Product Parameters
Compressed air is a fundamental source of energy for the large majority of industrial processes.
However, air from a compressor is often too humid, contaminated or hot to be used in the
production chain without prior treatment.
The application of high-quality air ensures continuity and reliability of industrial applications, the highest quality standards for finished products and the optimization of production costs.
PSI Filtration offers full line of refrigeration air drying solutions, and we guarantee:
• Zero pollution risks, due to its refrigeration system, which has been researched, developed and accurately tested to avoid any refrigerant loss.
• Top energy efficiency, reducing electrical energy consumption to a minimum.
• Low Maintenance, due to technological advances in research, development, production and testing.
