Improving energy efficiency in demanding applications

WEG has developed IP55-rated enclosures for its CFW701 variable speed drives (VSD) to help users in the process industry adopt more energy-efficient strategies while meeting stringent hygiene and endurance requirements.

Both VSD series - in frame sizes B to E - are now available with enclosures that effectively protect electrical components against water jets, dust and corrosion and as such are suitable for process applications in the food industry or for especially harsh environmental conditions. As a result, users can be confident that their VSDs reliably operate, providing long service life with reduced downtime.

The IP55 enclosures feature an improved cooling system, which ensures that the VSDs continue to operate reliably even under full load. They are suitable for direct wall mounting and are designed to protect devices against infrared radiation, meaning that the corresponding drive units can be used even in extremely harsh environments. Additionally, EMC filters as well as control panels with a USB port are integrated in the enclosure to ensure ease of use and programming.

WEG’s variable speed drives with IP55 rating have the same functionality as the standard devices in the CFW701 series, which provide reliable and energy-efficient control of motors. Users can integrate matching extension modules for inputs and outputs, communication protocols and temperature monitoring features according to their needs. A power switch can also be fitted as an option.

The IP55 enclosures are available for frame sizes B to E of the CFW701 series, which is designed for the HVAC sector. They cover the voltage range from 220 to 480V and the power range from 5.5 to 110kW.
