| Use advice for data set | Scope: The declaration and the background LCA report represent DORMA's BTS 80, BTS 80 EMB, and RTS 80 EMB Series concealed door closers. Raw materials and components are provided by suppliers and shipped to DORMA, where the closers are manufactured and assembled at DORMA facilities in Germany. The BTS 80 and RTS 80 differ in how they are mounted to the door (floor versus frame), but are otherwise identical products; the EMB versions include electromagnetic hold-open features. System boundary: Type of EPD: cradle-to-gate - with options. The following modules were considered in this analysis: Product stage: Raw material supply (A1) Inbound transport (A2) Manufacturing (A3)Construction process stage: Distribution (A4) Installation (A5)Use stage: Building operational energy use (B6)End-of-life stage: Disposal (C4)Beyond system boundaries: Reuse, recovery, recycling potential (D) The use stage (B6) is applicable to only the EMB closers. In all other aspects, the models are nearly identical. |
| Technical purpose of product or process | These door closers can control exceptionally heavy single- and double-acting doors (both single and double leaf). They are appropriate for almost any design and can meet most materials, size, and weight requirements. Trouble-free performance under adverse climatic and traffic conditions makes these products dependable and a perfect choice for even the most rigorous applications. The BTS 80 EMB and RTS 80 EMB Series are specifically designed to be used in fire/life safety applications where the hold open is electrically controlled by a fire alarm contact. When installed in conjunction with a maintained control switch, these products can be used as a hold open/privacy function. |

| General comment on data set | DORMA's BTS 80, BTS 80 EMB, and RTS 80 EMB Series of concealed door closers represent the latest in builders hardware technology. The closers can be used in a number of different configurations, including standard, narrow, or wide doors, as well as left-hand and right-hand single- or double-action mounting (both single and double leaf doors, including double leaf doors in combination with a BSR door coordinator). A compact body permits use where larger closers would be prohibitive, and a comprehensive selection of accessories ensures that they can be used successfully with a wide variety of door constructions and floor coverings. These products offer maximum reliability and quality. Benefits include: For the trade: Reduced stock requirements because of separate, interchangeable spindles, and slim product range offering all key functions. For the installer: Suitable for installation with left-hand or right-hand single and double action doors. Interchangeable spindles enable easy adaption to structural conditions—even when retrofitted. For the architect: Concealed installation for maximum visual elegance. All essential functions are provided, and the closers deliver proven, robust design capable of withstanding leaf weights up to 300 kg. For the user: A temperature-independent closing cycle and highly efficient mechanism gives maximum user convenience.The BTS 80 EMB and RTS 80 EMB include a electrohydraulic hold-open function to meet fire protection and other user needs. |

These products offer maximum reliability and quality. Technical data: The concealed door closers employ a cam and roller mechanism, and are capable of controlling interior or exterior doors weighing up to 300 kg. They have a mechanical backcheck at approximately 70°. Dual valve adjustment provides controlled closing speed from approximately 175° opening range, even in cold temperature conditions. Certifications include /ISO 9001/, /ANSI A156.4/ for Grade 1, and /EN 1154/ (CE only for versions without hold-open). Declared unit: The declared unit of this analysis is one concealed door closer. |
