NEXT EVO INV air conditioners form a range of machines featuring advanced hi-tech characteristics, designed for a variety of applications, subject to strict requirements in terms of control of internal environmental conditions, continuos operation, reliability and energy saving.

The fields of application of the NEXT EVO INV air conditioners are especially suited for the following applications:
  • EDP centres, telephone exchanges, ups rooms, transformer room etc.
  • Control towers, control rooms and switchrooms, libraries, museums, controlled contamination rooms.
  • Rooms characterized by high sensible thermal loads and negligible or absent latent loads, TV and photographic studios, specialist therapeutic treatment or analysis centres in the healthcare sector.
  • Particular buildings in the commercial sector, such as shopping centres, post offices, bank branches, show rooms etc.
The compressor driven by an inverter varies the load continuosly and the regulation of the refrigerant circuit can be easily adapted to the operating conditions required.
  • The working range of NEXT EVO INV varies on average from 35% to 120%.
  • The machines are suitable for indoor installation only. 
  • The constructive solutions and the internal lay-out allow high application flexibility and the frontal access to the main components for the inspection and routine maintenance. 
  • Machines supply fully assembled with refrigerant charge and control systems. The installation requires electrical and hydraulic /refrigerant connections only allowing high costs and time reduction. 
  • Final assembly on all machines before shipment including running test, reading and monitoring of operating parameters, alarms simulation and visual check.
