In a sector known for extreme operating conditions, Irmãos Cioccari & Cia Ltda., a traditional limestone producer located in Caçapava do Sul (RS), began a modernization project focused on efficiency and sustainability. Since 2021, the company has been gradually replacing its older motors with W22 Super Premium IR4 models from WEG, supported by consistent investment in environmentally responsible production upgrades. Starting in 2024, this process became continuous and recurring, with approximately 30 new motors purchased annually.

IR4 Technology: up to 20% fewer losses and higher productivity

W22 Super Premium IR4 motors represent a superior standard of energy performance, offering 20% fewer losses compared to Premium (IR3) motors. This level of efficiency directly translates into significant reductions in electricity consumption, which on average accounts for 70% of industrial energy demand.

For the harsh environment of the limestone sector—characterized by heavy dust, abrasive particles, and thermal variations—the motors were specified with special IPW65 protection, a cast iron fan, epoxy sealing at the cable passage, a shutdown thermistor, and a stainless-steel threaded drain. These optional features provide mechanical strength, dust and moisture sealing, enhanced thermal protection, and extended durability.

More availability, less maintenance, and reduced environmental impact

The modernization brought direct gains in machine availability, reduction of unplanned downtime, and lower maintenance costs. Additionally, adopting higher-efficiency motors contributes to reduced CO₂ emissions, aligning with the company’s sustainability goals and ESG best practices.

The partnership between WEG and Irmãos Cioccari demonstrates how technology and energy efficiency can transform industrial performance. With motors designed for critical environments, the company achieved greater reliability, productivity, and financial sustainability.
