RECOM 6 S

Product Description

The RECOM S/SE EC series of ventilation units are engineered as high-performance and energy-saving solutions, designed to ensure an optimal indoor microclimate in larger spaces. These advanced aggregates not only meticulously filter air but also guarantee a powerful and continuous supply of fresh air, efficiently removing stale air. The RECOM 6S EC model utilizes a high-capacity polystyrene counterflow heat exchanger, allowing it to achieve an exceptionally high heat recovery efficiency of up to 92%. This ensures a significant reduction in heating costs even with high ventilation demands. Modern EC fans operate quietly, efficiently, and economically. The unit is ideally suited for efficient ventilation of larger private homes, cottages, or commercial premises and connects to Ø200 mm diameter ducts, boasting a high A+ energy efficiency class.

Key Features:

• Robust Casing and Vertical Installation: Made of high-quality steel with a durable polymer coating. Internally lined with a standard 40 mm thick layer of mineral wool, ensuring excellent heat and sound insulation even at high airflows. Designed for convenient vertical installation.
• High-Capacity Counterflow Heat Exchanger: The RECOM 6S EC model integrates a polystyrene counterflow heat exchanger optimized for larger air volumes. In the cold season, it efficiently transfers heat from the extract air to the incoming fresh air. Any condensate formed is neatly collected and drained. In summer, the system helps to cool the incoming air. Efficiency: 84% to 92%.
• Powerful EC Fans: Utilizes latest-generation, electronically commutated (EC) motors with an external rotor and backward-curved blades. They boast high performance (up to 90% efficiency) and allow for precise and quiet control of large airflows.
• Effective Filtration: Supply air cleanliness is ensured by G4 and F7 class panel filters. Air extracted from the premises is filtered by a G4 class filter.
• Motorized Bypass (Air Diversion): An integrated automatic air bypass damper allows for efficient ventilation with cool outdoor air in summer, bypassing the heat exchanger, thus saving energy.
• Smart Control with Wi-Fi: A wireless communication automation system is standard, allowing for convenient remote control of the unit via the RECOM AHU mobile application (remote control panel purchased separately).
• Frost Protection with Pressure Switch: An integrated system protects the heat exchanger from freezing, utilizing a pressure switch (in RECOM 6S/SE EC models) and stopping the supply air fan if necessary. A preheater can be connected for additional protection.
