Housing with increased comfort

Flats built today are becoming more and more energy-efficient. Houses are becoming more compact and often have large glass surfaces. This leads to a warmer indoor climate.

To achieve a better indoor climate, our integrated air handling unit, EcoCooler, can be selected for the centrally located air handling unit Envistar Flex.

The cooling unit lowers the temperature of the air supplied to the flats. On a warm summer’s day, the temperature supplied to the flats can be lowered by 6–10 degrees. If the door to the bedroom – into which the air is often supplied – is closed, a cool and comfortable indoor climate will be achieved.

Installation cost for EcoCooler approx. € 450/flat

Running cost for centrally controlled supply air approx. € 15–25/flat/year

The temperature drop in each flat depends on solar gains, air flow and internal loads. This means the heat that is generated in the flat in the form of people, lighting, cooking, computers, etc. The inlet temperature is controlled centrally and cannot be controlled individually in each flat/room.

Through product development, we are constantly improving energy optimisation in our air handling units. As part of this work, the range has been fitted with well-designed casing with a good fit and high energy performance.

Doors and panels are manufactured in double sheet metal construction of aluminium/steel zinc-treated steel sheeting with ALC protective coating, which complies with the requirements for corrosion class C4. Some parts of the unit can be manufactured in different materials, e.g. stainless steel 2343.

The product selection program IV Produkt Designer offers the option to choose cabinets and panels in fire class IE30.

Innovative solutions mean we can offer units with very low heat loss. According to the EN 1886 standard, the classification of the casing is determined by the U value. The lower the number, the better the insulation capacity.

ThermoLine

Multiple versions of the casing are available. The standard version is classified under casing class T3, which has a U value of 1.24*. For the best energy performance, you can now also choose ThermoLine, which is a class T2 casing and has a U value of 0.88*.

A casing class of T2 reduces cold bridges. In fan rooms with high air humidity, this reduces the risk of condensation forming on the unit casing.

The black plastic insert in the profile breaks the cold bridge and is characteristic of the ThermoLine – T2 casing.

* Measured in model box in accordance with EN 1886

We protect resources

Air that is extracted via ventilation systems often contains a lot of heat. We do not want to let this heat go to waste and aim to recover as much of it as possible. We do this by using various types of heat exchanger. We recover the heat from the extract air and use it to heat the cold air from outside.

More and more people are choosing counter-flow heat exchangers for housing projects because there is no risk of odour transfer between supply and extract air. Our counter-flow heat exchanger is equipped with a unique, patented defrosting technology – ODS. This ensures the highest possible annual efficiency without the risk of the exchanger freezing and being blocked with ice.

Bear in mind...
... that counter-flow exchangers and rotors should be adapted and tested for homes.

Optimised performance

The series is available with a wide selection of direct-driven fans and motors in order to optimise the efficiency of the fans and minimise electricity consumption. Each fan impeller and motor is balanced and test-run together to guarantee function, ensuring a long service life.

The direct-driven fans are intended for variable speed control. Fan impellers have airfoil blades and rotating diffusers, which gives low noise and high efficiency.
