In 1988, Daniel Lauzon based Danco Télévac Group, a company<br />
specialized in balancing and cleaning ventilation systems.<br />
research, Mr. Lauzon introduces the most complete range of air<br />
of North America.<br />
Our challenge is to establish a relationship<br />
balancing aspects of performance and savings while<br />
enhancing the standards excellence<br />
of our products to improve<br />
quality of life of users. "<br />

Today <strong>NAD</strong> <strong>Klima</strong> produces locally and distributes throughout North<br />
Since then, <strong>NAD</strong> <strong>Klima</strong> is constantly innovating. The company is proud<br />
of many achievements developed with contractors, engineers and<br />
architects.<br />
ment of comfort, air quality and used for the economy of energy.<br />

Induction diffuser<br />
Standard diffuser<br />
• The air helical movement creates a movement of rotation at the output of the diffuser<br />
• It allows an aspiration of the air from the center of the room to the diffuser

ENERGY SAVING<br />
Reduction of the overheating between ceilings.<br />
• Decreasing by approximately 5°C the temperature<br />
differential between the ceiling and the outside.<br />
( Reduction of heat loss by the roof)<br />
Recovery of the ambient heat<br />
• Effective recovery of the heat from the lightning source<br />
• Recovery of the other sources of heat<br />
(computer equipment : ± 20%, occupants : ± 15%)<br />
• Low demand for heating the thermostat thanks to<br />
homogeneous distribution of the heat
Section 4.2<br />
ENERGY SAVING<br />
Energy saving on heat, humidification and<br />
air conditioning of the new air<br />
Reduction of 20% the quantity of new air required per person.<br />
( See section 1 . Improvement of the quality of air according to ASHRAE ; standard 62. 1-2007)<br />
Annual saving of about 2085$ per office area of 15,000 sq.ft
Section 4.3<br />
ENERGY SAVING<br />
Reduction of the overventilation, overclimatisation and<br />
overheating in the central zone<br />
The decrease in the overventilation in the central zones often avoids the overclimatisation and<br />
therefore the overheating to compensate for this one.<br />
(See section 3 ; Reduction of approximately 50% of the central air and ducts in the central areas<br />
by the interpretation of “making induced air”)<br />
Economy of approximately 3 376$ per year for a local of 15,000 sq.ft.

THE FLEXIBLE DUCT DIFFUSER FDD<br />
The induction<br />
• Several holes of various diameters work in obtaining a very high rate of induction.<br />
• The small holes shall ensure that the air propelled to the output of the holes, at high speed,<br />
produce an effect of moving a large quantity of ambiant air around them.<br />
• There is then a heat exchange with the air in the vicinity of the diffuser and FDD,<br />
these temperature differences quickly become isothermal..
