RECOM 2 S2

Product Description

The RECOM S/SE EC series of air handling units are modern, fully assembled ventilation aggregates designed for efficient heat recovery. They ensure quality air filtration, a continuous supply of fresh air to the premises, and removal of stale air. The RECOM 2S2 EC model utilizes a polystyrene counterflow heat exchanger, which efficiently recovers heat from the extract air to the supply air, thereby reducing heating costs. The heat recovery efficiency of this unit reaches up to 93%. Energy-saving EC fans ensure quiet and efficient operation. The unit is designed for use as an energy-efficient solution for ventilating private homes and apartments, compatible with Ø125 mm diameter ducts, and this "2S2" model features 20mm thick casing insulation and an A+ energy efficiency class.

Key Features:

• Casing and Installation: Made of high-quality steel with a polymer coating. Internally lined with a 20 mm thick layer of mineral wool ("2S2/2SE2" modification), providing good heat and sound insulation. Designed for vertical installation.
• Counterflow Heat Exchanger: The RECOM 2S2 EC model is equipped with a polystyrene counterflow heat exchanger. In the cold season, heat from the extract air is transferred to the supply air, thus reducing heat loss due to ventilation. Any condensate formed is collected in a special tray and drained to the sewage system. In the warm season, outdoor air heat is transferred to the extract air, so cooler air enters the premises. Efficiency: 85% to 93%.
• EC Fans: Utilizes high-efficiency electronically commutated (EC) motors with an external rotor and backward-curved blades. Characterized by high performance (up to 90% efficiency) and optimal control across the entire speed range.
• Filtration: Supply air is cleaned by G4 and F7 class panel filters, while extract air is filtered by a G4 class filter.
• Bypass (Air Diversion): Equipped with an air bypass function, allowing for ventilation with cool outdoor air in summer, bypassing the heat exchanger. Motorized bypass damper.
• Smart Automation: Integrated wireless communication automation system. Ability to control the unit via Wi-Fi using the RECOM AHU mobile application (remote control panel purchased separately).
• Frost Protection: The system is protected against freezing by stopping the supply air fan. Provision for connecting a preheater for additional protection is available.
