Decentralized (ductless) heat exchange ventilation VENTOsan ZERO

Limited to 10 people, we will present a heat exchange element the same size as the product! Ductless design offers high freedom of design. Performance is described based on test reports according to German DIN standards.

The first type of heat exchange ventilation system, "VentSun 'ZERO'," has a heat exchange rate of 87% (at 70% airflow). It is a ductless heat exchange ventilation system that allows for high design flexibility without the need to run ducts in attics or similar spaces. Unlike typical wall-mounted heat exchange ventilators, it manages the entire living space, making it less likely to create temperature differences between rooms. 【Features】 ◆ Noise level is a maximum of 29 dB! Reduces external noise by up to 56 dB. ◆ Standard equipped with a wind pressure response sensor on the fan. When the wind becomes stronger, the fan speed automatically increases. ◆ All models come standard with a freeze prevention sensor. When the heat exchange element drops below 5°C, it automatically switches to exhaust mode until it rises above 5°C, preventing freezing and condensation accidents within the system. *Currently offering a heat exchange element the same size as the product to the first 10 applicants (with a dryer for experiential use).
