These applications include electronics, food and beverage processing, pharmaceutical manufacturing, chemical and petrochemical processing, fermentation, wastewater treatment, pneumatic conveying, non-woven textile manufacturing and many more.

VSD&PM: DRIVING DOWN ENERGY COSTS
Over 80% of a compressor's lifecycle cost is taken up by the energy it consumes. Moreover, the generation of compressed air can account for more than 40% of a plant's total electricity bill. To drive down your energy costs, Crownwell pioneers Variable Speed Drive (VSD) and Permanent Magnetic (PM) technologies in the compressed air industry. VSD&PM lead to major energy savings, while protecting the environment for future generations. Crownwell offers a wide range of integrated VSD&PM compressors in the market
