Compact heat recovery unit with high-efficiency (up to 93%) counter-flow heat exchanger EUROVENT certified. The casing is made from plasticised galvanized steel in white. Panels are double skinned with thermo-acoustic flameproof insulation (A1/M0), made from 25 mm thick fiberglass in false ceiling versions (Models 04 to 33) and 47 mm in outdoor versions (Models 45 to 100).

Configurable and airtight supply and exhaust spigots, suitable for horizontal and vertical installation. Minimum outdoor temperature -10ºC. For lower temperatures it is necessary to use preheating batteries located in the outdoor air inlet.

Offers a robust construction, versatile assembly, easy maintenance and condensate tray (models 04-33 PRO REG).

Consult technical literature for performance values including airflow, connections, efficiency (>85%), fan speed and unit weight etc.

Versions available:

Horizontal and vertical configurations, without additional heat, electric battery included and water coil included units.

Single phase (CADB-HE PRO-REG) and three phase models (CADT-HE PRO-REG). Airflows from 450 to 10 000 m³/ hour.

- CADB/T-HE D PRO-REG

Heat recovery units without additional incorporated heater.

Motors:

Models 04 to 33: Single phase EC motors with integrated electronic protection, 230V/I/50-60Hz IP44, Class B. Models 45 to 100: Three phase EC motors with integrated electronic protection, 400V/III/50-60Hz IP 54 class B.

Fans:

Plug-fan with backward curved impeller.

Filters:

F7: Low pressure F7 filters (ePM1 70%) for supply air.
M5: M5 filters (ePM10 50%) for extract air.
Possibility of mounting a second filter inside the unit (accessory).

It is possible to complement the heat recovery unit with a specific range of water and direct expansion coils. Also available, the exclusive module IAQ with a high efficiency in the retention of pollutants associated with outdoor pollution (gases and particulate matter), providing adequate quality to the supplied air, even in polluted outdoor environments.

Control:

It includes an integral operation control, from factory assembled and wired to all the components included in the unit (fans, by-pass, filter pressure switches, temperature probes, etc.). Allows fans control in manual or automatic mode with the display of supply and extract real air volume in all the operation modes (fans pressure transmitters included): Variable airflow (VAV), constant pressure (COP) or constant airflow (CAV) (Available accessories for each mode). Also allows the management of heating coils (DI and DC versions). Integrated air and water temperature probes.

Description of the fan control modes which can be configured:

VAV- variable air volume Fans speed can be regulated by a 0 - 10V signal from the remote touchscreen panel (included) or an external CO2 , temperature or humidity sensor (accessories).
CAV - constant air volume Fans speed are automatically adjusted in order to maintain a constant airflow regardless of the filters fouling. Supply and extract fans are controlled independently allowing the configuration of different airflow values for each one. No accessories are required.
COP - constant pressure Constant pressure measured by an external pressure sensor TDP-S (accessory). Appropriate control mode for multi-room installations with flow control dampers
