Smart ventilation for small spaces – no ducts required
HERU 15 R is a compact room ventilator with energy-efficient heat recovery. Perfect for anyone who wants fresh air and low energy consumption – without complex installation.
Do you have a space without proper ventilation?
Many smaller spaces lack effective ventilation. Installing traditional systems can be expensive, complicated, and sometimes simply impractical.
- Duct systems take up space and require major installation work
- Poor air quality affects health and comfort
- Energy is lost without recovery
- Large systems are often oversized
HERU 15 R is designed to solve exactly this – simply and efficiently.
