Econox Eco Pair Plus Decentralised HRV Unit SG-ERV-150 Black

The Eco Pair Plus decentralised HRV unit features a reversible DC motor supported by EC technology. The fan is characterised by low energy consumption and quiet operation. The fan motor includes built-in thermal protection and ball bearings for long service life. The unit recovers heat from the exhaust air to preheat or cool the supply airflow. The ceramic regenerator is treated with an antibacterial coating to prevent bacterial growth inside. In addition to the black model, a white version is also available.

F7 Air Filter

Two integrated pre-filters and an F7 air filter are standard fitted to filter both supply and exhaust air. These filters prevent dust and insects from entering the supply airflow and protect the fan components from contamination. The filters are also treated with antibacterial agents. They can be cleaned using a vacuum cleaner or by rinsing with water, without removing the antibacterial treatment.

Energy-Efficient Operation

The fan operates in heat recovery mode and can save more than 30% energy compared to a standard exhaust fan. The heat recovery efficiency of the Eco Pair Plus decentralised HRV unit is up to 97% when the air first enters the unit. It recovers energy within the room and reduces the load on the heating system during winter. It is also an excellent choice for summer, recovering heat and humidity during ventilation to reduce the cooling system load.

Free-Cooling

The Eco Pair Plus is equipped with an intelligent Free-Cooling function—an automatic bypass that allows fresh outdoor air to flow directly inside when the outside temperature is favourable. This provides natural night-time cooling and added comfort, fully automatically and energy-efficiently, without any manual intervention. The Free-Cooling function does not involve a manual valve but activates automatically under suitable outdoor temperature conditions.

Control Options

The HRV unit can be controlled in various ways, including:

Buttons: Several buttons on the unit allow you to switch it on/off and adjust speeds and modes.
Remote Control: Multiple units can be operated remotely, with options to adjust speed, modes, and indicator lights.
Wi-Fi: The unit can be controlled remotely via an app. Besides comprehensive adjustment options, the app also enables monitoring of energy consumption.
