Variable speed rotary screw compressor

EKO 200-315 VST

Built for demanding industries, EKO 200-315 VST oil-injected screw compressors combine high-volume airflow with efficient variable-speed operation, liquid-cooled PM motor technology and intelligent control for reliable, continuous compressed-air production.

EKO 250 PM

Liquid-cooled PM

The permanent magnet motor uses a dedicated glycol circuit for efficient thermal management under heavy loads and continuous operation.

Variable Output

Variable-speed operation maintains efficiency at different speeds and load conditions while supporting stable compressor control.

Smart Monitoring

ES4000T and ICONS provide operating data, service visibility, energy analysis and remote access across connected devices.

Advanced liquid-cooled PM technology for demanding industry

The EKO 200-315 VST range is engineered for demanding industries that require continuous, high-volume compressed air. Its permanent magnet motor uses a dedicated liquid glycol cooling system to maintain stable internal temperatures during heavy loads and continuous operation, independently of ambient conditions.

Efficient heat dissipation enables greater power density and a compact motor design, while the closed cooling circuit reduces exposure to contamination. Consistent efficiency at different speeds and varying loads supports stable compressor control, dependable performance and optimized operating costs.

EKO 250 PM

The range combines variable-speed operation with a permanent magnet motor and a dedicated liquid glycol cooling system. Liquid cooling supports stable motor temperatures and consistent performance across changing load conditions. The closed circuit also makes the configuration suitable for dusty, poorly ventilated or enclosed industrial environments.

The closed glycol circuit protects the motor-cooling system from external contamination and maintains thermal performance independently of surrounding air conditions. This makes the technology suitable for dusty environments, enclosed spaces and installations with limited ventilation.

The ES4000T touchscreen displays service status, scheduled maintenance, warnings and shutdown alarms. Available service-related options include 8,000-hour oil and food-grade oil.

Liquid cooling provides efficient heat removal, allowing a compact PM motor to deliver high power density without compromising thermal stability. Maintaining motor efficiency at low speeds and under changing loads supports optimized compressor operation and helps keep operating costs under control.

ICONS connectivity supplies machine data and insights through computers, tablets and smartphones. This supports early identification of potential issues, analysis of energy consumption and CO₂ emissions, and energy reporting for ISO 50001 site compliance. Energy recovery and witness test reports are available as options.
