| Use advice for data set | Scope: This document refers to the manufacture, transport, installation, operation and disposal of smoke control dampers with electric actuators in systems for smoke extraction, smoke protection, for air supply and in combined systems for the ventilation of buildings. The smoke Control dampers are produced exclusively at the Weener plant in Germany where production data for 2014 was recorded. This document is translated from the German Environmental Product Declaration into English. It is based on the German original version EPD-WIL-20160047-ICC1-DE. The verifier has no influence on the quality of the translation. System boundary: The “cradle to grave” EPD system boundary has a modular design according to /EN 15804:2011/. The LCA for the product under review considers the entire life cycle of the product and therefore all modules: A1-A3 (Product stage): Raw material supply, transport to the manufacturer, production (incl. generation of energy, provision of ancillary materials, packaging material and disposal of waste). A4-A5 (Construction process of a building): Transport to the building site, recycling packaging waste on the building site. Installation in the building is without the use of further resources or the emergence of emissions. B1-B5 (Use stage): No emissions are released when the smoke control damper is used (B1) at product level. The electric energy required for operation in the event of a fire is allocated to Module B6 as it can be regarded in connection with building operation. Maintenance (B2), repair (B3) or replacement of individual components (B4) are not or relevance during the service life under review. During the RSL (Reference Service Life), the smoke control damper does not require any refurbishment according to the manufacturer (B5). All modules within the use stage are therefore either irrelevant or not associated with environmental pollution and thus they are declared with a “0” value in terms of the LCA. B6-B7 (Use stage - building operation): Use of electrical energy for operating the product. C1-C4 (End-of-life stage): De-construction of the product, transport to waste treatment, waste processing, disposal. Analogue to installation, no effects on the environment are to be anticipated during de-construction of the product (C1). Transport to the disposal company (C2) was estimated at 75 km in this study. Waste is separated and sorted. Waste treatment of the various materials contained in the product was considered in Module C3 (with a recycling rate of 95%). Module C4 includes incineration, e.g. of plastic components, in a waste incineration plant. Landfilling of product components (e.g. calcium silicate and collection losses) was also allocated to Module C4. D (Benefits and loads beyond the system boundary): In accordance with the /EN 15804/ standard, all declared benefits and loads from the net flows leaving the product system are allocated to Module D provided they have not reached end-of-waste status. Benefits arise for the electric and thermal energy generated by incinerating materials such as plastic contained in the product. Benefits are also incurred for metal contained in the product. The loads for the associated processing and resmelting processes are allocated to Module D as it can be assumed that metal reaches end-of-waste status directly after the end of the use phase. |
| Technical purpose of product or process | The EK90 smoke control damper (EK92 series) is suitable for smoke protection, smoke extraction systems, air supply and in combined systems for the ventilation of buildings. It can also be used in systems whose smoke control dampers are opened or closed automatically or manually. The “fully open”, “fully closed” and any intermediate positions have been verified and approved. The smoke control damper can be used for installation in rigid walls and ceilings > 100 mm thick, in metal stud walls > 95 mm thick, on and in horizontal or vertical smoke extraction ducts. Smoke extraction ducts with fire-resistance period can be connected on one or both sides of the smoke control damper; the smoke extraction ducts without fire-resistance period can only be connected on one side; the protective grilles can be connected on one or both sides. The installation is wet or dry on site. For more information, please refer to the /manufacturer’s documents/. |

| General comment on data set | The maintenance-free corrosion-resistant EK90 smoke control damper (EK92 series) comprises a casing made of high-temperature resistant, abrasion-resistant calcium silicate with an interior unbreakable damper blade. The smoke control damper features edge protection profiles made of galvanised sheet steel and connecting bore holes. Drive axles are made of stainless steel. Protective grilles, as optional accessories for smoke control dampers without connecting ducts for protecting the flow-through openings, are made of galvanised sheet steel. The operator for opening and closing the smoke control damper is an electric actuator. Special gaskets without additional stops permit large and free cross-sections, extremely low pressure drops and sound power level. The smoke control damper can still be opened even after 25 minutes of full exposure to fire. |

| Technology description including background system | Production is at one location in the Weener plant. The necessary raw and semi-finished parts, ancillary materials and operating materials are delivered by suppliers and are incorporated in production. Semi-finished parts are manufactured in a prefabrication process using standard manufacturing methods. Metal parts are punched and edged to shape, possibly milled; calcium silicate parts are sawn and milled. Blanks are optimised accordingly in order to avoid waste. Any waste incurred is collected and where possible recycled by the corresponding companies, or disposed of and incinerated as domestic waste. Lubricants are largely collected, treated and re-used in production. Dust and fumes are extracted and collected on site. Prefabricated parts are assembled along with bought-in parts to smoke dampers, inspected within the framework of quality assurance to /DIN EN ISO 9001/, packed and shipped. Technical data: The following section includes details on sizes and performance in levels and classes in relation to the essential characteristics of the EN 12101-8. The full declared product performance in terms of all essential characteristics in accordance with EN 12101-8 is provided in the /Declaration of Performance/ issued by Wildeboer Bauteile GmbH. Fire tests were performed in accordance with /DIN EN 1366-10/ and /DIN EN 1366-2/. Declared unit: The Declaration refers to one EK90 smoke control damper (EK92 series) manufactured by Wildeboer Bauteile GmbH measuring 200 mm x 200 mm x 350 mm (unit weight of 32.07 kg) including electric actuator (weighing 1.37 kg) and standard accessory kit (weighing approx. 0.9 kg). Other smoke control dampers with dimensions other than those of the reference smoke control damper reviewed here can be calculated by scaling the results using a weight table provided by Wildeboer Bauteile GmbH, and additional components (e.g. protective grilles, optional accessory kit) can also be added. |
