Air Cooled Heat Exchangers are one of the heat exchanger types frequently used in Process, Power, Steel, and several other Industries where a process system generates heat that must be removed, for which there is no local use. When a fire happens, plenum rated cable is designed to: • these cables are constructed with jacket material free from. Surface one side of the spoil board, then glue the surfaced side down to the plenum - I roll the glue on the plenum with a paint roller, put the spoil board on, then turn the vacuum on for half an hour while the glue sets. If you select a QMTM2 certified material to manufacture a plenum-rated cable, you eliminate the need to perform the composition identification step of the finished cable certification process.

Plenum rated cable has a special insulation that has smoke and low flame characteristics. The dielectric constant of foamed PE is lower than solid PE. This strong yet flexible fire-resistant wrap is used to create a fire-resistive enclosure that can reduce flame and smoke spread ratings to acceptable levels in return air plenums. The upper plenum and lower manifold are made from durable A319 aluminum so they’re safe to use with nitrous oxide. Testing indicates that water filled CPVC in diameters 3" or less will pass the 25/50 flame smoke developed requirements for non-metallic material in return air plenums. 3 Material listed and labeled for installation within a plenum. A plenum is an air-distribution box attached directly to the supply outlet of the HVAC equipment that heats or cools the air to make the house comfortable. Once the full plenum was welded in, the plenum was tossed into the jig. Building Code 2018 of Illinois > 26 Plastic > 2604 Interior Finish and Trim > 2604. What we use to calculate Bethel Springs Plenum Installation estimates is average material costs, average hourly labor wages and labor productivity rates. Overview of Air Cooled Heat Exchangers. For instance, most large office buildings. plenum is a compartment or space, such as a duct, actually handling environmental air distribution. Standard PVC is considered a non-plenum insulation option because it does not exhibit the qualities necessary for safe usage in plenum areas. This product is engineered to create a fire-resistive enclosure that can reduce flame and smoke spread ratings to acceptable levels in return air plenums. Due to the moisture resistance of PE it is typically used in a wet environment. What’s the difference between plenum and non plenum?. Materials are tested to UL 1887, NFPA 262 (UL910) and ASTM E84. Depending on whether the ventilation compartment is a duct, plenum, or other defined area, the codes may require materials to be noncombustible or con-structed of specific materials with identified surface burning and smoke characteristics. In terms of plenum fiber cables, the plenum refers to a cable jacket.

During a fire, some of these materials can be toxic and jeopardize the safety of occupants during a fire. Physical Barrier. Ferguson is the #1 US plumbing supply company and a top distributor of HVAC parts, waterworks supplies, and MRO products. While aluminum is the poorest insulation material of the bunch, it's the most durable, is easy to modify, and is the only spacer material allowed by many. For instance, most large office buildings. The reason for this is that if there is a fire in one part of the building then toxic fumes could be fed to the remainder of the building through the ventilation system. Stud wall cavities and the spaces between solid floor joists to be used as air plenums shall comply with the following conditions: 7. Plenum cable is jacketed with a fire-retardant plastic jacket of either a low-smoke polyvinyl chloride (PVC) or a fluorinated ethylene polymer (FEP). Check to see if your EGR Tube from the exhaust manifold will be long enough to properly mate up. What is Plenum cable? • Plenum (CMP) rated cable complies with NFPA-262 and UL-910. By using plenum-rated cable, the levels of toxicity in the smoke would be lower since plenum cable is coated with a jacket that is typically made of flame-resistant material such as Teflon. multi-residential building (with non-ducted air return) is a return air plenum and consequently has to comply with the requirements of the 2014 Florida Building Code, Mechanical, Section "602. The online materials estimator tool is an estimating guide for Unifrax's FyreWrap ® duct and plenum wrap systems. Many HVAC plenums include absorptive wall lining materials such as a standard fibre board or a perforated metal liner backed by fibreglass media to increase the broadband nature of their sound attenuation. In addition, this fiber has a Plenum rating, which will all-around safeguard the application site in case of an emergency and if the cable is installed within air handling spaces since the outer jacket of the cable is coated with low smoke and flame-retardant materials. The requirements for passing the Steiner Tunnel test are outlined in UL standard 1995 (third edition, February 18, 2005).
