REC X series

Product catalog summary
Introduction
The document discusses the PLC's double flow ventilation units, focusing on two series: the X series and the HR series. These units are designed for efficient energy recovery in mechanical ventilation systems.

Specifications
  • X Series: Equipped with crossflow plate heat exchangers, achieving a nominal thermal efficiency of 60%. Suitable for airflows up to 8000 m3/h.
  • HR Series: Features counterflow plate heat exchangers with a nominal thermal efficiency exceeding 90%, eliminating the need for post-heating. Supports airflows up to 6400 m3/h.

Efficiency and Technology
Both series incorporate TAC technology high-efficiency fans to enhance global efficiency. The thermal exchange efficiency varies based on air speed and hydrothermal characteristics, ranging from 50-70% for the X series and 85-93% for the HR series.

Construction and Installation
The REC series is modular, allowing customization based on application requirements. Units are constructed with anodized extruded aluminum profiles and insulated panels. The HR series features 30mm thick panels, while the X series has 15mm panels. Both series can be installed outdoors with appropriate options.

Control System
The R23 control system is used for both series, allowing for independent control of supply airflow and maintaining desired room pressure. It includes features to prevent freezing and supports free-cooling via a servomotor-controlled bypass.

Options and Customization
  • HR Series: Offers various options for air inlets and outlets, including antifreeze dampers and flexible cuffs. Delivered with G4 class filters, with F7 filters for supply air.
  • X Series: Options include post-heating coils, air conditioning sections, and various filtration and connection options.

Selection Program
A selection program is available online to assist in choosing the appropriate REC unit, providing detailed specifications and pricing.

Conclusion
The document emphasizes the ecological and economical benefits of the REC series, highlighting their adaptability and high efficiency in energy recovery.

“REC IS AN INTELLIGENT FOR ONCE, ECONOMICAL Make your choice PLC proposes 2 different series of double flow ventilation units: - the X series is equipped with crossflow plate heat exchangers, with a nominal thermal efficiency of 60%, - the ‘up-market’ HR series, is equipped with counterflow plate heat exchangers, reaching nominal thermal efficiency of more than 90%.This high efficiency is such that no post-heating is necessary. If you mean heat recovery then you must mean efficiency. It is absurd to recover thermal Watts while electrical watts are being wasted. This is the reason why we have...
