Product Types in Stock

Gulf Union Ozone carries six drive and motor control product families to IEC 61800 and IEC 60947-4-2 standards — with full certification documentation and fieldbus configuration support for Saudi Arabia industrial projects.

Type 01

General Purpose VFDs — Low Voltage (0.37kW–315kW)

Scalar (V/f) and vector control VFDs for general-purpose pump, fan, conveyor, and compressor speed control in Saudi Arabia industrial facilities. Three-phase 380–480V input, 50/60Hz, IGBT power stage with carrier frequency 2–16kHz, overload capacity 110% for 60 seconds (normal duty) or 150% for 60 seconds (heavy duty). Built-in EMC filter Class C2 (IEC 61800-3 Second Environment), built-in DC choke on 11kW and above, built-in brake transistor on units to 22kW. MODBUS RTU RS-485 as standard. Keypad with LCD display, multi-language menu. IP20 chassis for panel mounting; IP55 wall-mount version available. Integrated PID controller for pressure and flow regulation on pump and HVAC applications. Operating temperature 0°C to 50°C ambient.

Type 02

Heavy Duty & Process VFDs (11kW–630kW)

High-overload (150% / 60s, 180% / 3s) VFDs for demanding industrial loads — crusher drives, conveyor starting, centrifuge drives, and reciprocating compressors with high inertia in Saudi Arabia process plants. Sensorless flux vector (SFV) and closed-loop field-oriented control (FOC) with encoder feedback options for precise speed and torque regulation. IP54 or IP55 enclosure rated to 50°C ambient (60°C with derating). Safe Torque Off (STO) function to SIL2 / PL-d (IEC 62061 / ISO 13849-1) as standard — enabling integration with safety relay circuits without additional hardware. PROFIBUS DP, PROFINET, EtherNet/IP, and DeviceNet fieldbus option cards. Modular design with plug-in option cards for I/O expansion, encoder, and brake chopper. Suitable for pump VFD retrofits on existing NEMA or IEC motor installations.

Type 03

Electronic Soft Starters (7A–1200A)

Thyristor (SCR) soft starters to IEC 60947-4-2 for controlled motor start-up and soft stop — reducing mechanical shock on pump impellers, gearboxes, and conveyor belts, and eliminating water hammer in Saudi Arabia piping systems. Voltage ramp and current limit starting modes; adjustable ramp time 1–30 seconds. Built-in bypass contactor on units 75A and above (eliminates SCR heating during run). Built-in motor protection: overload, phase loss, phase imbalance, thermistor input. IP20 chassis or IP55 wall-mount enclosure. Current range 7A (1.5kW) to 1200A (630kW). Three-phase 380–480V, 50/60Hz. MODBUS RTU RS-485 standard on all current ratings 30A and above. Suitable for centrifugal pumps, belt conveyors, compressors, and fan drives. Full overload protection curves and application guidelines available on request.

Type 04

Motor Control Centres (MCCs)

Intelligent motor control centres (MCCs) with combination starter sections — direct-on-line (DOL), star-delta (Y/Δ), and VFD or soft-starter combinations — in fully type-tested assemblies to IEC 61439-2 (Form 3b or 4 internal separation). MCC construction: floor-standing double-front or single-front, 200mm or 400mm section width, busbar rating 630A–3200A, IP31 standard with IP54 option. Intelligent motor controllers (IMCs) with MODBUS or PROFIBUS integration for remote monitoring of motor current, power, and fault status from DCS in Saudi Arabia plant control rooms. Outgoing ways fitted with motor protection circuit breakers (MPCBs) and contactors from major brands. Withdrawable plug-in motor starter units for live maintenance. Factory-built, type-tested, delivered ready to wire.

