VELAIR 21K BTU VSD 230V MARINE AIR CONDITIONER UNIT I21VSD 230V

21K BTU VSD 230V Marine Air Conditioner Unit Brushless Variable Speed Soft Start Reverse-Cycle Heat

Self-contained-VSD air conditioners provide the best of the existing technology: compressor with brushless DC motor and inverter that constantly controls speed and cooling power delivered (Variable Speed Drive); reverse blade brushless fan; electronic expansion valve; R410A refrigerant.

Three sizes available: 10.000, 16.000, 21.000 and 27.000** BTU/h. The inverter technology, already used in residential airconditioning, 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
• Compressor noise and vibrations are almost zero
• The constant temperature of the airflow
• Wi-fi connection for smartphones available through a dedicated app

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