Nortec AIRFOG Series - Manual (Page 5)

AirFog Installation Manual | 1
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
Nortec Technical Service Department should be consulted to determine compatibility with the
newer equipment, parts and external interfaces.
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.
AirFog Family of Products
The AirFog family is Nortec 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:
 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:
 AFE Mini: Systems are wall mounted and have 1 or 2 AFE nozzles.
 AFE Octo: Systems are ceiling mounted and available in many configurations including
modulating versions, and have between 3 and 8 AFE nozzles.
This manual describes the installation, operation, and maintenance of all AFE, Mini and Octo
systems.
AFE Principle of Operation
The AFE nozzle uses air flow and the Bernoulli principle to siphon water out of zero psig
