The NAC air curtain acts as a thermal barrier,
considerably reducing energy costs while raising the level of comfort.
NAC - H
The NAC air curtain from NAD Klima is used primarily in industrial areas, warehouses as well as distribution and transshipment centers.
The air curtain is installed either horizontally or vertically depending on the size of the garage door or installation conditions.
Installation of the NAC air curtain ensures that hot or fresh air is kept on the premises regardless of the frequency or duration of time that the doors are open.

Unique design for efficient air distribution
The jet nozzles have been developed by NAD Klima to provide optimal performance of the air jet.
The design allows full projection of the air jet for doors of over 24 feet (7.5m) in height.
The nozzles are also angled towards the door in order to increase the efficiency of the curtain.
Smaller nozzles are inserted between the main nozzles in order to eliminate any infiltration for exterior air.
High performance economical fans
These fans recirculate hot air from the upper part of the building through the spray nozzles.
Energy efficient single or three phase fans are available in 115, 220 or 575 volts.
High quality finish

Mode of operation
The NAD Klima NAC air curtain operates using the principle of hot air recovery
The integrated fans of the NAC recirculate the ambient air under the ceiling and project that air vertically
through the exclusive NAD Klima nozzles to the floor.
This creates a curtain that prevents unwanted elements from entering the warehouse.
The NAD Klima NAC air curtain has dual benefits, not only does it maintain the temperature inside your warehouse,
the air curtain does not require heating because its' principle is based on the recuperation of the heat in the ceiling
by using energy efficient fans.
