Electronic Compressor Control

The L&W ECC (electronic compressor control) is available for all electric motor driven compressors from LW 230 and larger. The ECC replaces the standard electric/pneumatic control and offers the user a range of functions and interfaces only available with digital controls.

The unit has an illuminated LCD display which can show various functions and values as selected on the numeric key board. An easy to follow menu accompanies the user through various menu points. The ECC software can be updated using a standard windows computer via the RS232 serial cable.

The ECC is available in metric or imperial versions and in German, English, French, Spanish, Dutch and Swedish languages.
