Nortec Industries MH Series - Manual (Page 5)

Models
The Nortec MH Series is available in two basic
versions. The
flOw model with direct water drainage
and the REflow model for water recirculation.
Whether to use a flow or REflow system depends
considerably on the primary application of humidifying
or cooling and the supplied water quality.
The REflow model contains a circulation pump that
conveys the water via EPDM plastic hose to the spray
beam located above the humidifier box. The water
then trickles vertically through the boxes. The water
not needed for humidifying flows back into the water
basin where it is collected and recuirculated for
optimal water efficiency.
In the flOw model, the water is not collected in the
water basin, but is discarded and flows directly into
the drain.

Ultra Violet Sterilization
For applications where higher hygienic requirements must be met an optional UV
package is available. The ultra violet radiation from the discharge lamp sterilizes the
water and controls potential microbial build up. Both Flow and REflow models can
be fully equipped.
Conductivity Monitoring
Conductivity monitoring will continuously check the Total Dissolved Solid (TDS)
content inside the water tank. The adjustable conductivity sensor then initiates
drains accordingly. This feature is available for the REflow models only.
Controls
Nortec offers a wide range of digital controls when selecting the MH product.
The total controller allows easy integration into any local building management
system with it’s host protocol modbus. See Nortec LINKS2 and Online for other
communication options.
