After years of utilising ultrasonic technology to identify leak sites in marine applications to test for watertight integrity, Coltraco Ultrasonics realised the potential of harnessing ultrasonics to complement door fan testing with leak detection. The unit allows for easy and simple room integrity testing, which can be completed quickly by one person, without disrupting the building occupants. Clean agents are designed to operate in limited spaces where there is a need for speed of suppression given the asset risk and where the space is occupied by people. They must comply with NFPA 2001 and ISO 14520 standards demanding fast discharge in 10 seconds and fire extinguishing within 30 seconds, delivering confidence to the operator that it delivers “best fire safety practise”. As buildings age or their internal use is changed leak sites develop. It is perfectly positioned to work alongside Door Fan testing in order to meet the total requirements for fire safety regulations and ensure the continuous fire protection of rooms using Clean Agent Fire Suppression systems. As Door Fan Testing has been proven to be a trusted method of room testing by industry experts, it is expected that its dominance shall continue in the near future. The immediate use of the Portascanner™ lies in its improvement of the final stage of room integrity testing – the search for leak sites in the case of a leakage excess – for which it can vastly improve accuracy and operational efficiency
The Portascanner 520 is the most accurate unit of its type, locating a leak site via visual ad audible readings and suppling a definitive numerical results. The unit can test leaks as small as 0.06mm, which is unparalleled accuracy compared to the puffer test technology which is a purely visual inspection. The smoke puffer tests also involves evacuating a building or room whereas the Portascanner™ 520 is completely clean and damage free. The advantages of being able to accurately detect the exact leak locations and size are self-evident when considered alongside the importance of reaching Peak Pressure for clean agent fire suppression to be effective. In a case where there is too much leakage in a room (and thus insufficient Hold Time), the Portascanner™ is an unrivalled ideal for the rapid and accurate identification of these sites so that they can be sealed. It is the first of its kind, intuitive to use, non-invasive, and consequently, is of immediate use to the Fire Industry. The unit also has full Classifcation Society Approval with RINA & ABS.
It is lightweight, fast and easy to use, allowing leak site detection to increase its operational efficiency and speed to a degree that has never been seen thus far in the Fire Industry. This method increases safety, by allowing the user unparalleled leak detection. This leads to the user having superior control of the agent hold time and peak pressure, effectively guaranteeing the identification and extent of leak sites. The unit is also lightweight and hand-held, weighing only 419 grams. The unit can also be used as a pre-surveying inspection tool, prior to bringing in full door fan test equipment.
