| Use advice for data set | Scope: This document relates to the manufacture, transportation, installation, operation and disposal of round volume flow limiters (VRL, DN 80) with optional accessories for ventilation and air conditioning systems. The products are produced exclusively in Germany, at the Weener plant, in which the production data for the year 2020 was gathered. System boundary: The system limit of the EPD of the type "cradle to the grave" follows a modular structure as per EN 15804. The eco-balance of the observed products takes into consideration modules A, B, C and D: Product stage (A1-A3) Provision of raw materials and transportation of the raw materials by truck to the factory. Production outlay including packaging material. Treatment of non-metallic production waste. Metallic production waste reaches the end of the waste property directly after generation, and is exported as per module D. Stage of construction of the building structure (A4-A5) Transportation by truck to the construction site (100 km). The transportation distance can be adjusted to building level as necessary (e.g. in case of an actual transportation distance of 200 km: multiplication of the eco-balance values by a factor of 2). Module A5: Packaging treatment. Any resultant credits in module D. Power consumption for installation (any use of manual machines) has not been considered. Stage of use (B1-B5): No emissions are released during use of the product (B1). Servicing (B2) and repair (B3) or replacement of individual components (B4) is not relevant during the observed service life (maintenance-free). According to the manufacturer's information, renovation of the product (B5) is not necessary during the service life. Modules B1 to B5 are therefore declared as "0". Stage of use – Operation of the building (B6-B7): No energy is required for operation of the product. Disposal stage (C1-C4) Manual removal (unencumbered) and transportation by truck to waste processing location (50 km). The transportation distance can be adjusted to building level as necessary (e.g. in case of an actual transportation distance of 100 km: multiplication of the eco-balance values by a factor of 2). Module C3: thermal treatment of raw materials with calorific value. Module C4: Disposal of raw materials without calorific value. Credits and debits outside the system limit (D) Debits and credits from material recycling of metals (including processing) and credits for substituted thermal energy and electricity which has been exported from modules A1-A3, A5 and C3. | ||
| Technical purpose of product or process | Round volume flow limiters are used to control constant volume flow rates in ventilation and air conditioning systems, and replace conventional dampers. As a result, costly and time-consuming manual adjustment of the volumetric flow rates within a ventilation and air conditioning system is no longer necessary. The VRL is suitable for insertion in ventilation ducts. | ||

| General comment on data set | Maintenance-free VRL volume flow limiters are mechanical controllers which operate without an auxiliary power supply in order maintain volume flows in ventilation and air conditioning systems constant. They regulate volume flows independently of pressure with reference to preset setpoint values and keep these constant. They can be used in any installation position in ventilation ducts, for example, in spiral ducts. The setting and control mechanism of the VRL volume flow limiters is enclosed and protected from contamination from the air flow. Furthermore, the lip seals on both sides position and secure the VRL volume flow limiter in the ventilation duct so that a complete enclosure is created. The controller casing and damper blade are made from a special anti-static and microbe-resistant plastic. The smooth surfaces of the air-ducting components virtually eliminate soiling. VRL volume flow limiters thus meet the highest hygienic requirements, see also chapter 7. VRL volume flow limiters are adjusted in the factory in all volume flow ranges, starting with at least 1 : 7. The setpoint can be set continuously variably on site using a rotary pointer on a dial which indicates volume flow and velocity between Vmin and Vmax, and then locked. The special control mechanism generally ensures a high degree of control precision with fluctuation of only ± 5 % to ± 10 % throughout the entire range of application. Refer to the manufacturer's documents for further information. See also chapter 7 for information on hygiene. | ||

| Technology description including background system | Production is performed at a location in the factory in Weener. The necessary raw parts and semi-finished parts, auxiliary parts and consumables are supplied by suppliers and enter into production. The production of semi-finished parts is performed the standard production methods for the material. Metal parts are punched and chamfered or milled into shape. Plastic parts are produced on injection moulding machines. Pre-cut parts are optimised accordingly in order to avoid waste. Waste which is generated nevertheless is collected and recycled as far as possible by appropriate companies, or disposed of as domestic waste and burned. Lubricants are predominantly collected, treated and re-used in production. Dust and vapours are extracted and collected on site. The parts from prefabrication are installed in final assembly together with purchased part to construct the volume flow limiters, inspected, packaged and dispatched within the scope of quality assurance as per ISO 9001. Each volume flow limiter is adjusted in the factory for high and continuous control accuracy. Operation is subject to an energy management system. Technical data: The performance rating as per DIN EN 12589:2002-01, Ventilation for buildings - Air terminal units - Aerodynamic testing and rating of constant and variable rate terminal units is achieved and thus the requirements as per ISO 5135, ISO 3741, ISO 5167-1 and EN 1751 are met. Declared unit: The declaration relates to the manufacture of a single DN 80 volume flow limiter as per PCR:volume flow controllers and volume flow limiters for ventilation systems. The eco-balance results of variants or varying dimensions of the declared product can be provided by Wildeboer Bauteile GmbH on request. | ||
