Nortec AirFog Installation Manual |

Introduction
Applicability
This document is applicable to all Nortec AirFog system components purchased after February
2004. If the designer has existing system components purchased prior to February 2004, the
Condair Technical Service Department should be consulted to determine compatibility with the
newer equipment, parts and external interfaces.
Nortec AirFog Humidifiers
Nortec AirFog systems use the nozzle humidification technology of injecting droplets of cold
water directly into the air. This method of humidification has the following advantages over
steam humidification:
Lower frequency of maintenance.
Systems are mainly mechanical (water pipes and air pressure) with only a 24 VAV power
requirement in the control panel.
A “no cost” air cooling benefit due to latent heat of vaporization extracting heat from the air.
Maintenance is primarily focused on keeping the air compressor operational.
Change of components is fast and requires minimal system disassembly.
Nortec AirFog Family of Products
The Nortec AirFog family is Condair most advanced adiabatic humidifiers. There are groups of
products that fall in this family: applied products and packaged products.
The applied products group describes systems that are tailored specifically for each application:
Nortec AFE Nozzle systems use compressed subsonic air flows and water to create a fine
mist that is sprayed directly into a space.
The packaged products group describes systems that are ready to operate out of the box, and
need only be connected to power, air, and water. These products include:
Nortec AFE Mini: Systems are wall mounted and have 1 or 2 Nortec AFE nozzles.
Nortec AFE Octo: Systems are ceiling mounted and available in many configurations
including modulating versions, and have between 3 and 8 Nortec AFE nozzles.
This manual describes the installation, operation, and maintenance of all Nortec AFE, Nortec
Mini and Nortec Octo systems.
Nortec AFE Principle of Operation
The Nortec AFE nozzle uses air flow and the Bernoulli principle to siphon water out of zero psig
Note:
Prior to installing any Nortec AirFog product carefully READ through this entire
guide, it contains valuable information, which will assist in all aspects of the
installation.
