Aldes EasyVEC® C4 ULTRA 400: Fire-Rated Centralized Extraction Box

The EasyVEC® C4 ULTRA 400 is a highly efficient and user-friendly centralized extraction box designed for collective residential buildings. It ensures optimal air quality and building preservation while offering significant energy savings.

Product Highlights

Wide range of airflow from 400 to 4,000 m³/h.
Up to 15% reduction in heating consumption compared to standard boxes.
100% recyclable.
Features Aldes patented Micro-watt+ and Auto-Adaptative Technology™ for precise airflow adjustment based on installation needs, leading to substantial heating cost savings.
Remote monitoring capabilities with AldesConnect™™ Pro.

Key Features and Functionality

The EasyVEC® C4 ULTRA 400 is designed for collective residential ventilation, contributing to sufficient air quality and building preservation. When combined with the T.Flow® Hygro+ / Nano domestic hot water production solution, it utilizes naturally present heat from extracted air to warm water.

The integrated Micro-watt+ regulation system automatically creates a custom regulation profile (Auto-Adaptative Technology) to adapt the pressure delivered by the box to the actual installation requirements. This ensures ventilation is provided only when needed, maximizing energy efficiency.

With AldesConnect™™ Pro, users can monitor the ventilation unit remotely, enabling faster response times for troubleshooting and maintenance.

Applications

Suitable for collective residential buildings, new constructions, and renovations.

Installation and Implementation

Installation on an anti-vibration base as per DTU 68.3 recommendations.
Can be installed indoors or outdoors.
Ensure sufficient space in front of the box for easy access to internal components for maintenance.
Preferably install away from wind to minimize pressure loss during air discharge, especially for rooftop installations.
For optimal acoustic and aerodynamic performance, it is recommended to:
- Install silencers at the box connection points.
- Use the ALDES VIRTUO-FIX jointed accessory range.
- Utilize MS PRO flexible airtight sleeves to decouple network vibrations.
