HR300 RW6

Description

Overview

The HR300RW6 is a semi-remote unit designed for mounting in an external wall.Two 150mm diameter spigots are provided for ducting connection to internal supply and extract grilles. The unit provides balanced supply and extraction with up to 70% heat recovery. Controlling internal relative humidity, the HR300RW6 unit controls condensation and eliminates mould.

Fresh pre-warmed air from outside is continually provided to the room with simultaneous extraction of stale air and smells. Heat is transferred via a unique plastic heat exchanger from outgoing air to the fresh air supply with zero cross contamination, maintaining internal temperatures and providing a fresh environment.

Available in three speeds: 75, 210 and 280m³/h. It is ideal for offices, changing rooms and examination rooms, etc.

 

Installation

HR300RW6 Typical Installation

The HR300RW6 is designed for installation in an external wall providing (150mm) diameter spigots on the inner plate for ducted extraction and fresh air supply. The unit requires a 280mm wide and 380mm high hole and is mounted through the wall in a vertical position.The HR300RW6 requires a minimum overhang of 70mm on the outside and 50mm inside. Units should be level to assist in-built condensate drainage.
