A regenerative blower is an economic and effective alternative to compressed air

One of the most widely used mechanisms for drying packages in the industry is compressed air, that is, electric power as pneumatic pressure. Using compressed air establishes a ratio equivalent to six to eight electric energy units for the generation of one compressed air energy unit. Today, approximately 5 billion tons of air are compressed every year throughout the planet, causing a 400-billion-kWh consumption, costing 20 billion dollars. Check on the chart on the right the waste figures:

There are more efficient and economic systems that can replace compressed air generating significant outcomes for the industry, not only in terms of savings, but also sustainability and competitiveness, key indicators to any business. Spraying Systems introduces the Windjet® Air Blower Drying System, one of the best proven solutions. It consists of a regenerative blower featuring a specially designed air knife, which provides the best usage of the generated air flow. Another design benefit is a visual guide for directing the air stream, making it easier to adjust the knife positioning, assuring maximum coverage.

Regenerative blowers are based upon a method that works the air in a way that allows it to pass over an impeller blade and slide over it, moving forward to another blade. These devices require little maintenance once they are DIRECT TO DRIVE machines, that is, directly coupled to the engine instead of driven by belts which have higher maintenance cost and compromise ball bearings that, by their turn, need to be periodically replaced, in addition to increasing noise.

-One of Spraying Systems’s regenerative blower success cases is a Brazilian subsidiary of a multinational beverage company. When it still used compressed air with 12mm pneumatic hoses, 6 bar work pressure, 24-hour-a-day production, 320 operation days per year, with a kW/h cost of R$ 0.28, the yearly electric power cost was R$ 125 thousand, considering just this line. By replacing the hoses with a 20HP blower assembly, the yearly electric power cost dropped to R$ 37.5 thousand. The 70% reduction in consumption enabled PAYBACK within nine months’ time.

It is worth reminding that the beverage industry requires an accurate drying of packages at those spots where it is necessary to mark lot data, manufacturing and expiration dates for tracking units manufactured on each production site by the Brazilian Federal Revenue Service. It is essential that the area where the Sicobe (‘Sistema de Controle de Produção de Bebidas’ – Beverage Production Control System) information will be printed is properly dry. Therefore, the regenerative blower avoids the common rework on those lines using compressed air and allows the company to increase its productivity.

If your company uses compressed air, Spraying Systems team is available to conduct an assessment visit and provide a report estimating the gains you may have by replacing compressed air with a regenerative blower.
