Nortec ME Series Evaporative Humidifier and Cooler

Humidification and Evaporative Cooling humidity.com Evaporative module Touch screen control panel Potable or RO treated water is pumped to A touch-screen control panel with the top of the evaporative module and intuitive interface allows software- flows down the corrugated surfaces of based commissioning and has detailed the evaporative cassettes. As air passes operational, servicing and fault through the module it is humidified and displays. A USB connection allows cooled without droplets. Evaporative software updates and downloading of modules are custom built and can range history reports. The system can also in size from 24” - 118” (600 - 3,000mm) wide connect to BMS. and 25” - 118” (625 - 3,000mm) high.

Interior or exterior hydraulic unit The patented self-contained hydraulic unit can be fitted inside or outside of Temperature & conductivity sensor the duct, providing access to all Routine hygiene flush cycles can be mechanical components without timer controlled or activated by having to enter the AHU. optional temperature and conductivity sensors. This prevents wastage of water by ensuring flushes only occur when necessary.

Multi-stage pump system Up to five 24v DC electronic pumps, with magnetic driven impellers, offer up to five-stage control as standard and enable adjustments from the control panel without any mechanical alterations to valves. Operating energy consumption is proportional to output with the complete system operating on just 85-278W.
