Fresh FRX 350 TEH is a high-quality heat recovery unit that is designed and manufactured in Sweden. As a result, it satisfies Swedish requirements in terms of quality, serviceability, and ease of maintenance. It also provides the highest energy savings/energy class. Naturally, it complies with the ErP 2018 Directive.
Controls: Complete with control panel
Heat recovery: Rotor
Postheater: Electric or water heater
Accessories: Shutter, batteries, etc.
Unit with top connection.
The FRX series is made of alu-zinc plate. The casing in insulated with 50 mm mineral wool. The unit can therefore be positioned in cold spaces:
The unit comes with an ePM1 60% (F7) filter for supply air and ePM10 60% (M5) filter for exhaust air. A filter alarm is issued via time in the control panel.
The unit comes with EC motors. The speed is set individually for the supply air and exhaust air fan.
The effective rotating heat exchanger, with efficiency of up to 85%, minimises the need for additional heat. No drainage connection is needed. The unit tries to reach the desired temperature via the rotating heat exchanger. If this is not enough, the built-in electric postheating battery or the external water battery covers the remaining need. A complete accessories package if available for the water batteries for effective control.
The unit can be controlled based on supply air regulation, with or without outdoor air compensation, or exhaust air regulation. In the summer, when heat recovery is not required, the rotor stops and thereby provides cooler air to the property (free cooling).
