Top 4 - The evolution of compact RTL devices with high energy performance

The compact air conditioner Top 4 is available in three sizes, with a capacity of air handling between 300 and 4500 m³ per hour, and it belongs to a Plug&Play category of devices. Therefore, it's a standard solution developed by Weger on the basis of the innovative design of the DIWER EVO box.

Thus, we present an axial solution for connecting the compartment profiles, a facilitated access system, the thermal cutting, and many other features. The name Top 4 derives from the position of the air intakes that in this series of air handling units are located at the top of the compartment. This characteristic make this product ideal for limited spaces and for reconstruction and restructuring projects.

This model is integrated by series of the following components: a flexible connection with connection compensator on the connection ports, an inspection shutter on the external side and on the air discharge, high-performance pocket filters of glass fiber, EC fans under the rule ErP2015, and a counter-current heat recovery device. Optionally, one can install an automatic heater.

Considerably reduced energy consumption

The energy efficiency of model Top 4 is given by its components. Thanks to the counter-current heat exchanger used by us, you can save up to 90% of energy. While the EC fans reduce the total energy consumption.

Like all our other ventilation units, the Top 4 series is equipped with the Imperia3 smart control system. The only substantial difference with our other models is the unit installation that permits the airflow to pass in a separate chamber.
