RECOM 4S/4SE EPP EC

Product Description

RECOM 4S/SE EC EPP L/R is a fully featured air handling unit with heat recovery for air filtration, fresh air supply, and stale air extraction. This model ensures an air flow of up to 410 m³/h. The unit casing is made of expanded polypropylene (EPP), featuring high heat and sound insulation properties. Depending on the modification, the unit has a (21) automation system (A21 controller), allowing the unit to be integrated into Smart Home or Building Management Systems (BMS) and controlled via Wi-Fi

Main Features:

• EPP Casing: Made of expanded polypropylene (EPP), which provides excellent heat and sound insulation. The insulation thickness is 45 mm.
• Mounting: The unit is designed for wall or floor mounting. To ensure comfortable maintenance, left-handed (L) and right-handed (R) models are manufactured.
• Heat Exchanger Options:
  • RECOM 4S EPP: Equipped with a counter-flow polystyrene heat exchanger. Ensures up to 93% heat recovery efficiency (SEC class A+).
  • RECOM 4SE EPP: Equipped with an enthalpy polystyrene heat exchanger. Heat recovery efficiency reaches 83% (SEC class A).
• Smart Automation: Using the (21) controller (A21), the unit can be integrated into BMS or smart home systems. Control is possible via Wi-Fi using a smart app. (14) models are equipped with a wall-mounted control panel featuring LED indication.
• EC Fans: Fans are equipped with efficient electronically commutated (EC) motors.
• Filtration: Two built-in Coarse 90% (G4) filters for efficient air purification. An ePM1 65% (F7) filter can be additionally installed for the supply air.
• Integrated Pre-heater: The (21) modification has an integrated 1050 W electric pre-heater.
• Bypass: Units have a bypass function for summer cooling.
