L30 - L132, RS

L30-50_DelcosXL_offenThe direct driven rotary screw compressors offer significant energy savings as well as many other benefits, such as operational safety, small footprint, low noise level and high flexibility. The range comprises of 20 different models including regulated speed models and the availability of integrated dryer and heat recovery option. The two models L50 and L80 offer additional energy savings by utilising a premium size airend with optimized rotor tip speed.

  • High reliability and high quality compressed air
  • Comprehensive and user-friendly touch-screen compressor controllerOptimized-L 75 RS_offen
  • Superior energy efficiency
  • High flexibility
  • Small footprint
  • Excellent accessibility contributing to the low maintenance costs

The high output in-house made airend with slow rotational speed combined with the energy saving IE 3 electric motor delivers optimum energy efficiency.

The RS (regulated speed) efficiently handles the varying air demand found in most plant air systems.
The compressors incorporate quality components, such as high performance separator filter, large surface after cooler and thermostatically controlled motor driven fan.

The design concept is not only based on energy efficiency but also on high availability and low maintenance costs. L55-75-F-SR-01-Airend-trimmed

Therefore these packages ensure all service points are easily accessible. The reduced number of moving parts contributes to lower maintenance costs additionally.

Delcos XL innovative touch-screen compressor controller

DELCOS3100_Steuerung_GBThe multilingual control system ensures safe and reliable operation and protects operators’ investment by continuously monitoring the operational parameters which is essential for reducing costs of ownership.
