Inverter & Control Panel Solutions for Fan Cooling and Heating Systems
We design and supply high-performance inverter and control panel solutions for fan-driven cooling and heating applications. Our systems improve efficiency, enhance comfort, reduce energy usage, and deliver reliable airflow control across a wide range of industrial, commercial, and HVAC environments. Whether you need a modern retrofit or a complete new installation, we can provide the right solution for your system.
Energy Savings Through Variable Frequency Drives (VFDs)
Fans in cooling and heating systems often run at full speed even when demand is low. A Variable Frequency Drive (VFD) allows the fan speed to match real-time temperature and airflow requirements, dramatically reducing power consumption.
Benefits of using VFDs include:
- Significant energy cost reductions
- Reduced wear and extended fan/motor lifespan
- Smoother, quieter operation
- Improved temperature control and air distribution
- Lower maintenance requirements
For both supply and extract fans, VFD control is one of the most effective ways to optimise system performance.
New Installations & Retrofit Solutions
Our systems are designed for flexibility, offering seamless integration for:
New installations – fully engineered panels built to suit any heating or cooling fan configuration.
Retrofits – upgrade existing starter panels with modern VFDs to improve efficiency without replacing the entire fan unit.
We work with all major fan types, including axial, centrifugal, mixed flow, EC conversions, and multi-fan systems.
Built-In PLC Functionality With Invertek Optidrive ECO
Using the Invertek Optidrive ECO’s onboard PLC-style functionality, we can integrate a wide range of intelligent control features directly within the drive itself. This eliminates the need for additional PLCs, relay logic, or separate control modules—reducing system cost, wiring complexity, and installation time, while improving reliability.
This built-in intelligence allows for:
- Demand-based fan speed control
- Automated run and stop profiles
- Temperature monitoring and automatic temperature-based control
- Filter or airflow condition monitoring
- Custom timed sequences
- Safety interlocks
- Multi-fan coordination
In many cases, the Optidrive ECO alone can perform all required system logic—offering a compact and cost-effective solution without external controllers.
Full BMS & Industrial Network Connectivity
Our control panels easily integrate into modern Building Management Systems and industrial networks, ensuring full visibility and intelligent control.
Supported communication protocols include:
- BACnet (IP & MSTP)
- Modbus (RTU & TCP)
- Ethernet/IP
- Profinet
- Hardwired analogue and digital I/O
This ensures your fans operate efficiently while remaining fully synchronised with the wider site control architecture.
Flexible Control Options
Basic Control Panels
Ideal for simple applications:
- Push-button control
- Indicator lamps
- Speed potentiometers
- Traditional relay logic
Advanced PLC & HMI Control
For multi-zone, sequenced, or complex systems:
- Touchscreen HMI interfaces
- Real-time status, alarms, and diagnostics
- Automated control sequences
- Remote monitoring and adjustment
(And thanks to Optidrive ECO’s onboard PLC functionality, many systems may not require a standalone PLC at all.)
Soft Start & DOL Options
For fixed-speed applications or where budget is the priority, we also offer:
- Soft Start – controlled motor acceleration with reduced stress
- Direct-On-Line (DOL) – simple and reliable motor starting
Smarter, More Efficient Fan Control
Whether you're upgrading an existing installation or commissioning a new system, our inverter and control panel solutions deliver efficient, reliable, and intelligent airflow management for all cooling and heating applications.
