Zehnder - Trusted OEM Exporter and Wholesale Supplier from China

Introducing the latest innovation in indoor air quality from Beijing Holtop Air Conditioning Co., Ltd. - the Zehnder Heat Recovery System. As a leading manufacturer, supplier, and factory in China, we understand the importance of clean and healthy indoor air. That's why we have developed the Zehnder system, designed to provide a constant supply of fresh air while recovering up to 90% of the heat from the stale air being extracted from the building. This energy-efficient system has been engineered to operate silently and is ideal for use in commercial and residential buildings.

The Zehnder system utilizes a highly effective counter-flow heat exchanger to ensure that incoming fresh air is pre-heated, while the stale air being extracted is used to heat the fresh air supply. This innovative approach to heat recovery not only promotes energy savings but also helps to minimize the carbon footprint of buildings. Trust Beijing Holtop Air Conditioning Co., Ltd. to provide you with the best air quality solutions for your indoor environment.
