Coltraco Ultrasonics are a British high-exporting advanced manufacturer, Headquartered in London. Coltraco Ultrasonics manufacture the Portascanner® AIRTIGHT 520 a micro air leak detector, which aligns with Passive House standards for airtightness, leading the way in airtightness testing quantification, utilizing ultrasonics and computer science:

  • Identifying leak sites with a microscopic level of accuracy, and

  • Measuring and quantifying them using sophisticated algorithms, and

  • Generating a value for the air flow rate through each leak, as well as

  • Calculating the compartment’s overall air permeability.

Energy efficient mechanical ventilation and effective air filtration must start with an airtight building, and controlled airflow within it.

Frequent and regular detection, location and quantification of unwanted air leaks, integrated alongside existing airtightness testing equipment ensures the success of building ventilation strategies, contributing towards Net Zero Strategy.
