EHT²

WALL HUMIDITY SENSITIVE AIR INLET

Consistency of aeraulic and acoustic performance

The EHT² is the new generation of humidity sensitive wall air inlet. Installed on the wall (100 mm or 125 mm), the humidity sensitive air inlet EHT² is an ideal alternative to window air inlets, offering an answer in case of lack of space on the windows. With accessories, it provides a high level of acoustic insulation, up to 52 dB, which places it among the best performing products on the market. The EHT² also has a multimodal dial where the closed mode allows protection from cold and strong wind. Are available as well the wide open and the humidity sensitive modes.

Distribution of the EHT will be phased out and only the EHT² will be supplied

Please note: Humidity sensitive inlets can only be supplied as part of a whole house DCV solution. NOT SOLD INDIVIDUALLY.

CONTACT-US

Humidity sensitive system: modulates the airflow according to the local relative humidity.

Core drilling: easy installation on the wall, ideal for refurbishment projects.

Acoustic attenuation: up to 52 dB with accessories.

Easy to maintain: no adjustment, simple yearly dusting, and readily accessible filters.

Closing and opening device.

Airflow orientation choice : movable deflectors

Long-lasting material : doesn’t alter with time

Flexibility for comfort

The EHT² has three possible openings for incoming air: two side openings and an opening above the device. By offering the choice of assembly according to the configuration of the room, the EHT² gives more possibility of wall installation. The EHT² can therefore be installed close to the walls without the risk of damaging them or bothering the residents because of the incoming air.

New external canopy

The new and improved standard external canopy is more aesthetic and easier to install thanks to its round design. It has the same acoustic performance than the previous EHT standard canopy AEA778 without acoustic material installed inside. It incorporates a water evacuation gully to drain any water ingress to the external. Supplied as standard with insect mesh pre-installed.

The rain canopy

The rain canopy has a protective parable that blocks raindrops, even in the most extreme conditions. Thanks to this canopy, almost zero infiltration! Aereco wanted to accompany its innovations on the EHT² with a new design, clean and in tune with the times. Indeed, the EHT² fits perfectly into the interior home by appearing space-saving and thin.

Clever insect filters

Clean the insect filter? It’s easy: the EHT² rotates and provides access to two types of removable filter. The F-EHT is easily accessible directly from the duct and the EHT² grid is even simpler from the base of the air inlet!
