VFD range expanded

Specifically designed for BLDC compressors, heat pumps and condensing units (CDUs), Optidrive Coolvert allows OEMs in the HVAC-R sector to achieve optimal system performance in a compact space. A key highlight is its compatibility with A2L, A3 refrigerants, and CO₂, including R290 and R744 natural refrigerants, supporting F-Gas regulations.

The new Frame Sizes 3 and 4 extend the Coolvert range, significantly increasing output current capabilities:

• Extended power range: Meeting the demands of Scroll compressor manufacturers for higher capacity output, with 400V, 3 Phase output current reaching 30A and 39A in Frame Size 3, and 46A to 58A in Frame Size 4
• Space saving design: The smallest drives in their class, saving valuable space within OEM machines for applications like refrigeration and heat pumps.

These new additions join the existing Coolvert range, renowned for:

• Easiest setup and matching: Only five parameters to set for seamless BLDC/PMAC compressor motor configuration
• Market-leading compactness: Achieved through innovative slim DC link technology
• Flexible mounting options: Through panel mounting and cold plate options for maximum design freedom
• Effortless compliance: No external components are needed to meet EN61800-3-2 / EN61800-3-12 harmonics standards.

“Coolvert is the ideal choice for OEMs seeking high-performance, space-saving solutions for natural refrigerant BLDC compressors,” said Mike Carman, executive business development manager HVAC-R at Invertek Drives.

“These new Coolvert sizes allow our customers to optimise system design and efficiency while complying with evolving global environmental and emission regulations, such as the latest F-Gas requirements in the European Union. The VFDs smaller footprint is particularly valuable for applications where space is a premium, and the extended power range opens doors for new applications.

“Beyond the benefits for OEMs, the Coolvert VFDs are ideal for a wide range of sectors increasingly reliant on energy-efficient and environmentally friendly HVAC-R technology. This includes data centres, supermarkets, industrial process cooling, and building air conditioning systems.”
