Do more with less

There’s something about UFAD system air

that just feels right. Optimization of energy and

space, faster construction time, more flexibility.

Underfloor air distribution system1. Energy saving

UFAD reduces energy consumption by over 20% compared to traditional overhead systems thanks to:

• Lower fan pressures required to deliver air in a room

• Warmer supply temperature because air is supplied close to occupants and not from the ceiling

• Efficient supply/return air flows that prevent short cycling of the supply air back to the returns

2. Comfort

The increased well-being of office occupants translates to a more productive working environment:

• The natural convective flow activated by the human body heat moves the conditioned air up, pulling CO

2

and humidity toward the return plenum

• Unlike overhead systems, UFAD system air is always supplied at a comfortable temperature, without high-speed air jets

• A closer temperature control can be obtained by installing air boosters in separate rooms or in areas exposed to solar radiation

3. Flexibility

• System components are integrated into the modular access floor without the use of ductwork, this way they can be easily moved to accommodate changes in the room layout

4. Increased available space

• The height of each floor can be reduced by 10%; for example, a 40 m high building can have 11 floors instead of 10

• The access floor plenum is not only used for air conditioning but also other infrastructure, like electrical and hydraulic systems

5. Faster construction time

• No need to build dedicated ductwork as the ceiling and floor plenums are used as air ducts

• The system design and construction is faster: 40% of time is saved compared to traditional solutionEnergy Flexibility Time Comfort

Whatever your UFAD concept, we have your solution

UFAD system uses the space between the structural

concrete slab and the underside of a raised access floor

to deliver conditioned air directly into the occupied zone of

the building. This principle can be developed in different

configurations according to the customer’s needs and

project requirements.

1

2 Zero-pressure configuration

In this configuration the central air handling unit delivers conditioned air to the underfloor plenum, but in this case the plenum is maintained at very nearly the same pressure as the conditioned space. Active fan-powered diffusers supply the air into the occupied zone of the space.

1 Pressurized plenum configuration

This configuration consists of an air handling unit delivering air through the underfloor plenum, maintaining a pressure that allows air to be delivered into the space through passive floor air diffusers.

Fan-powered air diffusers (UTCT) can be integrated in closed meeting rooms and offices where the temperature requires rapid and personalized adjustments.

Chilled water AHVS range

AHVS units treat and distribute the cooled air under the access floor. This compact and very low noise unit, normally located in a technical room, mixes fresh air with ambient return air. Thanks to the bypass on return air, it allows perfect temperature control of the supply air and energy recovery.

Chilled water TDCV LN range

This compact and very low noise unit can be placed in technical rooms, aisles, or in the working space. Fresh air is provided by an external air handling unit. The internal TDCV unit mixes the fresh air and the ambient return air, cools or heats it, and delivers it under floor at the desired temperature conditions.
