Heat recovery units without additional incorporated heater.

CADB/T-HE DI PRO-REG
Heat recovery units with built-in electric heater battery.

CADB/T-HE DC PRO-REG
Heat recovery units with built-in low pressure hot water coil.

The 3-Way valve is provided as an accessory (see accessories table for this series)

Motors
Models 04 to 21: EC motors with integrated electronic protection, IP44, Class B.
Models 40 and 54: Three phase motors, IP55,Class F.

Fans
Plug-fan with backward curved impeller.
All fans installed in CADB/T- HE PRO-REG models, comply with the efficiency requirements of the ErP Directive.

Filters
– F7: Low pressure F7 filters for supply air.
-M5: M5 filters for extract air.

Control
It includes manual or automatic control for modes: adjustable airflow (VAV), constant pressure (COP) or constant airflow (CAV), via CO2, pressure or airflow sensors (accessories).
Post-heating stage versions (-DI/-DC) allow post-heating management depending on the temperatures taken by the temperature probes incorporated in the design.

Ranges of product according to the type of operating control:
VAV- variable air volume
Fan speed can be adjusted with a 0 – 10V signal from the remote touchscreen panel (included) or an external CO2, temperature or humidity sensor (accessories).
CAV – constant air volume
Manual pre-setting of 2 working points the fans are controlled separately. It is necessary to add two pressure sensors TDP-D as external accessory.
COP – constant pressure
Constant pressure measured by an external pressure sensor TDP-S (accessory). It is necessary to add a pressure sensor TDP-S as an external accessory*.
* To control supply and extract air separately it is necessary to install 2 pressure sensors TDP-S.

Additional information
Single phase (CADB-HE PRO-REG) and three phase models (CADT-HE PRO-REG). Airflows from 400 to 5400 m3/h at 150 Pa of static pressure available.
All versions and models include by-pass. Mounting flexibility provided by the interchangeable side panels.
