In a context where energy efficiency and sustainability are shaping the air conditioning sector, choosing the right components for an installation is more important than ever. The TWIST O2B ACB range from TUCAI was created precisely to meet this requirement: to offer technical solutions that guarantee durability, performance and safety in both aerothermal systems and closed heating circuits .
What does O2B achieve? A technology that protects the installation
The TWIST O2B ACB range incorporates a three-layer structure with an oxygen barrier (EVOH) . This technology prevents oxygen from the air from penetrating the hydraulic circuit, drastically reducing oxidation in boiler installations, heat pumps, water heaters, and other heating systems.
The result is a cleaner and more efficient system , with less sludge and mud formation , a significantly longer lifespan, and less maintenance required.
Furthermore, its flexible and robust design simplifies assembly and reduces installation times compared to metallic alternatives such as copper or corrugated stainless steel. The installer not only gains agility, but also avoids complex joints and minimizes potential leak points .
TUCAI offers two solutions depending on the flow rate requirement and adapted to different needs:
- SUPER TWIST O2B ACB (DN13) Designed for domestic applications such as water heaters and boilers.
- EXTRA TWIST O2B ACB (DN19-DN50) Intended for larger installations such as heat pumps.
Both share the same principle: reliability and sustained performance in demanding environments, even in humid or highly condensed areas.
What are the benefits of the ACB? Safety and prevention
Beyond technical performance, TWIST O2B ACB provides a key added value: safety .
According to recent data from ICEA (Cooperative Research between Insurance Entities and Pension Funds) , 38.2% of home insurance claims in Spain during 2024 were due to water damage — breaks, leaks or bursts of pipes and hoses. In economic terms, they represented 42.4% of the total amount paid by insurers.
These data confirm a reality: prevention begins with a reliable installation . The impact is direct, resulting in fewer accidents, lower repair costs, and a more satisfactory experience for the end user.
That’s why TUCAI is the ideal choice for air conditioning installations: with TWIST O2B ACB, safety, efficiency and water quality are fully guaranteed.
