WINDER

Product catalog summary

Introduction
The WINDER design introduces a new generation of impellers with enhanced efficiency and reduced noise levels. This is achieved through three key innovations: sickle-shaped blades for improved performance, winglets to minimize turbulence, and a serrated profile to lower sound levels.

Specifications
The SWC blade offers superior airflow and pressure performance compared to traditional designs, reducing power requirements and sound levels by approximately 15%. The impellers are applicable across the axial product range starting from a diameter of 560 mm.

Research and Development
The technical department employs Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEA) for design and application development. These tools help pre-design units to ensure mechanical resistance and fluid dynamics performance, which are then validated in the laboratory.

Acoustic Testing
WINDER utilizes advanced noise measurement technologies compliant with AMCA 300 (BS848 part 2) standards to ensure low sound levels.

Laboratory Testing
The R&D department develops and tests prototypes in-house, ensuring they meet quality expectations. Tests cover acoustic, electrical, and fluid dynamics performance, adhering to international standards such as ISO 5801:1997, BS 848-1:1980, and ANSI / AMCA 210-85:1985.

Product Range

AXIAL WINDER: Features include high-efficiency aluminum impellers, epoxy-painted grills, and motors with IP65 or IP55 protection, operating between -30°C to 70°C.
AXITUB WINDER: Similar features with galvanized steel casing and dynamically balanced impellers.
AXITUB PIROS WINDER: Includes inspection doors, three-phase motors certified to EN12101-3, and adjustable motor support.
PIROS BOX WINDER: Galvanized metal sheet box with rock wool insulation, certified motors, and adjustable motor support.

Performance and Efficiency
WINDER impellers outperform traditional ones by providing better airflow and pressure with reduced sound levels. The combination of sickle blades, winglets, and serrated profiles enhances performance while decreasing power needs.

Conclusion
WINDER impellers represent a significant advancement in fan technology, offering innovative solutions with improved efficiency and reduced environmental impact.

WINDER Impellers with higher efﬁciency and less sound level

Open the catalog to page 1

WINDER Impellers with higher efﬁciency and less sound level With the WINDER design we have developed a new blades’ generation. The SWC is the result of three different research lines. Firstly, we get higher performance due to the sickle blades, secondly, due to the winglet applied at the end of the blade we debug turbulences and thirdly, in order to reduce the sound level we designed a serrated proﬁle at the rear of the blades. The SWC blade compared with the traditional ones gets better performance in airﬂow and pressure; decreasing the power needs and sound levels about 15%. The new impeller...

Advantages WINDER impellers versus traditional ones Better performances with less sound level On this graph, we can be observed the advantages of the winder impellers versus the traditional ones. The sickle form from the blade (A) will enable better performances. If we add to the sickle blade the winglet (B) we will get a high reduction in turbulences. And ﬁnally, adding the serrated proﬁle (C) we still increasing the performance and we reduce signiﬁcantly the sound level. The combination of the winglet, the serrated proﬁle and the sickle form gets a better performance in airﬂow and pressure,...
