ABOUT DEHUMIDIFIERS
THE SOLUTION
THE BRAIN OF THE SYSTEM
NX-ERA XPRESS
BENEFITS FOR THE CUSTOMER
• The PLC control system allows significant improvements in control and
environmental air efficiency.
• The PLC is used as a reference for PID control- important to the user to know
how is the operation of the equipment and make necessary changes
according to the need of the process.
• High reliability for continuous and steady operation with constant air purity.
Plant availability time is better than 90 - 95% always.
• The only utilities required is electrical power. Smart control of humidity
ensures energy savings.
