High-tech ventilators improve indoor air quality (video)

Zehnder America Inc. provides high quality heating and ventilation solutions to promote comfortable, healthy, and energy-efficient indoor living in a variety of multifamily and commercial settings.

A division of the Zehnder Group, headquartered in Switzerland, the company recently highlighted some of its non-residential applications at AHR 2016 in Orlando.

The Zehnder air distribution system brings fresh air to all rooms of a building and simultaneously removes extracted, moist or contaminated air and odors. Air is exchanged without drafts or bothersome noises, at the highest possible efficiency, thanks to cross-ventilating. The air volume can be individually adjusted. Fresh air flows through round ducts with smooth internal walls.

Here are some of the key components in the air distribution system:

ComfoTube ventilation pipe

Flexible air distribution pipe, outside ribbed, inside smooth according to DIN EN 60529. The ComfoTube-75 can easily be laid in concrete, directly into the earth or in riser ducts and suspended ceilings. The Zehnder ComfoTube can be easily and quickly installed. Medical grade HDPE provides clean, efficient delivery of air.
