Precise motor control — with real energy savings.
A Variable Frequency Drive (VFD) — also called an inverter or variable speed drive — controls the speed and torque of electric motors by adjusting the frequency and voltage of the power supply. Instead of a motor running at full speed all the time, the VFD lets it run at exactly the speed the process demands.
The result: lower energy consumption, less mechanical wear, softer motor starting, and precise process control for applications like pumping, ventilation, and compression.
In Alberta, where energy costs are significant, a VFD is an investment with a measurable payback — especially on continuous process applications.
Full installation, programming, and commissioning.
Selection and sizing: motor, load, and process requirements analysis to select the right drive.
Electrical installation: power cabling, control wiring, harmonic filters, and grounding connections.
Programming: operating parameters, acceleration/deceleration ramps, current limits, and control system integration.
Commissioning: functional testing, performance verification, and parameter fine-tuning.
PLC/SCADA integration: communications configuration (Modbus, Profibus, EtherNet/IP) for remote control.
Maintenance: periodic inspection, ventilation filter cleaning, and firmware updates.
Troubleshooting: diagnosing drive faults, communication issues, and process instability.
Where variable frequency drives make a difference.
- Process pumps (centrifugal, dosing, water)
- Industrial fans and exhaust systems
- Air and process compressors
- Conveyor belts and transport systems
- Cooling towers and industrial HVAC systems
- Agitators, mixers, and process equipment
- Pressurisation systems and flow control
Correct installation that protects your investment.
A poorly installed VFD causes more problems than it solves: harmonics that damage the electrical system, undersized cable leading to intermittent faults, wrong parameters causing process instability. Our team understands not just how to install a VFD, but how to integrate it properly with the control system and the process.
Technical selection and sizing: we avoid under-engineering and over-engineering
Control system integration: VFD connected to PLC and SCADA without duplicating effort
