Blower door fan test day for the high-bay warehouse in Singapore 🇸🇬, where our fire prevention system will actively protect chemical products from fire. The air-permeability of the protected area is a key factor for oxygen reduction systems. To achieve the building’s air tightness target, it is essential to perform a preliminary analysis of all the components and construction details, verifying if they are suitable and if they could potentially be improved and provide a detailed assessment report on the airtightness of the area, indicating any problems identified and how to remedy them. In this way the design air-leakages value can be achieved and even improved, which will benefit the overall functioning of the oxygen reduction system.
