Benefits
High energy efficiency and lower operating costs
The optimized screw block design and advanced drive systems ensure high efficiency and significantly lower specific energy consumption throughout the compressor's service life.
HPM technology on RS models
Regulated-speed (RS) versions use Hybrid Permanent Magnet (HPM) motors with exceptional efficiency, consistent performance across the entire operating range, and unlimited start/stop capability.
Maximum reliability and long service life
The patented UltraCoat™ protection on rotors prevents corrosion and wear, while the robust design and stainless steel piping on the cold side ensure long-term reliable operation even in demanding environments.
Flexible cooling and operating configurations
Air-cooled and water-cooled versions are available, together with fixed-speed or regulated-speed models, enabling optimal adaptation to actual system requirements.
Easy maintenance and accessibility
The design provides quick access to all key components without special tools. Long service intervals and a clear internal layout reduce maintenance time and costs.
iConn – intelligent real-time monitoring
The integrated iConn system enables remote monitoring, predictive maintenance, and performance optimization, reducing unplanned downtime and increasing system energy efficiency.
Ready for heat recovery
The possibility of utilizing up to 94% of waste heat for water or space heating provides additional energy savings and reduces the overall system carbon footprint.
