The models of NEXTPOWER range are dedicated to conditioning of medium and wide areas. The intelligent control module optimizes functioning times and supplied power from compressors based on heat load demands in the system.
The range is equipped with R410A refrigerant and features Scroll compressors and plate exchanger.
High reliability is the key plus of NEXTPOWER, thanks to the use of components built in large series and the management of several compressors allowing an increased compressor life span and the reduction of machine stopping risks: a faulty compressor will not compromise the functioning of the unit, that will continue to work with decreased power levels. The optional Air Section Divider allows to service one circuit without stopping the whole unit.
NEXTPOWER obtains high energy yield with high ESEER values and excellent silent
functioning, since the fans adjust their speed to the actual system load, providing benefits
in terms of silent operation, important especially at night.
NEXTPOWER, thanks to the high partialization and the intelligent control module, doesn't require inertial storage tank.
 
The units feature 460V power supply and 60Hz frequency.
