Continuously investing in innovation, WEG's philosophy is to develop high performance products and efficient solutions in order to offer ideal solutions to its customers. Among them is Klabin, the largest producer and exporter of packaging paper in Brazil. 

More efficient motor in the lime furnace

Aiming at ensuring better results for its production process, Klabin purchased a 125 HP WEG W22 Magnet motor in October 2019 to replace the DC drive of the lime furnace. 

The lime furnace burns the lime mud generated in the pulp production process and turns it into lime, used in the production of the white liquor, which in turn is used for cooking wood in the digester and for making pulp. As this machinery requires attention from the maintenance teams, DC motors are not usually the preferred option due to the high inertia of the load at the start and in operation. However, the change was carried out successfully and the motor has obtained excellent performance rates. 

W22 Magnet: the best performance rate on the market

The high efficiency W22 Magnet motors have permanent magnets, thus ensuring advantages such as robustness, high performance and higher power density per frame. Driven by WEG CFW11 frequency inverter, they provide constant torque and a wide speed range, operating even at low speeds with efficiency levels above induction motors, without requiring forced ventilation. Ideal to drive paper machines, replace DC drives and solve applications where speed variation is required.

More energy efficiency for the paper and pulp industry

Energy efficiency cases like this, which promote the replacement of DC motors with high efficiency permanent magnet motors, prove that the return on investment makes good business sense, both in the application and in the selection and acquisition of the equipment, which makes them saving both money and energy in challenging times.

For Klabin, this acquisition enabled greater productivity due to the increase in the machine availability and the equipment energy efficiency. According to analysis made since the motor acquisition in October 2019, there has also been a reduction in energy consumption, exceeding the project expectations.

WEG, recognized for its energy efficiency solutions for various industrial applications, offers the market several combinations of high performance products to bring more innovation and technology for industrial processes worldwide, building solid relationships with large companies such as Klabin.
