CFW11 — WEG CFW11 High-Performance Variable Speed Drive
The WEG CFW11 High-Performance Variable Speed Drive is WEG's premier high-power frequency inverter, available from 1.1 kW to 2,800 kW at 380–690 V three-phase, making it the platform of choice for heavy-duty industrial applications in oil and gas, mining, desalination, cement, and petrochemical processing across Saudi Arabia and the wider GCC. The CFW11's field-oriented vector control with or without encoder feedback delivers dynamic torque response and speed regulation accuracy that rivals European premium drives, while its modular architecture — separate power and control sections — allows maintenance without a full drive shutdown, a critical feature for continuous-process industries that cannot afford unplanned downtime.
Technically, the CFW11 supports scalar (V/F), sensorless vector (VVW), and closed-loop vector control modes across its full power range. Its built-in STO (Safe Torque Off) function meets SIL 2 / PLd requirements (IEC 62061, ISO 13849-1), and the extensive protection suite — covering ground fault, input/output phase loss, overtemperature, overspeed, overcurrent, and DC bus overvoltage — is designed for unmanned remote pump stations and compressor buildings. The drive accepts 380–480 V and 500–690 V supplies, enabling use on both the standard Saudi 380 V grid and the higher-voltage industrial supplies found in ARAMCO and SABIC facilities. IP20 to IP55 enclosures and 50°C ambient operation are standard.
The CFW11 has an established track record on demanding Saudi projects: ARAMCO Berri and Abqaiq gas plant compressor drives, MARAFIQ Jubail desalination high-pressure pump trains, and SWCC major pump station refurbishment projects have all deployed CFW11 units. SABIC contractors in Jubail routinely specify the CFW11 for reactor cooling pump drives and large blower applications where process reliability is paramount. The drive's energy recovery capability (available with braking unit or AFE front end) delivers measurable energy savings on hoist and crane applications, and its compatibility with PROFIBUS, PROFINET, EtherNet/IP, and Modbus TCP ensures integration into both legacy and new DCS platforms across the Kingdom's process plants.
Razz Middle East provides the CFW11 with full project support from pre-sales engineering through commissioning and ongoing maintenance contracts. We maintain stock of mid-range frame sizes and can arrange factory-order delivery on large-frame units with defined lead times agreed at order stage. Pricing is in SAR with transparent delivery schedules. Our engineering team holds WEG product training certification and provides on-site drive commissioning, startup testing, and operator training across Saudi Arabia.

Key Features & Benefits
- Field-oriented vector control with and without encoder feedback delivers torque accuracy and speed regulation performance equivalent to premium European drives at competitive pricing.
- Modular architecture with separate power and control sections allows control board replacement without removing the drive from the cabinet, minimising maintenance downtime in continuous-process plants.
- Built-in STO (Safe Torque Off) certified to SIL 2 / PLd eliminates need for external safety relays in most machine guarding and emergency stop applications.
- Accepts 380–480 V and 500–690 V supply voltages, covering both standard Saudi grid and higher-voltage industrial supplies at ARAMCO and SABIC facilities without separate transformer.
- Extensive fault logging and process data recording with time stamps for post-event analysis, reducing troubleshooting time in remote pump stations and compressor buildings.
- Compatible with PROFIBUS, PROFINET, EtherNet/IP, and Modbus TCP enabling integration into both legacy and modern DCS platforms across the Kingdom's process industries.
Industrial Applications in Saudi Arabia
- Gas compressor drives at ARAMCO upstream facilities in the Eastern Province, where sensorless vector control maintains precise speed under varying suction pressure conditions.
- High-pressure pump drives at MARAFIQ and SWCC desalination plants in Jubail and Yanbu, where continuous 24/7 operation demands maximum drive reliability.
- Large blower and reactor cooling pump drives at SABIC petrochemical plants in Jubail Industrial City, where process reliability is a safety-critical requirement.
- Cement mill drives at Saudi Cement and YACCO plants across the Kingdom, where the CFW11's high-overload capacity handles the demanding torque profile of ball mill starting.
- Hoist and crane drives in heavy lifting applications at ports and industrial facilities, where regenerative braking recovers energy back to the supply during lowering.
- Large fan drives in power station cooling systems and industrial ventilation, where precise speed control maintains exact airflow rates under varying system resistance.
