Pre-configured air handling units with high-efficiency
counter flow heat exchanger - BLS CF

The BLS CF floor-mounted series of air handling units with horizontal duct connections offers a high-performance and optimized solution, available in multiple sizes to accommodate a wide range of airflow requirements. Five pre-configured ventilation unit options allow for a quick selection of the most suitable variant, significantly speeding up the equipment delivery time.

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.

Sizes and capacities of BLS units

Modular design allows:

combining sections fast without leakages;
optimizing manufacturing time;
making transportation easier.

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.
