VENT HEATING ELEMENTS eVA125

Vent heating elements are used in areas with modern home ventilation technology employing heat recycling and provide incoming air re-heating directly at the inflow opening of the respective room.

Within an HRV system, they assume the remaining heat needs for the

entire heat output during the cold periods - with individual room control.

They are used in simple ventilation systems to avoid cold air drafts.

PRODUCT DESCRIPTION

Connection housing

Outer collar

Air velocity attachment

Heating element attachment

Disc attachment

Annular gap restrictor

The connection housing is for the connection of air lines and the power supply as well as for accommodating the heating element attachment. The electrical cable line lies outside the air pipe.

It is attached in a 125mm air pipe using tension wedges.

CONNECTION HOUSING

Multipoint connector for connection to the power supply incl. cover

i

Screws (3x) for using the tension grips

i

Straight edges with groove marks for alignment

i

Cutting mark for cutting off the connection pipe

OUTER COLLAR

The outer collar assumes the airflow together with the disc vent attachment and the

characteristic bezel with disc vent - alternatively with air velocity attachment.

The outer collar makes flush installation possible on the attachment level

or a shadow joint setting.

DISC ATTACHMENT

The disc vent attachment with an air outlet angle of 360° is used for ceiling mounting. The disc attachment has lock positions through which the air outlet gap can be set in 1mm graduations.

Hollow back for mounting on heating element attachment (5 lock positions)

Reproducible setting through the use of graduated grooves

AIR VELOCITY ATTACHMENT (SLOT BEZEL)

Window for reading the

setting positions

i

Preset breaking point B-B for reducing the RSB by 30°

i

Preset breaking point A-A for reducing the RSB by 30°

i

In the case of wall mounting of the vent heating element, the velocity attachment with a slot bezel is used. A relatively large air velocity can be attained through restriction of the outlet slot.
