RECOM 4 SR EC Rotary

Product Description

The RECOM SR EC series of air supply and extract units are advanced, factory-assembled ventilation solutions designed to ensure high indoor air quality and energy efficiency. These aggregates effectively filter incoming fresh air, supply it to the premises, and remove stale air, while the heat from the extract air is recovered to the supply air through an efficient rotary heat exchanger, achieving up to 85% recovery efficiency. Thanks to modern EC motors, energy consumption is significantly lower (1.5–3 times) than with traditional motors, while ensuring quiet operation and high performance. The RECOM 4SR EC model is adapted for vertical installation, connects to Ø160 mm ducts (outlet diameter ØD1: 99mm), and offers the capability for direct connection of a kitchen hood.

Key Features:

• Vertical Installation and Durable Casing: Constructed from galvanized steel with internal 40 mm thick mineral wool insulation, providing excellent heat and sound insulation. The service side (right or left) can be chosen during installation by swapping the front and rear panels.
• Efficient Rotary Heat Exchanger: A dynamically rotating cylinder of aluminum foils not only efficiently recovers heat but also some moisture, thus preventing condensation issues and maintaining a comfortable indoor microclimate. Resistant to frosting. The efficiency for this model ranges from 76% to 85%.
• High-Efficiency EC Motors: Electronically commutated (EC) motors with an external rotor and centrifugal impeller are leaders in energy saving (up to 90% efficiency), allowing for precise and quiet airflow regulation.
• Quality Filtration: Supply air is cleaned in two stages – by G4 and F7 class filters. Air extracted from the premises is filtered by a G4 class filter.
• Integrated Electric Heater: An automatically activating electric heater ensures that the supply air temperature does not fall below the set limit, even if heat recovery is insufficient. Equipped with all necessary safety features.
• Special Connection for Kitchen Hood: All SR series units, including the RECOM 4SR EC, feature a fifth spigot allowing for convenient connection of a kitchen hood extract duct.
• Advanced Control System: Standard Wi-Fi interface allows the unit to be controlled via a mobile application (remote control panel purchased separately). A wide range of functions: speed control, filter status and fault notifications, weekly programming, timer, BOOST, and fireplace modes.
