Refrigerated dryers – BLD series
BLD series
Compressed air contains oil, solid particles and water vapors. Together, they form an abrasive, often acidic, oily sludge. Without air treatment, this murky mix will enter the compressed air system, corroding pipe work, damaging pneumatic tools and potentially compromising final products. To avoid condensation, compressed air must be dried. The BLD refrigerated dryer is a reliable, cost effective and easy to use solution. The BLD series offers a pressure dew point as low as +3 °C for a wide range of applications and industries. The dryer can be used at different pressures and consumes hardly any processed compressed air.
