| Use advice for data set | Scope: This document relates to manufacture, transportation, installation, operation and disposal of volume flow controllers with (VRE, DN 100, comprising the components casing, electrical damper blade, measuring cell and actuator) 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): The required electrical energy for operation of the product with an electric drive motor, and the electrical energy for set point adjustments. 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 100km: multiplication of the eco-balance values by a factor of 2). The end-of-waste status of the motors is reached after treatment or sorting of the contained material fractions. The outlay for treatment has been disregarded in the product life cycle. 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. | ||

| General comment on data set | VRE electronic volume flow controller for constant and variable volume flow rates are maintenance Pipelines and suitable for installation in any position in the pipelines for supply air and exhaust air of ventilation and air conditioning systems. They are adjusted at the factory for the entire volume flow range. The measuring method uses the differential pressure and the damper blade position to measure and control the volume flow. Simultaneously, an efficiency signal on energy-saving optimisation of the system operating pressure is supplied. The measuring principle makes for the high control accuracy of ± 5 % to ± 15 % at all pressures in the volume flow ranges of approx. 1:10. The pipe casing and the centrally supported damper blade are made up of galvanised sheet steel with a stainless steel bearing shaft in special bearing bushes, and the drive housing is made of plastic. The operating modes "constant", "variable" and "4-point", and the overrides "damper blade open" and "damper blade closed" are available. The operating mode "variable" provides the modes 0 - 10 V, 2 - 10 V and 2 - 8 V. Parallel operation and sequential circuits are possible. Constant mechanical VR volume flow controllers are maintenance-free mechanical controllers that operate without an auxiliary power supply to maintain volume flows in ventilation and air conditioning systems constant. They are installed in supply and exhaust air ventilation ducts and are not position-sensitive. The casing and control mechanism are made of galvanized sheet steel. The damper blade which controls the volume flow, is supported centrally and guided with stainless steel bearing shafts in special bearing bushes. The adjustment device is equipped with rotary pointer, dial and locking device. The volume flow setpoints can be set within the volume flow ranges Vmin to Vmax either manually or with a motor. The special control mechanism ensures a high degree of control accuracy with a deviation of only approx. ± 5 % to ± 10 %. Accordingly, the volume flow is kept constant at variable pressures throughout the entire pressure range. Optionally, the VR is available with motorised setting to two volume flow setpoints, or with constant motor setting to any desired volume flow setpoints. 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 in prefabrication with standard production methods. 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 controllers, inspected, packaged and dispatched within the scope of quality assurance as per ISO 9001. Each volume flow controller is adjusted in the factory for high and continuous control accuracy. Operation is subject to an energy management system. Technical data: The requirements as per the harmonised standards for CE markings on electromagentic compatibility (EMC) as per EU Directive 2014/30/EU, the performance rating as per EN 12589 and the associated 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 100 VRE volume flow controller, including actuator and electric control unit. The eco-balance results of variants or varying dimensions of the declared product can be provided by Wildeboer Bauteile GmbH on request. | ||
