Heating Convector Project

The customer is a company located in Lublin, Poland, specializing in the production of underfloor heating equipment and convection heaters.

Products and Services:

●Supplier: The company's products cover all kinds of heaters and underfloor heaters, including cross flow fans and tangential fans.
●Annual Demand: They provide one-stop installation solutions for local customers in Poland.

Annual Demand:

●30,000 to 50,000 pieces.
●Mainly Purchased Products: DC 12V, 24V aluminum alloy cross flow fans, with black electroplating on the surface (for rust prevention).

Project Case Details:

●Supplier: The low-noise tangential fan produced by Longwell is used. This cross flow fan is a star product in Longwell's ventilation fan product series, which is specifically developed and designed for applications such as floor heating and convection heaters.
●Installation Environment: The product needs to be installed in users' bedrooms, living rooms, and some commercial office spaces, with special requirements for noise and wind volume.
●Technology R&D: In view of the particularity of the application field, Longwell has specially developed a tangential fan driven by a tri-phase motor, equipped with an aviation-grade aluminum alloy shell and impeller for such situations. After years of design and testing, the product, including the DC fan variant, has been tested and validated multiple times in wind tunnel labs and BK noise labs.
●Product Performance: Under the same product size in the industry (air outlet and installation space), Longwell's DC brushless tangential fan can achieve a minimum noise of 18dBA and maintain maximum wind force at the same rotation speed, exceeding peer airflow levels. For applications requiring a DC cooling fan, this product offers unparalleled performance.
●Market Evaluation: Ultimately, a perfect solution was provided for the customers, which has received unanimous recognition and praise in the industry.
