Zehnder Charleston Multicolumn Radiator

This EPD applies to the Zehnder Charleston portfolio, which is a multicolumn hydronic radiator to heat a room or building. It generally comes with a custom finish, delivered in a single piece with connections to order. Height, width and length are made to order. The radiator is produced in Lahr, Germany. EPD-Type 1C: average product of 1 plant. The document relates to all life stages from the raw materials, manufacture, transport, installation, operation to disposal of the radiator. The disposal is assumed to be in Germany. Kiwa-Ecobility Experts assumes no liability for manufacturer's information, LCA data and evidence.

The Zehnder Charleston is a multicolumn hydronic radiator to heat a room or building. It generally comes with a custom finish, delivered in a single piece with connections to order. Height, width and length are made to order. The finish in the analysis is white. In this document an average on the bases of two reference models is made. Both models (3060-16 and 2180-8) are among the most sold sizes and are a very good representation of the whole portfolio. The two products below have undergone detailed analysis, and an average assessment based on the two models weighted equally has been conducted for an average kilogram (kg) of radiator. The radiators are produced in Lahr, Germany. EPD type 1C: average product of 1 plant. The processing steps are described below and are illustrated as video here: https://youtu.be/uUhLzT4TmcQ. Step 1: Preparation of raw materials: During the first phase of production of a multicolumn radiator, sheet metal is wound into a coil measuring 1.2 m to 1.5 m in diameter and weighing over 2 t. Steel tubes measuring 5.6 m are cut to the desired length to create the radiator columns. Step 2: Production of the header: The coils of sheet metal are punched by a press to create the two halves of the header. The two pieces are then welded together to form a header. These headers are then sanded and pressure tested with 13 bar before moving onto the next stage. Step 3: Production of the section: The headers and the tubes are now welded together and then ground to make neat joins. At each stage the sections are quality controlled. The sections are hermetically sealed and then immersed in a bath of water. The batch of section is then subjected to a pressure of 15 bar to check for leaks. Step 4: Assembly: The radiator sections are now connected to each other using spot lab welding. Plugs with gaskets are drilled into the radiator according to the specified connection. Further testing checks each radiator for leaks with 15 bar. Step 5: The finishing: Radiators are initially cleaned to remove dust and grease before an electrophoretic dip primer is applied for corrosion protection and a flawless foundation. The radiator then undergoes baking in a furnace at roughly 180 °C to affix the primer to the steel. Upon cooling, the radiator advances along the production line for powder coating. While standard white radiators receive automated painting, other colours and finishes are manually sprayed. The radiator then re-enters the oven, where the powder melts uniformly to provide a shock and heat-resistant finish of superior quality. Step 6: Quality control and packing: Before packing, each radiator is thoroughly quality checked once again and then the radiators are packaged and wrapped using a fully automated system.

The Zehnder Charleston is a multicolumn hydronic radiator to heat a room or building. The made-to-measure range from Zehnder allows to specify the precise dimensions of your radiator, providing a solution for unique spaces. To ensure optimal heat output and an ideal fit the height, width, and depth is adjustable.
