Central Ventilation Unit with Heat Recovery – Comfort and Energy Savings

This heat recovery unit is the heart of an efficient mechanical ventilation system with heat recovery. Designed for ceiling-mounted installation, it ensures a constant supply of fresh air while minimizing heat loss. As a result, your home enjoys a healthy and comfortable microclimate, with reduced heating costs. This is especially important in high-insulation buildings, where traditional ventilation methods can lead to moisture and air quality issues.

Technology for Demanding Users

The enthalpic cross-counterflow heat exchanger (ERV) is the key to the unit’s high efficiency. This design allows for the recovery of not only heat but also moisture from the exhaust air, which is particularly beneficial during winter months—it prevents indoor air from becoming overly dry. Additionally, the unit features an automatic bypass that can fully disable heat recovery when needed—for example, during summer, when you wish to cool the interior. A 1 kW pre-heater provides additional thermal comfort, especially during system startup in low ambient temperatures.

Design and Installation – Simplicity for Professionals

The heat recovery unit has been designed for easy installation and maintenance. Adjustable duct connections and EPDM rubber gaskets ensure airtight seals with ventilation ducts. Vibration-damping elements reduce noise levels, enhancing user comfort. The unit features a double-rotating condensate drain, minimizing moisture-related issues and ensuring long-term reliable operation. Installation is possible in both vertical and horizontal orientations.

• High efficiency: Airflow up to 300 m³/h at 200 Pa ensures effective ventilation even in larger rooms.
• Heat recovery: The enthalpic ERV exchanger recovers up to 95% of heat from exhaust air, significantly reducing heating costs.
• Automation: The automatic bypass adjusts unit operation to current needs, ensuring optimal comfort and energy savings.
• Quiet operation: Low-noise fans and vibration-damping elements minimize sound levels.
• Pre-heater: Additional thermal comfort provided by a 1 kW electric heater.
• Easy maintenance: Unit design allows simple access to components requiring regular servicing.
• Versatility: Support for both vertical and horizontal installation, plus adjustable duct connections, ensures flexible system integration.
