Vertical heat recovery ventilation units with top connections and counterflow heat exchanger – BLS CFV

The BLS CFV floor mounted series of air handling units provides a cost-efficient and space-optimized solution, available in multiple sizes to accommodate a wide range of airflow requirements. Vertical duct connection alows to optimize air duct arrangement. The compact design, along with dividing larger units into sections, facilitates easy transportation to the installation site. The Slim version is specifically designed for customers with unique installation depth needs, boasting a total unit depth of only 680 mm for these models.

Only 680 mm of depth for Slim version allows for placement units in any location.
Optimized connections facilitate low air velocity, resulting in reduced noise levels.
Featuring counterflow heat exchangers, ensure high efficiency while minimizing leakage.
Casing with 50 mm insulation to ensure low noise levels.
Casing made of AlZn, with an optional coating for enhanced corrosion resistance.
Externally mounted connection box, containing all wiring and electrical components, enabling quick and easy connection.
Main heaters are located inside the units for easy maintenance (excluding the Slim version).
A wide range of duct accessories (pre-heaters, post-heaters, coolers, connection reducers, flexible mounts, extra filtration, silencers, etc.) to meet any customer requirements.

Improved design with better performance

T2 / TB2 / L1 / D1

The construction of the case with a PVC profile ensures the absence of thermal bridges, minimizes heat loss and reduces the noise level.

Integrated control system

Plug-and-play unit: full electric wiring

Additional option – full factory electric wiring includes:

Installation of air damper actuators. Routing of contacts from actuators to the terminal box.
Installation of differential pressure switches in filter sections. Installation of a relay actuation threshold to the necessary level (final pressure drop according to the selection).
Installation of frost protection thermostats in water heating coils sections.
Installation of the VFD in the rotary heat exchanger section.
Installation of bypass damper actuators in the plate heat exchanger section.
Routing of all electric contacts in the electric heater sections.
Routing of all electric contacts in the fan sections.
Installation and adjustment of all temperature and humidity sensors inside the unit.
All the electric contacts are routed to the junction box, which is mounted in one of the sections.
Plug-and-play option implies the possibility of shipment in separate blocks. In this case, joints and connection boxes are installed between the sections.
