In modern industrial engineering across Spain's northeastern industrial belt, Medium Voltage Drives (MVDs) serve as the crucial nerve center for large-scale electro-mechanical energy conversion. Operating typically within range bands of 2.3 kV, 3.3 kV, 4.16 kV, 6.6 kV, 10 kV, and up to 13.8 kV, these sophisticated Variable Frequency Drives (VFDs) regulate large synchronous and induction motors powering high-inertia loads without incurring astronomical line-loss penalties associated with low-voltage high-current infrastructure.
For industrial plant operators in Barcelona, Zona Franca, Martorell, and Granollers, selecting the appropriate MV drive architecture is directly linked to operating expenses (OPEX), grid power quality compliance, and total cost of ownership (TCO). Our factory engineering teams specialize in three primary MV drive inverter topologies tailored to diverse process demands:
A critical engineering consideration for factories operating within the Spanish national grid (Red Eléctrica de España / Endesa distribution network) is strict compliance with IEEE 519-2022 and IEC 61800-3 harmonic current limits. Unmitigated harmonics generated by non-linear industrial loads cause transformer overheating, capacitor bank degradation, and sensitive instrumentation failures. Our Medium Voltage Drives incorporate 18-pulse, 24-pulse, or 36-pulse phase-shifting isolation transformers, as well as Active Front End (AFE) regenerative rectifiers, maintaining Total Harmonic Distortion (THD) under 3% directly at the Point of Common Coupling (PCC).
From maritime port decarbonization to high-volume chemical refining and municipal water purification, custom MV drive installations power Catalonia's most vital infrastructure.
Implementation of 6.6kV Active Front End MV Drives for Shore-to-Ship power supply (Cold Ironing), container gantry crane hoists, and heavy harbor tug electrification. Enables zero-emission berth operations compliant with European maritime sustainability mandates.
High-voltage explosion-proof (ATEX-certified) MV drive enclosures governing large centrifugal gas compressors, continuous chemical mixers, and high-pressure crude transfer pumps requiring non-stop 8,760 hours/year operational reliability.
Variable speed Medium Voltage Drives managing high-pressure Reverse Osmosis (RO) booster pumps (up to 10MW capacity). Soft-starting capability eliminates hydraulic water hammer spikes and reduces desalination electrical energy consumption by up to 35%.
Dynamic MV drive controllers integrated into high-tonnage mechanical servo press lines at major automotive plants. Precise vector torque control allows rapid acceleration and deceleration cycles with energy recovery routed back to plant microgrids.
Large-capacity MV VFD units controlling 3.3kV and 6.6kV centrifugal chiller compressors for urban district cooling loops across Barcelona's 22@ technology district, optimizing part-load efficiency during intense Mediterranean summer peaks.
Heavy-duty MV drives powering kiln drives, high-pressure grinding rolls (HPGR), draft fans, and multi-motor synchronized paper machine drives operating under demanding thermal and dust-laden atmospheric conditions.

As Spain accelerates its national energy transition plan (PNIEC) and Catalonia enforces the Llei del Canvi Climàtic, industrial manufacturers operating in Barcelona face increasing regulatory pressure to eliminate energy waste. Electric motors and their driving electronics consume over 68% of total electrical energy in heavy industrial facilities. Consequently, retrofitting aging fixed-speed legacy motors with high-efficiency Medium Voltage Drives represents the single most impactful decarbonization initiative available to plant managers.
Under European Union Ecodesign Regulation (EU 2019/1781), energy efficiency requirements for electric drives and motors have expanded to mandate minimum IE3 and IE4 standards. Modern MV Drives engineered by our factory go beyond basic speed adjustment by incorporating intelligence-led features:
Comparing traditional damper throttling versus variable speed Medium Voltage Drive control over 8,000 annual operational hours in Barcelona.
Backing every Medium Voltage Drive and industrial motor installation with over 120 years of continuous electrical machine manufacturing excellence, rigorous testing, and local support.
With an pedigree dating back over a century, our manufacturing facilities have consistently set the benchmark for heavy industrial rotating machinery, AC/DC electric motors, and customized electronic drive solutions. Unlike standard equipment distributors, we operate as a full-spectrum OEM designer and manufacturer.
Our specialized engineering team designs matched motor-and-drive combinations where insulation systems, harmonic voltage tolerances, bearing stray current protection (insulated bearings & shaft grounding rings), and thermal cooling profiles are perfectly harmonized under one roof.
We understand that industrial downtime in high-throughput facilities across Barcelona, Tarragona, and Girona translates directly into heavy financial loss. That is why we maintain a dedicated technical support hub providing guaranteed under 24-hour response times on all working days across northeastern Spain.
Services include full factory acceptance testing (FAT), site commissioning, vibration analysis, diagnostic laser alignment, drive retrofitting, harmonic compliance audits, and genuine serial-tracked OEM spare parts supply.
We manufacture and supply Medium Voltage Drives for all standard regional operating voltages, including 2.3 kV, 3.3 kV, 4.16 kV, 6.6 kV, 10 kV, and 13.8 kV. Units are custom-configured for 50 Hz European distribution grids and can be supplied with step-down or step-up multi-winding phase-shifting isolation transformers.
Our MV drives utilize multi-pulse phase-shifting topologies (18-pulse, 24-pulse, or 36-pulse) or Active Front End (AFE) PWM rectifiers. This keeps Total Harmonic Current Distortion (THDi) and Voltage Distortion (THDv) well under 3% at the point of common coupling, easily satisfying IEEE 519-2022 and local Spanish electrical grid standards without external passive filter banks.
Standard modular drive components are maintained in regional stocking warehouses for quick assembly. Fully customized medium voltage drive cabinets (including specialized IP54/IP55 air-cooled or water-cooled enclosures and ATEX certifications) are typically manufactured, tested, and dispatched within 8 to 14 weeks, backed by localized factory FAT testing.
Yes. We specialize in drive retrofitting. Our Cascaded H-Bridge (CHB) multi-level output waveform is gentle on motor winding insulation, eliminating the severe dV/dt voltage stress associated with older drives. This allows retrofitting on existing high-voltage motors without requiring expensive motor insulation upgrades or output sine-wave filters.
Absolutely. For coastal and marine installations in Barcelona and coastal Catalonia, we offer C4-H and C5-M high-durability anti-corrosion polyurethane paint systems, stainless steel fasteners, marine-grade copper busbars with nickel plating, and IP54 to IP65 sealed liquid-cooled cabinets with integrated heat exchangers.
