HERU Select 1000 TRWT

Floor model with the option to combine top and side connections.
Designed for supply and exhaust air ventilation with energy recovery.
Suitable for installation in larger houses, offices and other premises where high demands are placed on the indoor environment.
High temperature efficiency, low energy consumption (SFP), low sound level, high operating reliability and provides clean indoor air.
Unique design minimizes all thermal bridges.
User-friendly IQ CONTROL with 4.3” touch display for operation and monitoring with the possibility of both wireless and wired communication.
Integrated Modbus communication. No accessories needed.
Easy installation wizard.
Scheduled operation.
Supports use of presence sensors, RH / CO2 / VOC.
Airflow is generated by two silent radial fans with EC motors and impellers with backward curved blades.
The fans are connected using quick connectors and are very easy to remove for cleaning.
A regenerative, non hygroscopic, aluminum rotating heat exchanger located in the center of the unit. The heat exchanger can be disassembled for cleaning.
Delivered with bag filter ISO ePM1 60% as standard, for both extract and supply air. The filters are very easy to change.
Integrated controls for heating/cooling.
Ordered with built-in electric heater or heating coil.
The units inner- and outer casing is made of Al-Zn and meets C4 requirements.
50 mm insulation.
To be installed in a dry area.
The stand can be mounted in two different heights, 138 or 313 mm.
Available in either right-hand or left-hand design.
Delivered in separate sections to simplify transport and installation.

NOTE! The warranty of HERU is only valid if accessories/equipment (e.g. filters) from H. Östberg AB are used.
