| Use advice for data set | Scope: This document refers to the manufacture, transport, installation, operation and disposal of circular volume flow limiters with optional accessories for ventilation and air-conditioning systems. The products are produced exclusively at the Weener plant in Germany where production data for 2012 was recorded. System boundary: The “cradle to grave” EPD system boundary has a modular design according to /EN 15804/. The LCA for the product under review considers Modules A, B, C and D: A1-A3 (Product stage): Raw material supply, transport to the manufacturer, production (incl. provision of energy and water, provision of ancillary materials, disposal of waste) A4-A5 (Construction process): Transport to construction site, installation in the building, recycling packaging waste B1-B5 (Use stage): Use of the installed product B6 (Use stage – building operation): Use of electrical energy for the product C1-C4 (End-of-life stage): De-constructing the product, transport to waste treatment, waste processing, disposal D (Credits): Recycling potential |
| Technical purpose of product or process | Circular volume flow limiters serve towards regulating constant volume flows in ventilation and air-conditioning systems, replacing conventional dampers, thereby eliminating the complex manual synchronisation of volume flows within ventilation and air conditioning system. The VRL is suitable for inserting into circular ventilation ducts. |

| General comment on data set | Maintenance-free VRL volume flow limiters are mechanical controllers that operate without auxiliary power supply to maintain constant volume flows in ventilation and air-conditioning systems. They regulate volume flows independently of pressure with reference to preset set points and keep these constant. They can be installed independent of position in circular ventilation ducts, e.g. in spiral ducts. The adjustment and control mechanism in VRL volume flow limiters is enclosed and protected from soiling from the air flow. Furthermore, the lip seals on both sides position and fix the VRL volume flow limiter in the ventilation duct in such a way as to ensure full enclosure. The controller casing and damper blade are made of special antistatic and microbial-resistant plastic. The smooth surfaces of the air-ducting components practically eliminate the possibility of soiling. VRL volume flow limiters therefore comply with maximum hygiene requirements; please refer to section 7 for more information. VRL volume flow limiters are adjusted in the factory to the entire volume flow ranges, min. 1:7. On site, a rotary pointer can be used for setting and locking the infinitely variable set points on a scale with volume flow and velocity specifications between Vmin and Vmax. The special control mechanism generally guarantees a high degree of control accuracy with deviations of only ±5% to ±10% within the entire range of application. More information is available in the /manufacturer’s documents/ and section 7 provides information on hygiene. |

| 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 integrated in production. Semi-finished parts are manufactured using production methods typical for the type of material. Metal parts are punched and edged to shape. Plastic parts are manufactured in injection-moulding machines. 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 volume flow limiters, inspected within the framework of quality assurance to /DIN EN ISO 9001/, packaged and shipped. Each volume flow limiter is factory adjusted to ensure a high and consistent degree of control accuracy. The plant subject to an energy management system. Technical data: The performance rating according to /DIN EN 12589/ and the associated requirements according to /DIN EN ISO 5135/, /DIN EN ISO 3741/, /DIN EN ISO 5167-1/ and /DIN EN 1751/ are fulfilled. Declared unit: This declaration refers to the manufacture of one volume flow limiter according to the /IBU PCR, Part B/. Other volume flow limiters whose dimensions differ from the reference products analysed here can be calculated using a weight chart provided by Wildeboer Bauteile GmbH and scaling the results. |
