Variable Speed Drive CFW701 HVAC

The CFW701 HVAC is a VSD intended for use with asynchronous motors when heating, ventilation, air conditioning and refrigeration applications are to be met, offering excellent effectiveness follows the CFW700 topology.




Launching

Thinking of matching energy savings with speed variation on variable torque loads WEG is now coming with the new HVAC Drive CFW701. Beyond speed control HVAC functionalities like broken belt detection, fireman override mode, dry pump, independent PID blocks, short cycle protection(compressors) are equipping the product. Being conscious of the demand for drives with new functionalities brought by the rapid HVAC market evolution WEG makes available through the CFW701 a PLC code programming environment open for users to make their own macros. By just connecting the computer to the drive with WEG Ladder Programmer (WLP) installed the user is good to go.
