DEX3000 Air handling unit

DEX3000

Air handling unit

The environmentally friendly, quiet and most effective ventilation solution for schools – equipped with counterflow heat exchanger
DEX3000
DEX3000
A decentralised air handling unit is a simple solution where one air handling unit is placed in each room with separate connection through a wall or ceiling/roof. The simple installation means no need to fit ventilation ducts and other air distributin systems. The DEX3000 units can be installed on an ongoing basis in line with needs and finances, and installation can take place room by room, section by section, without affecting the school’s normal operations.

EXAMPLES OF USAGE

Learn better in fresh oxygen-saturated air

When the air in the classroom is clean, students keep their heads clear and get more out of their lessons. Fresh, oxygen-saturated air boosts concentration, success and happiness. The DEX3000 series is designed to help children and teachers feel comfortable in any classroom. Air quality is really important in classrooms.

During the pandemic, we realised the value of clean air without invisible microorganisms. By constantly exchanging the air, the spread of viruses and bacteria is reduced. This reduces the risk of teachers and students infecting each other.

Perform better at work with oxygen for the brain

At work, many people spend time together in a relatively limited space – often for many hours at a time. A decentralised air handling unit from the DEX3000 series keeps the air constantly fresh, both in the office and in the meeting room. This results in increased attention and performance. Whether you're in a small meeting room or a large conference room, we have a system that cleans the air continuously. Completely silent, of course, so you don't have to raise your voice.

Exercise in fresh air – indoors

When the air in the gym is shared by many hard-working bodies, the air quality drops as weights are lifted. This can be particularly bad in training areas with treadmills, rowing machines and handweights. Here, the air can be so low on oxygen that you can question the effect of the training. With DEX3000 ventilation units, the training experience becomes almost like playing sports outdoors. So welcome to the outdoors - indoors. The technology is easy to install and requires minimal maintenance.

Healthy play and sleep without risk of allergy

Clean air is essential in the institutions where our youngest children play, eat and sleep.

We create the optimum conditions for both children and employees with a DEX3000 air handling unit, perfectly adapted to the dimensions of the room. The unit prevents allergies and promotes a healthy afternoon nap. The little ones get to sleep in peace without the noise of ventilation.

The compact housing is made of aluzink (AZ 185-C4) and is supplied as standard white lacquered (RAL9003). The insulation meets class A2-s1, d0 according to EN 13501.

As an extra option, DEX3000 can be delivered painted in the desired colour at an additional charge.

The unit contains two fans (outdoor air/supply air and extract air/exhaust air). The fan housing contains an impeller with forward-curved blades driven by an EC motor, class IE5 (Super Premium Efficiency). The motors are controlled infinitely variable via the motor control MC.

Heat recovery takes place via a counterflow heat exchanger in aluminium with high efficiency of up to 80%.

The integrated bypass damper is used to direct the outdoor air around the heat exchanger if required, e.g. for temperature regulation, night-time cooling and de-icing. (A heating coil is absolutely necessary for de-icing).
