Invertek Drives Ltd’s new Coolvert variable frequency drive (VFD) is one of the smallest in its class, providing OEMs with opportunities to reduce panel space and lower machine costs.

Launched at Chillventa 2018 (Hall 5, Stand 205, 16-18 October 2018) the VFD was unveiled alongside a new CO2 condensing unit controller from Danish company Reftronix ApS.

Coolvert is designed specifically for OEM’s where space is at a premium.

It also has the widest ambient operating range of between -20c to +60c making it ideal for use in a wide range of environments.

Coolvert 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.

Its open Modbus RS485 communication ensures a seamless connection to any external application controller, allowing the OEM freedom to select which components to use which again helps lower manufacturing costs.

With an IP20 rated front and an IP55 rated rear, 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 Carmen, International Business Development Manager at Invertek Drives Ltd.

“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.”
