Rotary Screw Compressors
Fixed speed rotary screw compressors are an ideal piece of equipment for those with a fairly consistent use for compressed air. Oil-injected rotary screw compressors incorporate the very latest technological advances and manufacturing processes to provide you with a continuous supply of economic and reliable high quality air. However, when air demand reduces, the compressor will run offload making it less efficient than a variable speed compressor.
Variable speed rotary screw compressors are the right choice for a fluctuating demand in compressed air. Featuring inverter technology, the compressor is able to smoothly adjust the motor speed and power consumption to respond to any changes in product demand, adjusting product production and ensuring no offload running. The result is a more efficient creation of compressed air, with many situations reducing energy costs by up to 35% or more. A return on investment can often be seen within as little as 12 – 18 months.
