| Technical purpose of product or process | For supply air systems with demanding acoustic requirements and low airflow velocities. Rectangular VAV terminal units for the supply air control in buildings with variable air volume systems, demanding acoustic requirements and low airflow velocities. For more information see: https://www.trox.de/en/vav-terminal-units/tz-silenzio-27cd2d8bfcbd22d1 Rectangular VAV terminal units for variable and constant air volume systems, for demanding acoustic requirements, suitable for supply air, available in 5 nominal sizes. High control accuracy even in case of unfavourable upstream conditions. Ready-to-commission unit which consists of the mechanical parts and the electronic control components. Each unit contains an averaging effective pressure sensor for volume flow rate measurement, a damper blade, and an integral sound attenuator. Factory-assembled control components complete with wiring and tubing. Effective pressure sensor with 3 mm measuring holes, hence resistant to contamination. Casing with acoustic and thermal insulation. Position of the damper blade indicated externally at shaft extension. The damper blade is factory set to open position, which allows a ventilation airflow even without control; this does not apply to variants with defined safe position NC (normally closed). Meets the hygiene requirements of EN 16798, Part 3, of VDI 6022, Sheet 1, and of DIN 1946, Part 4. This EPD includes the environmental data of the product series TZ-Silenzio. The following represents a representative dataset of the most sold variant in the declared sales year (TZ-Silenzio/125/BM0). |

| General comment on data set | Data quality: Specific data for the product composition are provided by the manufacturer. The data represent the production of the declared product and were collected for EPD development in the year of study. Background data is based on EPDs according to EN 15804 and different LCA databases. The data quality of the raw materials in A1 is presented in the table below. Allocation: The allocation is made in accordance with the provisions of EN 15804. Energy, water and waste production in-house is allocated equally among all products through mass allocation. Effects of primary production of recycled materials is allocated to the main product in which the material was used. The recycling process and transportation of the material is allocated to this analysis. Cut-off criteria: All major raw materials and all the essential energy is included. The production processes for raw materials and energy flows with very small amounts (less than 1%) are not included. These cut-off criteria do not apply for hazardous materials and substances. |
