Self-contained-VSD air conditioners provides the best of the existing technology: compressor with brushless DC motor and inverter that constantly controls speed and delivered cooling power (Variable Speed Drive); reverse blade brushless fan; electronic expansion valve.
• Constant Flow technology fan (i10 and i16 only)
• Twin Rotary compressors Available in three sizes: 10.000 or 16.000 BTU/h max output.

The compressor continuously changes its running speed depending from ambient and set temperature. The compressor operates at maximum power to cool rapidly the cabins, but reaching the set temperature, it reduces the power and electric consumption. In this way it maintains the optimal comfort level with the minimum consumption. The inverter works between 20 and 100 Hz. Self-contained-VSD VELAIR units meet EMC 2004/108/EC directives.

VSD - Variable Speed Drive
The inverter technology, already used in residential air-conditioning, offers the following benefits in marine applications:
• No current peaks during start-up
• Highest energy efficiency: overall reduction of electricity consumption (-40%)
• Perfectly running with small generators or battery powered (through inverter)
• Compressor noise and vibrations almost zero
