Expand to 2-fan system and 3-fan system
The air tightness testing system for large buildings in the United States typically consists of 2-3 blowers, 2 DG-1000 hosts, and control software. It is mainly used to test the airtightness of large buildings, with a surface area of up to 7000-36000m2 and an internal volume of up to 450000m3. It can be widely used in industrial plants, grain warehouses, fire protection systems, and other large public buildings, and is currently the most airtightness testing equipment.
Three blowers, two DG-1000 hosts, combined with TECLOG software, can form a testing module with a maximum flow range of 27000 m3/h (at 50 Pa). One of the two DG-1000 hosts serves as the main controller, and TECLOG software is used to control the main controller to automatically adjust the fan speed. If the system flow exceeds the range, an additional module can be added, consisting of 6 blowers and 4 hosts for combined testing, which can almost solve all the problems of air tightness testing in large buildings.