Type 05

Regenerative Drives & Active Front-End (AFE) Units

Regenerative (four-quadrant) VFDs with active front-end (AFE) rectifier for returning braking energy to the supply network — eliminating braking resistors and reducing energy consumption on crane hoist drives, centrifuge decelerations, downhill conveyor systems, and test bench drives in Saudi Arabia. AFE units maintain near-unity power factor (PF 0.99) and significantly reduce harmonic current distortion (THDi typically below 5%) compared with standard diode-bridge VFDs — critical for facilities with strict power quality requirements from SEC. Voltage: 380–480V / 3ph / 50Hz. Power range 11kW–800kW. 12-pulse or 18-pulse input transformer option for legacy installations with harmonic concerns. MODBUS RTU standard; PROFIBUS and EtherNet/IP optional. IP20 or IP54 enclosure.

Type 06

VFD Accessories — Filters, Reactors & Bypass Contactors

EMC line filters (IEC 61800-3 Class C1 / C2) for VFDs installed close to sensitive instrumentation and communication equipment in Saudi Arabia process plants. Line reactors (AC input choke) 3–5% impedance for harmonic reduction, protection against supply transients, and extended VFD IGBT life — essential where supply impedance is low (near transformer secondary). dV/dt output filters and sine-wave filters for long cable runs from VFD to motor (above 50m) — prevent insulation stress in inverter-duty motors. Motorised bypass contactors with manual changeover for critical pump and fan drives requiring uninterrupted operation during VFD maintenance. Braking resistors (dynamic braking) IP20 and IP55 for high-inertia loads. All accessories matched and rated for VFD power range 0.37kW–630kW.

FAQ

Frequently Asked Questions — VFDs & Motor Drives Saudi Arabia

What VFD enclosure protection ratings do you supply for Saudi Arabia outdoor and hazardous locations?

Gulf Union Ozone supplies variable frequency drives in IP20 (indoor panel mounting), IP54 (dusty indoor or sheltered outdoor), and IP55 (outdoor duty) protection ratings to IEC 60529 — essential for Saudi Arabia's dusty desert environments and coastal humidity. For installation in hazardous Zone 2 areas, we supply ATEX-rated IP65 VFD enclosures with purge-and-pressurisation (Ex-p) systems to IEC 60079-13. Wall-mount, floor-standing, and panel-built VFD assemblies are available. All units are rated to 50°C ambient as standard, with derating curves for higher temperatures available in the datasheet. Contact us on WhatsApp 966550988062 for enclosure selection guidance.

Do you supply VFDs with MODBUS, PROFIBUS, and EtherNet/IP fieldbus for DCS and SCADA integration in Saudi Arabia plants?

Yes. Gulf Union Ozone stocks VFDs with built-in MODBUS RTU (RS-485) as standard on most units — the most common fieldbus protocol used in Saudi Arabia oil and gas, water treatment, and desalination plant DCS and SCADA systems. PROFIBUS DP, DeviceNet, EtherNet/IP, and PROFINET communication cards are available as plug-in option modules for all major VFD brands we supply. Fieldbus-enabled drives support remote start/stop, speed reference, fault monitoring, and energy data logging without additional signal converters. We can provide pre-configured drives with your specific register map on request. Full wiring diagrams and fieldbus configuration documentation included.

Can soft starters reduce pump surge and water hammer in Saudi Arabia water infrastructure projects?

Yes. Soft starters are the primary solution for controlling pump start-up ramp rates in water supply, sewage pumping, and desalination projects across Saudi Arabia to eliminate water hammer and reduce mechanical stress on pipework and pump impellers. Gulf Union Ozone stocks electronic soft starters in 7A–1200A current ratings (IEC 60947-4-2) with adjustable current ramp, voltage ramp, and pump-deceleration (soft stop) control. Built-in bypass contactor for full-voltage run reduces thermal load on power semiconductors. Thyristor (SCR) technology, IP20 chassis or IP55 standalone enclosure. Suitable for centrifugal pumps up to 630kW. Documentation includes CE declaration of conformity and SASO import compliance data.
