Comfort issues can be linked to poor temperature control from inefficient HVAC, these systems can have their efficiencies boosted by improved airtightness. Failure to correctly and effectively seal cable ducts can inflict catastrophic damage to LV-HV electrical distribution networks, substations and power supply. View below our complete ranges of Duct Sealing Products including cable transits to provide a watertight seal and defence against flood damage to low, medium and high voltage cable ducts with additional protection against harmful flammable gas migration and fire spread. All CSD products have beenextensively tested, not only atBeele Engineering technical laboratoriesin the Netherlands, but also by independent experts. Ductwork systems that have a better air tightness, lose less energy than leakier ones. HVAC running costs make up a very substantial part of a building’s operational cost and some of this cost may be recovered by reducing ductwork leakage. It is vital, to make sure the duplex foam is wrapped around each cable, to create separation from each other and the inside of the duct. Running water
Complies with 2011 NEC Articles 225.27, 230.8, 300.5(G), 300.7 (A) onRaceway Seals, and 501.15 (B)(2) The seals can be customised to suit fire rated sealing applications including substation ducts, partitions, walls, floors, and construction systems including MV-HV switch rooms and transformer grids. Once the application is complete and set, Aeroseal sealant is able to withstand 2000Pa of pressure with an estimated lifetime of over 30 years (provided ductwork is not dismantled or cleaned with oxidising chemicals). It can often be very difficult to pinpoint areas of leakage, usually there are many points of small leakage which contribute to a much larger leakage total.
Products
Roxtec offer a complete sealing solution for use across a huge range of industries both on land and at sea. Their modules are inserted around cables or pipes in frames that are attached to a structure by welding, bolting, casting or core drilled holes for a smart, safe and easy solution. CSD Duct Seals provided extensive trials in the York and Aylesbury area using their simple yet effective product, RISE Duct Seal using a split pvc duct frame to create more space in the existing overpopulated cable ducts within the cabinets. Duct sealing system FiloSeal+HD is an engineered universal solution for sealing LV-HV cables and pipes in ducts, boreholes or transit frames. Extremely cost-effective, heavy-duty tape tile is designed to provide a clear visual warning when uncovered FiloSeal+ is very easy to apply regardless of the type of cable scenario in the cable ducts as it uses a uniquely shaped foam piece which positions neatly around the cables or pipes in the duct.
Complies with 2011 NEC Articles 225.27, 230.8, 300.5(G), 300.7 (A) on Raceway Seals, and 501.15 (B)(2) CSD RISE cable duct seals are specified throughout the electric and water utility networks to provide protection of ducts and duct openings against the dangers of water ingress and gas migration with up to 4 hour fire resistance to the spread of flame where cables penetrate fire rated boundaries and building openings – the watertight, gastight and fire resistant seals provide duct protection with accelerated age tests concluding a 50 year level of protection. duct sealing using csd rise seals FiloSeal+HD is an engineered solution that provides a strong support system using the hexagonal tubes which builds up like a honeycomb structure. FiloSeal+HD is suitable for sealing any cable configuration or pipes contained in one duct and also allows easy re-entry of the seal to add or remove cables or pipes as required Duct sealing system FiloSeal+HD is an eginnered universal solution for sealing larger heavy cables and pipes in ducts, boreholes or transit frames.
CSD produced an innovative and cost effective solution to seal our over populated broadband cable ducts. We were impressed with the flexibility of the RISE Duct Seal - the solution will be rolled out by Openreach UK wide." Murray Hayes (In Life Access Engineering Manager - U/G Network. Duct Seals WIMES | The Water Industry Mechanical and Electrical Specifications (WIMES) define the requirements for a wide range of mechanical and electrical equipment used in the UK water industry including cable duct seals. Properties of Cured resin: Fairley dense structure however can be dug out with a blunt tool & Hammer with some degree of difficulty.(Please note there is between 10-15 cm (4-6”) of the expanding resin in each seal depending on the size of duct) The MDII system is suitable in situations where more than one cable or pipe is in the duct. The opening of the duct does not need to be completely round. The revolutionary and patented AEROSEAL process was developed in the 1990s at the University of Berkeley/California. This technology has now been successfully applied in more than 125,000 air duct systems, in residential and commercial buildings, all over the world.
Energy saving calculations can be carried out after application, but it has been possible to reduce fan speeds and is some cases, reduce fan size after Aeroseal, whilst still achieving the required air volumes.
NOFIRNO Duct Seal System
All our duct sealing systems are specified and used by major Electrical, Gas, & Water Utility companies in the UK and Benelux countries. If there is room and the cables are de-energized, a power tool to speed the process up could be used. Once the seal is broken from the cable, there may be a crust of resin still present on the cable; this is due to the excellent adhesion our resin has. The hardest part of removing this seal is the crust that forms when the resin soaks into the foam flange. Safety
