HotBox Test Chambers - For determining the stationary heat transfer properties of complex components and finished products used in construction such as doors, windows and bricks
Our HotBox is a constructively complex test apparatus for determining the heat transfer properties of wall elements, walls, windows and doors. In the HotBox, it is possible to simulate real-world conditions as they would exist for a building wall, by simulating conditions both inside the building and on the outside of the wall. To do so, temperature, humidity, air speed and radiation properties on both sides of the test wall must be detectable and precisely adjustable.
In contrast with conventional analysis methods for determining the thermal conductivity (e.g., laser flash, plate method or transient source), the HotBox takes into consideration not only the heat conduction through the test specimen (pure material dependence), but also the heat transfer conditions (material properties and ambient conditions). Thus, for example, the surface structures of walls (e.g., from fluid to solid) or the transmission properties of window panes have a direct influence on the effective heat transfer.
The compact test chamber TDW 4040 was designed for testing brickwork (such as brick, lime sand brick, concrete, or aerated concrete) and basically simulates the temperature and the natural convection inside and outside a building. Optionally, the humidity level in the two sections of the chamber can be set as needed. The HotBox software at the measurement and control units is used to set all parameters, as well as for complete data logging, detailed analysis and printing of test reports.
