RECOM 3 SEF EC

Product Description

The RECOM S/SE EC series of air handling units are designed as advanced and energy-saving ventilation solutions, ensuring the highest level of indoor comfort. These aggregates not only effectively filter air but also ensure a continuous supply of fresh air and removal of stale air. The RECOM 3SE EC model features an enthalpy counterflow heat exchanger, which not only recovers heat with extreme efficiency (up to 90% efficiency) but also maintains an optimal moisture balance indoors. This is particularly important for both winter and summer seasons, increasing comfort and reducing the need for additional humidification or dehumidification systems. High-quality EC fans guarantee quiet, efficient, and economical operation. The unit is adapted 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 30 mm thick layer of mineral wool, ensuring excellent heat and sound insulation. Designed for vertical installation.
• High-Efficiency Enthalpy Heat Exchanger: The RECOM 3SE EC model integrates an advanced enthalpy counterflow heat exchanger. It not only recovers heat but also transfers moisture between air streams through a special membrane. This allows for maintaining a comfortable humidity level indoors and reducing energy consumption. Efficiency: 78% to 90%.
• Next-Generation EC Fans: Utilizes highly efficient, electronically commutated (EC) motors with an external rotor and backward-curved blades. They ensure high efficiency (up to 90%) and allow for precise and quiet control of airflows.
• Quality 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.
• Automatic Bypass (Air Diversion): The unit integrates a motorized air bypass damper, allowing for ventilation with cool outdoor air in summer, bypassing the heat exchanger, thus saving energy.
• Smart Control System: A wireless communication automation system is standard. Convenient control via Wi-Fi using the RECOM AHU mobile application (remote control panel purchased separately).
• Reliable Frost Protection: An integrated protection system against heat exchanger freezing operates by stopping the supply air fan. A preheater can be connected for additional protection.
