Key benefits of the innovative V-Profile humidifier media box: 
 

 

Low Pressure Drop 

 

Hygroscopic Coating 

 

UL 900 Class 1 Rating 

 

High Velocity Performance  

 

Suitable for all Water Quality 

 

No Droplets, Free of Aerosols 

 

 
MHB On/Off Control System  
 

The MH control unit controls the humidity and governs the water management to maximize efficiency. The integrated processor 
with real-time clock controls the air humidity, pre-cleaning sequences, unit purging and water quality control, all fully automatically. 
The controller is designed for connection to building management systems (BMS). This means that parameters such as 
humidifying requirement, water consumption, maintenance requirement or operating hours can be transmitted further via modbus, 
LON Talk or BACnet with 

LINKS2.

 

 

The electronic control cabinet includes electrical fusing and main power switch. 
One, two or three stage control through magnetic staging valves is available. Microprocessor PI-controlled analog humidity signals 
for flexibility. Controlled flushing of the water tank in function of the filling cycles or time controlled drainage through the integrated 
real time clock. Programmable wash cycle for cleaning the humidification media. Automatic flushing of the water lines at the end of 
a season shutdown or without a call for humidity. An automatic forced drain after shutdown periods longer than 72 hours, an 
interruption in humidifying requirement of over 72 hours or in the case of a power failure.
