High Efficiency

Advanced iPM technology delivers up to 45% energy savings and higher efficiency than traditional VSD units, ensuring lower running costs.

Robust Design

Engineered for harsh conditions up to 46°C, the IP54 drivetrain and durable components ensure continuous, dependable operation.

Quiet & Compact

Low-noise performance down to 63 dB(A) allows installation at the point of use, reducing piping needs and saving installation costs.

Advanced performance and energy savings for demanding industries

The RMP 8–22 IVR range uses next‑generation interior permanent magnet technology to deliver superior efficiency at every load. By adjusting motor speed to match air demand, it significantly cuts energy waste while ensuring stable pressure and continuous performance. Its rugged, low‑noise design integrates seamlessly into compressor rooms or can be placed directly at the point of use thanks to sound levels as low as 63 dB(A).

Each model combines a direct‑drive VSD system, IP54 protection, and an advanced ES4000T touchscreen controller for optimal monitoring and control. With options for floor or tank mounting and integrated dryers, the range offers unmatched flexibility. High‑quality engineering, oversized coolers, and improved motor‑airend coupling guarantee long‑term reliability with minimal maintenance demands.

The RMP 8–22 IVR series operates between 4 and 10 bar with power ratings from 7.5 to 22 kW, covering a wide range of industrial air demands. Free Air Delivery varies across the range, offering efficient output tailored to different applications. Sound levels start from 63 dB(A), enabling flexible installation even in production areas.

All models include an oil‑cooled IE4 iPM motor for improved thermal stability and durability. The compressors integrate an ES4000T controller for detailed performance insights and energy optimization. Designs include base‑mounted or tank‑mounted options with or without dryers to match diverse operational requirements.

Maintenance is streamlined thanks to the simplified drive‑train connection and optimized component accessibility. The oil‑cooled iPM motor is maintenance‑free, supporting long service intervals while maintaining top efficiency. Oversized coolers and high‑quality filtration further reduce strain on internal components.

With the ES4000T controller and ICONS connectivity, operators receive real‑time data, alerts, and service insights that enhance uptime and prevent unexpected failures. This proactive approach ensures the compressor continues operating at peak performance throughout its lifecycle.

The RMP 8–22 IVR delivers up to 45% energy savings compared to fixed‑speed systems, offering rapid return on investment, often within just one year. By intelligently adapting motor speed to match demand, it minimizes wasted energy and reduces pressure fluctuations, stabilizing the entire air system.

Its compact, low‑noise design allows installation close to consumption points, reducing piping losses and lowering overall installation and operating costs. Combined with robust durability and advanced monitoring, the range provides long‑term economic and environmental advantages for any facility.
