, guarantees maximum performance and service life of HRV plants.
Compliance to regulations has been certified by the German hygiene institute HY.

  • Available in diameters 63, 75 and 90 mm.
  • Prevents the onset of allergies and asthma.
  • Guarantees a reduction of over 99% of the bacteria commonly present on the internal surface of pipes.
  • Prevents the formation of bacteria and fungi.
  • Prevents the onset of bad odours thanks to the use of zinc pyrithione, biocidal active ingredient.

ariatube

HRV oval corrugated pipe

Corrugated semi-rigid oval pipe made of high density polyethylene, antibacterial and antistatic.
Available in sizes 50x102 and 60x132 mm.

The radial system allows less pressure loss as compared with traditional systems and the mechanical connections ensure seal and a clean, homogenous and quality installation.
