Nortec's All New Electric Outdoor Humidifieres

Nortec’s EL and RS Series of electric steam humidifiers lead the humidification industry in performance, reliability and flexibility. 

Application flexibility of these products has now improved even further with the addition of the newly designed outdoor cabinet models. 

The EL-OC and RS-OC are now the most compact, easy to maintain and cost effective outdoor electric humidifiers on the market. Many new outstanding improvements allow this product to be used in almost any application requiring reliable humidification.

The EL-OC and RS-OC humidifiers have been fully tested and approved for operation in a wide range of climates between -40˚F (-40˚C) and 104˚F (40˚C) to meet or exceed all competitors.  The heavy-duty weatherproof cabinetry has been certified to an IP54 rating (NEMA 3 equivalent) for reliability in almost all outdoor environments.

The integrated cabinetry of the EL-OC and RS-OC allows for the smallest footprint of any other outdoor humidifier on the market. All three cabinet sizes can fit through a standard doorway for easy maneuverability and occupy minimal floor space.

Installations of these new products are as easy as ever, requiring only a single electrical connection to the unit in addition to standard plumbing lines for supply and drain water. Internal drain water cooling allows for the unit to be installed directly to a drain line without the need for additional external cooling.


Much like the Indoor EL and RS models, the new Outdoor line is equipped with the touchscreen Integrated Controller for a powerful and user friendly experience. Connectivity to Building Management Systems (BMS) still come standard with every unit through BACnet MSTP (Slave), BACnet IP, Modbus and Lonworks. 

In addition to BMS connectivity, every unit also comes standard with Remote Fault Indication relays allowing for remote monitoring of the humidifier’s status. Remote Interface is another powerful tool available for these products which allows for full remote access to the humidifier’s Integrated Controller at your computer anywhere in the building! These features can be particularly critical for outdoor mounted units which may be mounted in less accessible locations.


The EL-OC uses long lasting, high performance and hygienic steam cylinders which are replaceable when required. The cylinder is the heart of the humidifier and is where the boiling action takes place. Replacing the cylinder is quick, simple, and allows the humidifier to operate just like new!

The RS-OC Scale Management option is an innovative, market leading technology which significantly reduces maintenance time and effort. With the selection of the Scale Management option, a separate Scale Collector reservoir is installed below the main boiling tank, and the boiling tank itself is fitted with an internal liner allowing for cold pool technology. At each small maintenance interval, the Scale Collector can simply be removed, emptied, and reinstalled in minutes. The EL-OC and RS-OC are equipped with freeze protection valves for fail safe emergency drain.

Thanks to these maintenance innovations, the EL and RS Series have the fastest and easiest maintenance in the industry, even in bad weather. This leading serviceability significantly saves on maintenance fees as well as down time to the unit.
