21K BTU VSD Smart 115V Marine Air Conditioner Unit Brushless Variable Speed Soft Start Reverse-Cycle Heat
Self-contained VSD air conditioners provide the best existing technology: compressor with brushless DC motor and inverter that constantly controls speed and delivers cooling power (Variable Speed Drive); reverse blade brushless fan; electronic expansion valve.• Constant Flow technology fan (i10 and i16 only)• Twin Rotary compressors• 21.000 BTU/h max output.
The compressor continuously changes its running speed depending on the ambient and set temperatures. It operates at maximum power to cool the cabins rapidly, but once it reaches 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.
