1 HERU 90 LP EC HERU 90 LP EC Energy recovery unit with low profile and side connections. Designed for supply and exhaust air ventilation with energy recovery (FTX). Suitable for installation in homes, offices and other premises where there are stringent requirements on the indoor environment. High temperature efficiency 82%, low energy consumption (SFP), low sound level, high operating reliability and provides clean indoor air. Unique design minimizes all thermal bridges. For easy handling, the unit is remotecontrolled using the wireless control unit for operation and monitoring. Comes equipped for Modbus counication via RS485. irflow is generated by two silent radial fans with EC motors and impellers with backwardcurved blades. The fans are connected with quick connectors and are very easy to remove for cleaning. regenerative, nonhygroscopic, aluminium rotating heat exchanger located in the centre of the unit. The heat exchanger can also be removed for cleaning. Comes with F7 panel filter as standard, for both exhaust and supply air. The filter is very easy to change. Integrated controls for heating/cooling. vailable with or without integrated electric heater. The unit is constructed of doublelayer galvanized steel sheet with insulation in between. For placement in warm areas. Ideal for mounting in small spaces such in the ceiling. Comes as righthand version as standard. NOTE! The warranty of The HERU is only valid if accessories/equipment (e.g. filters) from H. Östberg B are used. PRODUCT: HERU 90 LP EC RTICLE NR: GENERTED BY ÖSTBERG PRODUCT DTE: 4 March :4 M
