| Technical purpose of product or process | For dual duct systems. VAV dual duct terminal units for dual duct systems with variable volume flows in buildings with demanding acoustic requirements. For more information see: https://www.trox.de/en/vav-terminal-units/tvm-cabf03cfe0a0c086 Rectangular VAV dual duct terminal units for dual duct systems with variable and constant volume flows, available in 6 nominal sizes. Connecting spigots for warm and cold air arranged at an angle of 90°. Up to nominal size 200, an angle of 60° is also possible and is therefore ideal for the refurbishment of older systems with dual duct units. High control accuracy (even with upstream bend R = 1D). Ready-to-commission unit which consists of the mechanical parts and the electronic control components. Each unit contains two averaging effective pressure sensors for volume flow rate measurement, one in the cold air flow and one in the total air flow, two damper blades, and an integral sound attenuator. Factory-mounted control components complete with wiring and tubing. Effective pressure sensor with 3 mm measuring holes, hence resistant to contamination. Spigot on the fan end with groove for double lip seal, suitable for ducts according to EN 1506 or EN 13180. Room end suitable for the connection of flanges. Two baffle plates, one fitted after each damper blade for optimum acoustic and aerodynamic performance. Casing with acoustic and thermal insulation. Position of the damper blade can be seen from the outside at the shaft extension. Closed blade air leakage to EN 1751, class 4 (nominal sizes 125 and 160, class 3). Casing leakage according to EN 1751, class B. Meets the hygiene requirements of VDI 6022, EN 16798, Part 3, VDI 3803 as well as DIN 1946 Part 4. This EPD includes the environmental data of the product series TVM. The following represents a representative dataset of the most sold variant in the declared sales year (TVM/160/BC0). |

| 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. |
