Leading Humidification Innovation... Once Again

Nortec's GS Series Condensing High-Efficiency Humidifier

The Nortec GS gas-powered steam humidification system is the industry’s first fully condensing and efficiency-leading humidifier.

With over two decades of experience in manufacturing gas-fired humidifiers, Nortec always strives to build on past inventions to create new and true innovation that embraces design and functionality. The latest GS series highlights every single one of Nortec’s high priority objectives and customer values while incorporating them all into our most efficient series so far!

Combining eco friendliness with cutting edge technology.

The continuously rising costs associated with electrical power have created an ever growing demand for gas-fired technology which provides a very cost effective and environmentally friendly option with regards to humidification.

For these reasons, Nortec has been striving to develop a new gas-fired humidifier which uses the more economical natural gas and which also operates under the high-efficiency classification.

Nortec is proud to present to you: the GS Condensing System (CS) model which provides substantial condensing efficiency with an average of over 90%. 

Another available option from our GS Series is the Low-Emissions (NX) model which was created to exactly meet California’s emission regulations. The GS presents a high value model due to the ease in both operation and installation while guaranteeing a fast payback for High-Efficiency upgrades.

Installation Savings

The most noticeable saving when installing a new GS series will certainly be the use of a CPVC venting option. As a perfect alternate option to stainless steel venting, the CPVC is incorporated in both the CS and NX models supporting the reduction of exhaust temperatures of 140°F/60°C.

This results not only in easier operations but also allows for reduced time in pay back periods due to installation costs being greatly reduced as well.
