CERA units | type NXOJOOB
Technical information
Application
- CERA units are pressure-independent fresh outside air volume control
units (ventilation units) suitable for stacked housing. The units have
been designed particularly for systems with low noise criteria and for
the accurate measurement and control of air volumes courtesy of the
patented air flow sensor type Flo-Cross
®
.
The CERA unit controls the amount of fresh air supplied to the room
based on the measured CO
2
level and features override options using
switches, all of which save energy. The CERA unit controls the amount
of fresh air supplied to the room based on the measured CO
2
levels
between a factory calibrated minimum and maximum set-point. It will
provide increased air volumes when the ‘cooking’ function or ‘bathroom’
function is activated. When the ‘night’ function is active it will provide
reduced but suffi cient fresh air for the occupants. This way the CERA
is a very energy conscious system, which will contribute to your green
building certifi cation.
The units take up very little space and are suitable for use in new or
refurbishment projects (renovations/transformation). The units are
maintenance free and do not contain fi lters or a fan.
BENG calculation
BENG stands for Nearly Zero Energy Buildings and is applicable since
01-01-2021 and did replace the EPC calculation. The BENG calculation
is required for applying for a new building environmental permit and
calculate the Energy Performance component.
The energy performance of a building is determined with the new
determination method NTA 8800.
Technical information
The compact, low-noise units are internally lined; the air fl ow does not
come into contact with the insulating material and the units do have
supply and return spigots. The supply and return air run synchronously
with each other and ensure air balance in the apartment. Two versions of
the CERA system are available: the one-zone system (CERA-1) and the
two-zone system (CERA-2).
The CERA-2 unit has an extra air damper which controls the air fl ow
more accurately between the diff erent rooms. On the air side, it features
a specially-designed servo-actuated 3-way valve that directs air to the
main zones & the sub zones depending on the need.
The CERA PLUS system can be connected to several CO
2
sensors for
several bedrooms and/or other rooms. The highest CO
2
value measured
will be used in the air volume calculation. The CERA PLUS system is
available for the CERA-1 (up to 5 sensors) and the CERA-2 (up to 6
sensors).
The units and the system are not suitable for direct connection to
a motorless or motorised kitchen hood.
