RECOM 3S/3SE EPP EC
Product Description
The RECOM 3S/3SE EPP EC L/R (21) is a more powerful, fully featured heat recovery ventilation unit designed for efficient ventilation in medium-sized apartments, townhouses, and small homes. This model retains all the advanced features of the EPP series – an extremely lightweight and airtight EPP (expanded polypropylene) casing, excellent heat and sound insulation properties, and the advanced (21) automation system that allows for integration into Smart Home systems and control via Wi-Fi. Its higher airflow, up to 304 m³/h, ensures fresh air in larger living spaces.
Key Features:
- EPP Casing: The unit's casing is made of expanded polypropylene (EPP), which is lightweight, durable, and possesses high heat and sound-insulating properties. Insulation thickness is 25 mm.
- Mounting: Designed for wall or floor mounting. To ensure comfortable installation and service access, Left (L) and Right (R) hand versions of the unit are available.
- Choice of Heat Exchangers:
- RECOM 3S EPP EC: Equipped with a counter-flow polystyrene heat exchanger, ensuring a high heat recovery efficiency of up to 91%. Seasonal Energy Class A.
- RECOM 3SE EPP EC: Equipped with an enthalpy heat exchanger, which not only recovers heat (up to 84% efficiency) but also transfers moisture, maintaining an optimal indoor microclimate. Seasonal Energy Class A.
- Smart Automation (21 controller): The integrated automation system allows the unit to be integrated into a Smart Home or Building Management System (BMS). Control is available via Wi-Fi using the "Blauberg Home" smartphone app.
- EC Fans: Uses efficient, electronically commutated motors, ensuring quiet, high-performance operation and low energy consumption.
- Filtration: Two built-in Coarse >60% (G4) filters provide efficient air filtration. An optional ePM1 60% (F7) supply filter can be installed.
- Powerful Integrated Pre-heater (E version): An optional version with an integrated 1400 W electric pre-heater is available.
- Bypass: The unit is equipped with a bypass for summer cooling.
