TDW 4140 / 4240

Test chamber to determine the stationary heat transfer properties with a controlled hotbox according to DIN EN ISO 8990, DIN EN 1946-4, DIN EN ISO 12567, DIN EN 12412-2, and ASTM C-1363

TDW_4240

The compact test chambers TDW 4140 and TDW 4240 were designed for testing elements and components used for construction, such as windows, profiles, doors and domes. They basically simulate the temperature and the natural convection inside and outside a building.  Optionally the humidity level in both sections of the chamber can be set as needed. The setting of all parameters, complete data logging, detailed analysis and printing of test reports is performed via the software HotBox 2016 at the measurement and control unit. Additionally available devices, accessories and materials enable the sample preparation and conditioning to optimize the testing procedure.

Features:

  • Insulated warm and cold section with heat exchangers and air deflectors, radial fans, roll chassis on guiding rails and 12-point locking system
  • Hotbox with axial fan, air deflectors, roll chassis and hydraulic cylinders
  • Insulated test frame with roll chassis and openings for sample insertion via forklift
  • Recirculation cooler with water cooling for temperature control of warm and cold section
  • 2 isothermal blocks with 60 measuring points each, 1 set thermocouples, flow sensors
  • Panel with 19“ measuring and control modules, PC, printer and 23“ monitor
  • Interfaces: 2x RS232, 5x USB, 1x Gigabit Ethernet
  • Single license for software HotBox 2016
  • 1 test mask per specimen
  • 1 set calibration panels per specimen with factory calibration certificate
  • 1 set stainless steel guide rails for warm and cold section
