Ultrasonic Leak Detectors
At Coltraco Ultrasonics we offer smart ultrasonic safety equipment suitable for testing seals. Our two core products cover testing compartmentation and watertight integrity, our products have been designed to save you cost, time and risk. At Coltrac we welcome you to get in touch to discuss how we can help you improve your seal testing with our Ultrasonic Leak Detectors.
Guided Ultrasonic Leak Detector
Support room Integrity Testing in providing a holistic and thorough integrity test of sealed rooms with a Portascanner® 520 - Ultrasonic Leak Detectors.
How can the Portascanner® 520 assist with Room Integrity/Door Fan Testing?
1. Pre Fan Door Test
The handheld Portascanner® 520 Ultrasonic Leak Detector will assist in:
EARLY ANTICIPATION OF ISSUES: Portascanner® 520 enables fire contractors to indicate location and extent of leak sites in a sealing room prior to a scheduled Door Fan Test
ADD TO RANGE OF SERVICES: Ultrasonic technology can add great value to the Door Fan Test Procedure by finding and patching up leaks before the scheduled test day.
MORE ACCURATE SERVICE QUOTES: Benefiting fire contractors and customers, ultrasound is fast and non-invasive, a quick ultrasonic leak survey can be conducted on site to locate early leak sites.
2. During Integrity Test Fire Suppression
EXACT LEAK LOCATION: Use of ultrasonic technology can pinpoint the exact location while Door Fan Testing is being carried out.
3. Post Compartmentation Survey
REGULATION COMPLIANCE: Once the room has passed Door Fan Testing and is able to achieve the retention time required, periodic room integrity tests can be conducted using an Portascanner® 520 to comply with enclosure integrity maintenance.
NO DISRUPTION: As ultrasound technology is non-invasive, the occupants in the room can remain continuing their daily tasks without affecting the leak detection test results
What is compartmentation and compartmentation survey?
Very briefly, it is related to fire stopping in walls, floors and fire doors, to reduce the spread of fire. Compartmentation often relates to room integrity testing to ensure that a room is sufficiently sealed, to hold in the gaseous fire suppression agent once its been actuated. Extinguishing systems are typically made up of CO2, FM200™ or Novec™1230, and non-liquefied systems are typically Inergen™ or Nitrogen. Leak sites in the room could mean that the compartment may not withhold the fire or gaseous extinguishing agent, which has been specifically designed for the space (called design concentration).
Coltraco Ultrasonics have provided a smart solution which provides quick and easy assurance of compartmentation using ultrasound to detect signal leaking through any apertures within the barriers. Used in part of a room integrity test kit, aiding door fan test equipment, the Portascanner® 520, provides interpretation of the fire resistance of room sealing, labelling them either airtight or giving an indication of the overall leakage of the room. The advantages of being able to accurately detect the exact leak locations through closure integrity testing is self-evident when considered alongside the resistance to collapse and transfer of excessive heat. In a case where there is too much leakage in a room, the Portascanner® 520 Ultrasonic Leak Detector as part of room integrity test equipment is an unrivalled technology for the rapid and accurate identification of these sites so that they can be sealed. 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 Safety Industry.
What are the room integrity testing standards?
Approved document B, Fire Safety, Volume 2, Buildings other than dwelling house states that: 8.0 Every compartment wall should form a complete barrier to fire between the compartments they separate. 8.35 – any stairway or other shaft passing directly from one compartment to another should be enclosed in a protected shaft so as to delay or prevent the spread of fire between compartments
220.127.116.11 At least every 12 months it shall be determined whether boundary penetration or other changes to the protected enclosure have occurred that could affect leakage and extinguishant performance. If this cannot be visually determined, it shall be positively established by repeating the test for enclosure integrity in accordance with Annex E.
18.104.22.168 Where the integrity test reveals increased leakage that would result in an inability to retain the extinguishant for the required period, remedial action shall be carried out
What is the benefit of compartmentation testing?
Emphasised by the BRE is the importance of compartmentation, because if it is not upheld, lives are put at stake, “The fire protection of concealed spaces is of prime importance because any deficiencies in installation and materials are not readily apparent and may quickly be covered over. Any inadequacies in such fire protection cannot be observed by the building users and, unlike other engineering provisions within the building, will not be apparent by its impact on everyday life. Any inadequacies in the fire protection of concealed spaces will only become apparent during the very time that their effectiveness is required – during a fire.” This can also be very important for protecting escape routes.
Integrity Test Examples
Oxygen Reduction System: To ensure an Oxygen Reduction System the system works safely and efficiently is of utmost important for two reasons: (1) A properly sealed room will contain the Nitrogen for a longer period of time, therefore putting less work on the air compressor in order to save energy. (2) If Nitrogen starts to leak from the Server Room, there are safety concerns over where this Nitrogen would leak to as it has the potential to harm occupants in other rooms if the Nitrogen leaks into their room and the oxygen levels were unmonitored.
Testing Enclosures: The Server Room had an area of about 91 metres square. Several areas were tested with the Portascanner® 520 where leakage was probable, and the readings were noted on the drawings. These were the doors, vents, cable penetrations and sections of the wall where gaps were visible.
Results: The Portascanner® 520 Ultrasonic Leak Detector used in the room integrity test, identified the main source of leaks for the room, the doors, where full readings were clearly detected. Multiple air vents in the room were also improperly sealed and some leakage was found into the external room. Cable penetrations leading to the area outside the Server Room were also found to be leaking.
Conclusions: Once the required maintenance was conducted, the room retains its integrity, thus comply and exceed current ISO 14520 regulations.
