Elicent Rec Duo 100 Plus RC Heat Recovery

Heat Recovery Ventilation

Traditionally, buildings relied on passive ventilation methods, such as vents and open windows, to introduce fresh air indoors. While these approaches allowed airflow, they offered no control over temperature regulation, often resulting in warm indoor air escaping and being replaced by cold outside air. In such scenarios, the natural response is to increase heating, leading to higher energy consumption and rising utility costs. To address this inefficiency, modern construction practices have shifted toward airtight building designs that minimise air leakage. This evolution demands a new approach to ventilation—one that maintains indoor air quality without sacrificing thermal efficiency. Heat recovery ventilation systems have emerged as the solution, delivering fresh air while extracting excess moisture and pollutants, all without compromising the building’s energy performance.

Why choose the Rec Duo 100 Plus RC?

The REC DUO 100 is an advanced decentralised heat recovery unit (HRU), delivering up to 90% heat recovery efficiency—an ideal solution for enhancing thermal comfort without compromising energy performance. Designed for use in any type of room, it is particularly effective when installed in pairs to ensure balanced airflow and optimise overall system efficiency.

Key Features:

• • Easy installation and maintenance with magnetic coupling/uncoupling of the unit
  • External grill with a net installed from the inside
  • Telescopic duct
  • Remote control operation – handset included
  • Achieve up to 90% Heat Recovery
  • Suitable for walls with a thickness from 300 to 500mm
  • Timer & Humidity sensor
  • Non-ductable
  • Low-maintenance ball-bearing motor
  • Works in pairs with wireless communication between devices

Operating on a “push-pull” principle, the REC DUO 100 utilises a high-performance ceramic heat exchanger. During the extraction (“pull”) cycle, the ceramic core absorbs heat from the outgoing air, which is then transferred to the incoming fresh air during the supply (“push”) cycle.

Designed for continuous operation, the unit runs 24/7 in a low-speed push-pull mode, with speed settings fully adjustable by the end user to suit individual comfort preferences. When increased ventilation is required, a boost mode is automatically activated via the integrated humidistat, which can be set within a range of 45% to 85% relative humidity.

The system intelligently adjusts the airflow rate in response to real-time humidity levels, gradually increasing or decreasing speed as needed. In cases of sustained high humidity, the unit automatically shifts to extraction-only mode to rapidly expel excess moisture. Once the humidity drops below the selected threshold, it seamlessly returns to its standard low-speed push-pull operation. For added convenience and control, the unit comes equipped with a remote controller, enabling easy selection and activation of advanced ventilation functions tailored to enhance indoor comfort.

Disclaimer: The manufacturer specified a sound power level (Lw) of 50 dB(A) for this product, in accordance with ISO 3746:2010. This value quantifies the total acoustic energy emitted. For operational context, a distinct, lower decibel value is also provided, representing the sound pressure level at 3 meters from the source.
