High precision air conditioners are ideal for applications where high sensible cooling and close control of
i-NEXT DX
temperature and humidity are required.
The i-NEXT direct expansion air cooled range incorporates full inverter driven BLDC Mitsubishi Electric compressors and a new
R410A Close Control System
microchannel coil remote condenser, perfect for keeping room conditions constant under varying loads, whilst being highly efficient.
Key Features
Perimeter unit with downflow and upflow configurations
Return air temperature operating limits up to 40°C
Full inverter technology with BLDC Mitsubishi Electric compressors
New microchannel coil remote condensers with AC axial fans
Ultralight composite EC plug fans resulting in reduced noise and power usage
Optional Modbus RS485 and BACnet TCP/IP connectivity
Integrated control of up to 10 units for intelligent redundancy management
Optional electrical heater and steam humidifiers
Front access to main components for easy inspection and routine maintenance
Optional floor stands and discharge plenums
Automatic restart from power outage
