High-Efficiency High-Voltage Motors, Slip Ring Wound Rotors & Custom Ex-Proof Machinery for Import to Turkey
As Turkey’s industrial infrastructure accelerates across manufacturing hubs in Marmara, Izmir, Kocaeli, Karabük, and Adana, the operational demand for heavy-duty electric motors capable of continuous, high-efficiency performance in aggressive thermal and dust-laden environments has reached unprecedented levels. CACW (Totally Enclosed Air-to-Water Cooled) electric motors—designated under IEC 60034-6 standard codes IC81W and IC8A1W1—represent the pinnacle of closed-circuit cooling technology for high-voltage (HV) and high-power low-voltage (LV) rotating machinery.
Unlike standard TEFC (Totally Enclosed Fan Cooled - IC411) or CACA (Totally Enclosed Air-to-Air Cooled - IC611) configurations, CACW electric motors utilize a dedicated internal air circuit coupled with a top-mounted, heavy-duty air-to-water heat exchanger. This architectural design decouples the motor’s internal thermal dissipation performance from ambient air temperature fluctuations, making CACW drive solutions indispensable for plant directors and procurement engineers across Turkey facing hot Mediterranean summers, enclosed pump stations, and severe airborne contaminants such as coal dust, cement clinker, and marine salinity.
Information Gain Key Insight for Turkish Importers: CACW (IC81W) cooling delivers up to 35% higher power density per frame size compared to CACA (IC611) motors, while reducing acoustic noise emissions to under 80 dBA at 1 meter—critical for compliance with Turkish Ministry of Environment municipal and industrial noise directives.
The operational core of a CACW electric motor consists of two isolated, highly optimized cooling circuits:
Featuring removable tube bundles (CuNi10Fe, Admiralty Brass, or 316L Stainless Steel) designed for raw industrial water quality typical in Turkish industrial zones.
Fully certified Ex ec (non-sparking) and Ex p (purged/pressurized) models compliant with Turkish TSE and European Union Directives for Zone 1 and Zone 2 gas/dust hazard zones.
Reverse-engineered mechanical footprint matching legacy Russian, European, or American frame sizes, allowing direct replacement without civil foundation alterations.
Exporting high-power CACW motors to Turkey requires deep alignment with regional industrial demands and localized environmental conditions. Our customized CACW and wound rotor motor series are engineered specifically for Turkey's core economic sectors:
Turkey stands as one of Europe’s premier steel producers. Steel rolling mills, wire rod mills, and blast furnace blowers demand motor drives that deliver exceptional starting torque while enduring high ambient radiated heat and airborne mill scale. Our YR and YZR series wound rotor (slip ring) CACW motors (380V to 11kV, up to 3200kW+) enable smooth, controlled acceleration under full load using external liquid resistance starters (LRS). The IC81W water-cooling canopy extracts intense thermal loads rapidly, preventing thermal tripping during heavy reversing duty cycles.
In explosive environments processing hydrocarbons, cooling air containing volatile gases poses immense risks. Our Ex p and Ex ec CACW electric motors maintain internal positive pressure with clean instrument air while utilizing closed-loop water cooling. This eliminates foreign explosive gas ingress while providing massive multi-megawatt drive power for continuous boiler feed pumps, gas export compressors, and crude oil transfer pumps.
Limestone crushing, raw coal grinding, and cement clinker production generate abrasive dust that clogs external cooling fins on conventional CACA (IC611) motors within days, resulting in thermal burnout. CACW electric motors completely bypass ambient air filtration problems. The heat exchanger tubes can be cleaned without opening the motor's internal winding chamber, maintaining peak thermal efficiency in the dustiest mining pits across Central Anatolia.
Low-noise municipal pumping stations operating near residential areas in Istanbul, Ankara, and Izmir benefit directly from CACW motor acoustics. By eliminating large external cooling fans, motor acoustic output drops below 78-80 dBA, fulfilling stringent Turkish environmental regulations while driving massive high-head vertical and horizontal water supply pumps.

Importers and procurement teams sourcing CACW electric motors into the Republic of Turkey must navigate specific local regulations, electrical grid standards, and environmental initiatives:
The Turkish Electricity Transmission Corporation (TEİAŞ) operates a 50Hz grid that can experience voltage fluctuations of ±10% in heavy industrial zones during peak summer demand. Our CACW motors are designed with a generous thermal margin (VPI resin insulation with Class H thermal capability running at Class B temperature limits), ensuring safe, continuous operation without coil deterioration during grid dip events.
Under the EU-Turkey Customs Union agreement, industrial rotating equipment imported into Turkey must comply with relevant CE marking directives, including the Low Voltage Directive (LVD 2014/35/EU), Electromagnetic Compatibility (EMC 2014/30/EU), and ATEX Directive (2014/34/EU) verified by accredited testing bodies (such as SGS Baseefa or TSE - Türk Standardları Enstitüsü). We provide full documentation packages including ATR movement certificates, Factory Acceptance Test (FAT) reports, and 3.1 material traceability certificates to ensure seamless Turkish customs clearance through Ambarlı, Mersin, or İzmir ports.
With rising industrial electricity tariffs in Turkey, industrial enterprises are rapidly retrofitting fixed-speed pumps and fans with VFDs. Our CACW high-voltage motors feature isolated non-drive-end (NDE) bearings to prevent damaging shaft currents, along with VPI winding treatment capable of handling high dV/dt voltage spikes associated with modern IGBT converters.

Essential Insights for Engineering Procurement Managers & Plant Directors in Turkey
CACW motors utilize water to cool the internal primary air, delivering significantly higher thermal transfer efficiency than air-to-air cooling. This results in a smaller physical frame size, higher output power density, dramatically lower operating noise (< 80 dBA), and immunity to airborne dust that rapidly fouls CACA cooling tubes.
