VFD specifically designed for CO2 refrigerant condensing systems

VFD specifically designed for CO2 refrigerant condensing systems

A new high-performance variable frequency drive (VFD) designed for OEMs to optimise the performance and the lower the energy costs of BLDC compressors used in heat pumps and condensing units has been launched by Invertek Drives. The new Optidrive Coolvert is one of the smallest in its class, providing machine builders with opportunities to reduce panel space and lower machine costs. Designed to operate specifically with CO2 refrigerant condensing systems, it can provide end-users with energy savings of up to 25 per cent.

For use in applications involving CO2 refrigerant systems, Coolvert is targeted at OEMs to help meet the EU F-Gas (Fluorinated Greenhouse Gas) regulations, in addition to energy efficiency gains. It is said to have the widest ambient operating range in its class of between -20c to +60c, making it ideal for use in a wide range of environments, including retailer chill and freeze refrigeration systems.

It is compatible with all motor types, including induction motors, permanent magnet motors, brushless DC motors, synchronous reluctance motors and Line Start PM motors ranging between 1.5kW to 11kW, 2HP to 15HP. It has single and three-phase input of 200V to 480V. Coolvert’s open Modbus RS485 communication ensures seamless connection to any external application controller, allowing the OEM freedom to select which components to use, leading to lower manufacturing costs.

With an IP20 rated front and an IP55 rated rear, its through-panel mounting allows the drive’s power electronics to be cooled by the chilled air of the condenser. This allows OEMs to select the smallest panel size for the control of the electronics, while removing heat generated by the drive and maintaining the IP rating.

“Coolvert’s wide voltage and power range and open RS485 Modbus serial port allows the OEM to seamlessly connect any manufacturer’s application controller to the drive,” said Mike Carman, Head of Sales at Invertek Drives. “Its compact design, one of the smallest in the market, makes it an ideal solution for machine builders who have limited panel space and want complete system design flexibility.”

He added: “The retail refrigeration and freezer market is an example of where significant savings in energy costs can be made using Coolvert, in addition to ensuring refrigeration manufacturers are able to meet the EU F-Gas regulations.”
