Invertek Drives will be at Refrigera 2025 (5-7 November) in Bologna, Italy next week, demonstrating how Optidrive variable frequency drives are helping commercial and industrial refrigeration operators improve efficiency, temperature stability and resilience as the sector continues its move towards CO₂ and other low-GWP refrigerants.
Visitors to stand E31 will be able to view a range of Optidrive models widely used in commercial refrigeration, cold storage, food production and industrial cooling environments.
The drives precisely control compressor, condenser fan and pump motors so that cooling output matches real demand rather than running at full power continuously. This approach is increasingly important as manufacturers and system operators work to reduce energy use, protect product quality and lower overall costs.
“Refrigeration systems have to deliver performance around the clock while managing efficiency and wear on critical components,” said Mike Carman of Invertek Drives. “Variable frequency drives enable equipment to operate only at the speed required. It is a straightforward change that delivers long-term savings and supports more stable cooling conditions.”
Invertek will highlight the Optidrive Coolvert, designed specifically for compact HVAC-R installations and supporting high-efficiency compressors compatible with CO₂ and other low-GWP refrigerants, which are becoming more widely adopted in line with evolving regulations and sustainability targets.
Its small physical footprint allows easy integration within refrigeration racks, display cabinets and OEM platforms without limiting access for servicing.
Reducing compressor start-stop cycles
Continuous but reduced-speed operation during low cooling demand helps minimise compressor cycling - one of the biggest contributors to wear and premature component failure. The technology can also provide additional capacity during peak loads such as frequent door openings or rising ambient temperatures.
Tighter temperature control will be a key talking point at the stand. More accurate motor management helps maintain stable conditions in cabinets and cold rooms, supporting food safety standards and reducing waste.
Options for both panel-mounted and IP66-rated outdoor installations will also be shown, giving system designers increased flexibility.
Easy commissioning and integration
Invertek’s team will demonstrate short commissioning times, built-in protection features and wide communication support for modern building and facility management systems. Technical specialists will be available throughout the exhibition to discuss specific applications and energy-saving opportunities.
The company continues to invest in research and development to support more efficient, lower-impact cooling technologies across global refrigeration markets.
FAQs
How do VFDs improve refrigeration energy efficiency?
By matching compressor and fan speeds to real cooling demand rather than running at full speed continuously, reducing energy consumption and operating costs.
Are Optidrive VFDs compatible with CO₂ refrigeration systems?
Yes. Optidrive Coolvert supports CO₂ and other low-GWP refrigerants used in modern, environmentally focused systems.
Where are Optidrive VFDs used?
In supermarkets, food storage, temperature-controlled logistics and industrial cooling environments worldwide.
How do VFDs support product quality?
More precise temperature control helps maintain safe and consistent conditions, reducing the risk of spoilage and food waste.
