RECOM 4 SE EC

Product Description

The RECOM S/SE EC series of ventilation units are engineered to ensure the highest indoor air quality and energy efficiency, combining advanced technologies with reliable operation. These aggregates not only meticulously filter air but also guarantee a continuous supply of fresh air and effective removal of stale air. The RECOM 4SE EC model stands out with its high-performance enthalpy counterflow heat exchanger, which not only efficiently recovers heat (up to 91% efficiency) but also optimizes indoor humidity levels. This ensures exceptional comfort throughout the year, reducing the need for additional air humidification or dehumidification systems. Modern EC fans operate quietly, efficiently, and economically. The unit is ideally suited for efficient ventilation of medium-sized private homes or apartments and connects to Ø160 mm diameter ducts.

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. Designed for convenient vertical installation.
• Advanced Enthalpy Heat Exchanger: The RECOM 4SE EC model integrates a modern enthalpy counterflow heat exchanger. It not only efficiently recovers heat but also transfers moisture between air streams through a special membrane. This helps maintain a comfortable indoor humidity level, protect against excessive dryness in winter, and reduce air conditioning load in summer. Efficiency: 73% to 91%.
• High-Efficiency 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 airflows.
• Multi-Stage 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: An integrated system protects the heat exchanger from freezing by stopping the supply air fan if necessary. A preheater can be connected for additional protection.
