Nidec & Emerson Control Techniques VFD Distributor in Saudi Arabia

A VFD (Variable Frequency Drive) — also called an inverter, drive, or motor drive — is an electronic device that controls the speed and torque of an AC motor by varying the frequency and voltage supplied to it. VFDs are widely used in industrial automation, HVAC systems, pumps, fans, and compressors to achieve energy savings and precise motor control.

The terms VFD, inverter, drive, and motor drive are often used interchangeably. A VFD varies motor speed by changing frequency. An inverter converts DC power to AC — which is a core function inside every VFD. Motor drive is a broader term covering any device that controls motor speed and torque, including AC drives, DC drives, and servo drives.

DASH Control Systems is the authorized distributor and repair center for Nidec Control Techniques (formerly Emerson Control Techniques) in Saudi Arabia. We supply the full range of Nidec drives including Commander C, Commander S100, F600 Pump Drives, and high-power modular inverters up to 3500 HP, with local stock in Riyadh, Jeddah, and Al Khobar.

DASH Control Systems stocks a wide range of Nidec Control Techniques VFDs in Saudi Arabia including: Commander C (up to 132 kW), Commander S100 (up to 11 kW), F600 Pump Drives (up to 2.8 MW), 500 kW Power Modules, and legacy models such as Unidrive SP, Unidrive M700, M701, M702, M400, M600, Digitax HD, and Mentor MP — all with a 5-year warranty and full local support.

Control Techniques is a UK-based manufacturer of premium AC and DC drives, originally part of Emerson Electric. In 2017, Emerson’s drive division was acquired by Nidec Corporation and rebranded as Nidec Control Techniques. The drives are the same world-class product — only the brand ownership changed. DASH Control Systems supports all generations across Saudi Arabia.

VFDs save energy by running motors at the exact speed required instead of full speed. In pump and fan applications, reducing motor speed by just 20% can cut energy consumption by nearly 50%. Installing a VFD on AHU fans, chiller pumps, and cooling tower motors typically delivers 30–50% energy savings — critical for Saudi Arabia’s climate-intensive facilities.

Yes. DASH Control Systems is an authorized Nidec Control Techniques Repair Center in Saudi Arabia. Our team of 7 application engineers repairs and supports legacy and current drives including Unidrive SP, Mentor II, Mentor MP, Unidrive M series, Digitax HD, and modular inverters up to 2800 kW. We also handle drive migration from obsolete models to current Nidec VFDs.

VFDs and motor drives are used across all sectors in Saudi Arabia including: HVAC systems in towers, hospitals, hotels, and government buildings; water pumping and desalination plants; oil & gas and petrochemical facilities; and manufacturing industries. DASH Control Systems has supplied Nidec drives to SABIC, NWC, MODON, Saudi Aramco contractors, and RSAF.

Power factor measures how efficiently electrical power is converted into useful work. A power factor of 1.0 means 100% efficiency with no reactive losses. Modern Nidec Control Techniques VFDs include built-in DC chokes and optional harmonic filters to minimize impact on the supply network. DASH Control Systems also offers capacitor bank and SVG solutions for facilities with low power factor.

Harmonics are a common side effect of non-linear loads such as VFDs, UPS systems, and rectifiers. Solutions include detuned reactors to protect capacitor banks, passive harmonic filters to reduce specific harmonic orders, and active harmonic filters (AHF) for full harmonic cancellation. Nidec Control Techniques drives also offer built-in EMC filters and optional input reactors to minimize harmonic injection at the source.
