ZEPHYR Decentralized Heat Recovery Device

Full Description

The BSK Zephyr is a decentralised, single-room heat recovery ventilation (HRV) unit designed to improve indoor air quality while maximising energy efficiency. Ideal for residential and small commercial spaces, the Zephyr operates independently in individual rooms without the need for ductwork, making it perfect for retrofits or areas lacking a central ventilation system.

Utilising a high-performance ceramic heat exchanger and alternating airflow system, it captures and reuses up to 90 % of the thermal energy from outgoing air. This helps maintain a comfortable indoor climate while reducing heating and cooling costs.

With ultra-quiet operation and automatic humidity control, the Zephyr ensures a healthy, silent, and energy-saving indoor environment year-round. Multiple units can be wirelessly linked for coordinated ventilation across larger spaces.

Key Features

• Up to 90% Heat Recovery Efficiency – Captures and reuses heat from outgoing air to reduce energy costs.
• Ceramic Heat Exchanger – Durable and efficient core for long-term thermal performance.
• Silent Multi-Speed Operation – Four ventilation speeds, including ultra-quiet Night Mode for bedrooms.
• Humidity Sensor – Automatically increases ventilation when humidity exceeds set levels.
• Wireless Pairing – Link multiple units for balanced ventilation in larger or multi-room setups.
• Remote Control Included – IR remote for easy operation and setting adjustments.
• No Ductwork Required – Ideal for retrofitting existing buildings or isolated room installations.
• Low Power Consumption – Uses only a few watts of energy during operation.

Detailed Info
