Evaporator

Evaporator

Reduced ice build-up and optimized evaporator temperature leads to lower energy consumption and higher system efficiency. The energy consumption is reduced by always matching capacity to the actual load.

Energy savings and comfort
Fans benefit from dedicated features in VLT® drives.
With the “skip resonance” function you easily identify for the drive which frequencies to pass to avoid frequency noise and damage.
