20 years since the launch. Performance is described based on test reports from the German DIN standards. With excellent energy-saving ventilation performance, 400,000 units have been sold.
The first type of heat exchange ventilation system, "VentSun Twin," has a heat exchange rate of 94% (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. ★ The "Twin" is equipped with two fans in one unit, which alternately perform intake and exhaust. It is ideal for ventilating independent spaces such as individual rooms and bathrooms (up to 23㎥). ★ The fans come standard with wind pressure response sensors. When the wind increases, the fan speed automatically rises. ★ All models are equipped with freeze prevention sensors as standard. When the heat exchange element drops below 5℃, it automatically switches to exhaust mode until the temperature rises above 5℃, preventing freezing and condensation accidents within the system. ★ Proven high potential and high quality with a simple design, available in Germany for 20 years since its launch. 【Features】 - Standard wind pressure linked fans - Standard freeze prevention function - Inner cover that can open and close in all directions, 360 degrees - Certification obtained from a third-party organization (German Institute for Building Technology)

Company information
Edifice's main products are ventilation systems from Germany's inVENTer and Sweden's Volution Sweden AB. These two companies are part of the Volution Group, which supplies ventilation products to the UK, Europe, and Australasia (Australia, New Zealand, and other parts of Asia). This message was sent to Japan from Germany's inVENTer when the company was founded. Our company has been developing decentralized (ductless) heat exchange ventilation in Germany for over 20 years. We envision a future where our customers can breathe fresh air healthily in ultra-high airtight homes without worrying about ventilation, save energy, and live comfortably. "Simply there, that is air. We are proud to share the simple and innovative indoor environment of 'VentSaan' with many customers." Annett Witting, Chief Operating Officer of inVENTer The reason a small Japanese company came to sell products from leading European companies is due to the representative's track record in engaging in businesses that contribute to the environment. We will leverage that experience to provide helpful services.
