New VFD for CO2 systems


10 September 2018
A new variable frequency drive (VFD) designed for CO2 refrigerant systems is to be launched by Invertek Drives at Chillventa 2018 in Nuremberg next month.
The VFD will be launched as part of a partnership with Danish company Reftronix,  who will be introducing a new CO2 condensing unit controller to be used with the VFD. Both companies will be sharing a stand at the show (Hall 5, Stand 205).
The technical partnership is said to provide an energy-efficient, natural refrigerant-based solution to comply with the requirements that the EU’s F-Gas Regulation and Eco-Design Directive imposed on the HVAC&R industry. It will also use IOT technology to provide remote, secure and efficient management and monitoring of such systems.
The companies predict energy efficiency gains of at least 25% with the controller and VFD compared to a traditional ‘on and off’ control.

Mike Carman, international business development manager at Invertek Drives,, said: “The CO2 refrigerant market is proliferating as tougher and more stringent EU F-Gas regulations come into force. Our technical partnership with Reftronix, with the combined VFD and CDU controller to be revealed at Chillventa, will provide an energy efficient solution for OEMs within the refrigeration sector.”
