High-efficiency, 100% oil-free screw technologies designed to survive Brazil's industrial humidity and energy cost constraints.
As the industrial heart of Latin America, the state of São Paulo—spanning key hubs like the Campinas industrial belt, the ABCDR zone, and the metropolitan region—is undergoing an aggressive transition toward absolute operational efficiency and environmental compliance. Driven by stringent regulations from CETESB (Companhia Ambiental do Estado de São Paulo) and the urgent need to reduce high electricity tariffs under Brazil’s free market energy dynamics (Mercado Livre de Energia), local manufacturers can no longer rely on legacy Roots-type blowers.
Industrial facilities in São Paulo, particularly municipal and private wastewater systems (such as those managed by SABESP), food production sites (JBS, Ambev), and pharmaceutical complexes in the Ribeirão Preto or Greater São Paulo sectors, require continuous-duty, 100% oil-free compression. The presence of even trace amounts of aerosol hydrocarbons in aeration basins or pneumatic conveying channels compromises product safety, results in severe regulatory fines, and degrades membrane diffusers, creating huge operational overheads.
Why progressive manufacturing and water treatment operations across São Paulo are phasing out lobe-based displacement machinery.
Unlike Roots blowers which operate via external pressure equalization, screw blowers perform internal, progressive compression within the rotor profile. This design achieves polytropic and isentropic efficiency curves that reduce power demand by up to 35% under matching flow and pressure conditions. For a typical municipal aeration facility in São Paulo operating 24/7, this equates to significant annual energy savings.
Our direct-drive air systems feature physical separation between the compression chamber and the mechanical lubrication system. The air remains completely oil-free, eliminating the risk of downstream process contamination. This is highly critical for pharmaceutical cleanrooms and direct-contact food packaging plants across Brazil.
Integrating Permanent Magnet (PM) synchronous motors and Variable Speed Drives (VSD) allows our machines to adjust rotational speed in real time to match fluctuating demand. By avoiding hard starts and unloading cycles, our VSD systems stabilize system pressure and lower starting current spikes, protecting localized grids.
Engineered solutions solving high ambient heat, industrial condensation, and demanding regulatory issues locally.
In the biological treatment stage of facilities across São Paulo, aeration accounts for 50-70% of total energy consumption. Our low-maintenance oil-free screw blowers deliver continuous airflow to aeration tanks, ensuring biological activity is sustained efficiently. The lack of oil prevents downstream pollution of Brazil's rivers and water systems, aligning with CETESB guidelines.
Whether conveying grain in the Campinas agricultural hubs, handling sugar processing, or carbonating beverages, zero-tolerance policies regarding process oil contamination are mandatory. Our clean systems provide pure air, protecting both consumer health and brand equity.
In critical chemical processes in the ABCDR industrial area, clean, reliable air is required for raw material transport, tank fluidization, and process cooling. Explosion-proof designs and smart control integrations ensure high safety standards under demanding conditions.
High-pressure nitrogen and air systems are vital for laser cutting. The presence of oil in the assist gas can contaminate the focusing lens or damage the workpiece. Our oil-free air solutions keep operations clean, maximizing cutting quality and optics life.
