Topvex TX/C is designed for meeting the coming energy demands with high heat recovery efficiency and low energy use. To guarantee the high heat recovery efficiency the exchanger is designed for low air speed and by that also a low pressure drop. The supply and extract air filter are designed to have a low pressure drop, without compromising with the filtration efficiency. A low internal pressure drop is essential to keep the energy use down Topvex TX/C features Plug fans with EC technology to ensure high efficiency. The EC-motors has when speed-controlled, 15-20% lower energy consumption compared to a standard frequency controlled asynchrony motor.

100% By-pass of heat exchanger secures lowest possible internal pressure drop during the warm season.

A damper isolates the exchanger during the warm period ensures that there is no undesirable heat recovering.

Constant air volume control is standard and Variable air volume control is available as an accessory.

The Topvex counter flow unit TX/C with item name ending -S are pre-configured units with Section defrosting.

The Section defrosting consist of a pre-wired sectioned damper that divides the heat exchanger in three areas plus the by-pass section. All sections are controlled by individual motors for each section and are connected to a separate, pre-programmed control unit.

Section defrosting will prevent severe ice built up in the heat exchanger and allow defrosting of the heat exchanger, while still providing heat recovery through the defrosting sequence.

When activated by pressure detecting, the damper sections will be cyclic operated. Each section will operate in sequence and compensate low temperature in the exhaust air, by modulating the by-pass and section damper.

Topvex is delivered with the new Access control system. The system includes NaviPad control panel, featuring an easy-to-use intuitive HTML5 user interface.

The protection class of the NaviPad control panel is IP54 and 0-50 C° permitted temperature. The enclosure is not UV resistant and the NaviPad is not for outdoor mounting. Communication between the panel and the controller in the cabinet is possible with up to 100 meters of cable.

The NaviPad is connected via 3 meters flat cable. It is mounted on the Topvex unit or on the wall, easy to detach for handheld use.

Relevant operating data and settings are available in real time and can be changed with a few clicks.

Access control has built-in energy saving features like free cooling, cooling recovery, season related temperatures and airflow control.

Possibility to edit names for the unit, the alarms and control components gives the user options to adapt to different installations needs.

With the system overview dashboard it is possible to monitor several air handling units within a local network.

Standard communication possibilities are: Modbus RTU via RS-485 & TCP/IP & BACnet via IP.
