ASENSI was at FinnBuild, 29 September to 1 October 2026
Thank you to everyone who visited our stand 6c2. The conversations, the questions and the selfies at the height wall were the best part of the fair for us. ASENSI is the official importer of Valsir, Fondital and Elysator. Our range covers 15 main building services systems from basement to roof. We deliver the products straight from the factories to the site.

VentilationValsirOur range includes heat-recovery ventilation units with a temperature efficiency of up to 91 %* depending on the model. Room-by-room ventilation units with heat recovery are also available.*Dry temperature efficiency stated by the manufacturer. 91 % applies to the Ariosa HV 170, Ariosa V 350 and Ariosa V Compact 150 size classes with a sensible-heat exchanger. The efficiency depends on the model, the exchanger type and the operating conditions, and it is not the same as annual efficiency.Ariosa ▸
RadiatorsFonditalAleternum composite radiators carry a warranty against manufacturing defects of up to 20 years depending on the model. The Aleternum treatment of the inner surface protects against corrosion. Correctly sized, the radiators also work with a heat pump’s 55 °C flow temperature.Aleternum B4 ▸
Water treatmentElysatorElysator has over 50 years of experience in corrosion protection. Trio .1 reduces the amount of oxygen in the heating-system water and regulates its pH without external electricity or added treatment chemicals. PUROTAP units demineralise the system’s fill and make-up water. Correctly chosen treatment and water-quality monitoring support water quality in line with the VDI 2035 guideline.Elysator and Purotap ▸

All 15 main systems: the ASENSI house ▸
Three manufacturers, one supplier
When potable-water, drainage, fire-stop, heating and water-treatment products come from one supplier, you know whom to contact. ASENSI assembles a delivery suited to the project from Valsir, Fondital and Elysator products and also helps with warranty matters. Warranties follow the manufacturers’ product-specific terms.
In the customer service portal the installer compiles the parts list with the configurator, orders the products, follows the order and gets product support from the same service.
Book a meeting
Book a meeting and we go through the products that suit your project together. The topic can be, for example, a pipe renovation, a new build or a housing company’s switch to heat-pump heating.
Films
Building services are often noticed only when something stops working. In our animated films we explain how the products work and what happens inside the wall. The product facts in the films are based on material published by the manufacturers.
The villains of our films, Noise, Haste, Greyness, Salt, and Rust and Sludge, stand for real problems on site. The stories show how the products help to solve them.
We also make short installation videos: one product and one work step at a time. They are meant to be watched on site from a phone.
The fourth character is here
The fourth character is here! Our FinnBuild 2026 contest winner, Johnny Heikkilä from Etteplan, built himself a character, and now Johnny joins Jonna, Aki and Pekka. The first job was waiting straight away. Thank you, Johnny and Etteplan, and thank you to everyone who took part!
