The 7–22 kW range of screw compressors, built on reliability and flexibility, is designed for continuous operation in industry, manufacturing, and workshops. The integrated screw block allows operation at lower speeds, reducing energy consumption and increasing service life. A wide choice of versions—from base (without receiver) and receiver-mounted to Airstation packages with a refrigerated dryer, as well as variable-speed and heat recovery options—lets you tailor the system precisely to the specific application and space. L11 (11 kW) provides up to 1.59 m³/min of air delivery while maintaining low noise levels and compact dimensions. The model meets German engineering quality standards and supports Iconn remote monitoring and the SMARTair master compressor control system.

Functions:

• Unified screw block with integrated oil separator, oil filter, and thermostatic valve – fewer hoses and components, higher reliability
• Combined air/oil cooler with bypass – rapid warm-up, stable oil temperature, less condensate, and low discharge air temperature
• High-efficiency IE3 electric motor – lower energy consumption and CO2
• Automatic drive belt tensioning system – precise tension and longer belt life
• Factory-filled lubricant – oil change interval up to 4,000 hours
• Low noise level – the unit can be installed close to the point of use
• Reliable operation up to 45 °C ambient temperature
• Small footprint – the base compressor occupies about 0.4 m²
• In-house manufactured airend – precise rotors and consistent specific energy consumption over a wide speed range
• Delcos Pro SE controller with 2.8" graphic display: pressure and air/oil temperature readings, total and load hours, upcoming maintenance indicator, extended fault history, real-time clock, timer-controlled start/stop, remote start/stop, automatic restart after power failure, second pressure setting, status indications
• Connectivity and data: RS485 (Modbus RTU), Micro-SD data logging, integrated BLS function and Web-Server Light; Ethernet connection via optional RS485 module
• Iconn remote monitoring capability – real-time parameter tracking, alerts, and data analytics
• SMARTair master compressor control system – multi-compressor sequencing, pressure stability, and energy savings
• German engineering quality standard – reliability and durability
