4 Chamber Ovens and Dryers Heat Soak Test Ovens for Toughened Safety Glass (TSG), Ovens for Laminated Safety Glass (LSG) N 4010/45 HA N 12000/26 HA with individual custom measurements N 560/ N 10000/45 These chamber ovens are available for maximum working temperatures of 260 C or 450 C. They are suitable for numerous processes such as pre-heating of moulds, ageing or drying. The version suitable for temperatures up to 450 C is recommended for Heat Soak testing of Toughened Safety Glass (TSG). During a Heat Soak Test in accordance with EN the panes are exposed to a temperature of 290 C for at least four hours in order to transform nickel sulfide inclusions and hence to prevent the pane from breaking spontaneously later. The documentation of the heat treatment process is strongly recommended. Program entry, visualization and the documentation of the process are achieved by means of the PLC-control in combination with the powerful Nabertherm Control Center (NCC), which registers and archives the temperatures at different measuring points on the pane. The 260 C ovens can also be used for production of Laminated Safety Glass (LSG). During this process two panes are bonded using a laminating foil and entered into the oven inside a vacuum bag. From outside the furnace a vacuum is generated via hose connection in order to avoid air inclusions between the panes during the heat treatment.

23 Combined Furnace System GW 2925/S for Fusing and for Bending/Slumping GW 2925/S GW 2925/S This furnace system is used for both fusing and for bending and slumping. It consists of an unheated table and a heated tub. The top-hat of the furnace is also heated. When the fusing table has been moved under the top-hat, heating is solely realized by means of the heating elements in the top-hat. If the tray has been moved under the top-hat it will be automatically connected and the furnace is heated from all six sides. In order to optimize the temperature uniformity during bending and slumping procedures, the heating will be controlled in three zones.

40 Float-Glass Test Kiln N 40/14 This kiln was designed to test different types of glass plates such as fire protection glass. In addition to the kiln door, there is a second frame which can be swung in front of the inner chamber into which the test plate is placed. This door is fixed with a special mechanism. The kiln chamber is flat and is heated by element coils supported on ceramic tubes mounted only on the back wall so that the heat radiates directly onto the glass surface. The kiln achieves exceptionally short cycle times due to the very small chamber volume and high power input.

42 Process Control and Documentation B 180 P 330 Nabertherm has many years of experience in the design and construction of both standard and custom control system. All controls are remarkable for their ease of use and even in the basic version have a wide variety of functions. Standard Controllers Our extensive line of standard controllers satisfies most customer requirements. Based on the specific furnace model, the controller regulates the furnace temperature reliably. The standard controllers are developed and fabricated within the Nabertherm group. When developing controllers, our focus is on ease of use. From a technical standpoint, these devices are custom-fit for each furnace model or the associated application. From the simple controller with an adjustable temperature to the control unit with freely configurable control parameters, stored programs, PID microprocessor control with self-diagnosis system and a computer interface, we have a solution to meet your requirements.

43 Professional Control and Documentation Alternatives HiProSystems Control and Documentation This professional control system for single and multi-zone furnaces is based on Siemens hardware and can be adapted and upgraded extensively. HiProSystems control is used when more than two process-dependent functions, such as exhaust dampers, cooling fans, automatic movements, etc., have to be handled during a cycle; when furnaces with more than one zone have to be controlled; when special documentation of each batch is required and when remote telediagnostic service is required. The system is also perfectly suited for controlling multiple furnaces or furnace groups. It is flexible and is easily tailored to your process or documentation needs. Alternative User Interfaces Touch panel H 700 This basic panel accommodates most basic needs and is very easy to use. Touch panel H 1700 Firing cycle data and the extra functions activated are clearly displayed in a table. Messages appear as text. Touch panel H 3700 All functions and process data are stored and displayed in easy to read charts. The data can be exported through various interfaces (RS 232, RS 422 /485, USB, Ethernet TCI/IP, MPI, Profibus) to a local PC or your company network for further processing. A CF card also gives the opportunity for data storage and transfer to a PC with a card reader. Extension Package, PC-based for Control, Visualisation and Documentation Nabertherm Control Center NCC Upgrading the HiProSystems-Control individually into an NCC provides for additional interfaces, operating documentation, and service benefits in particular for controlling furnace groups including charge beyond the furnace itself (quenching tank, cooling station etc.): Recommended for heat treatment processes with extensive requirements in respect to documentation e.g. for metals, technical ceramics or in the medicine field Software can be used also in accordance with the AMS 2750 D (NADCAP) Documentation according to the requirements of Food and Drug Administration (FDA), Part 11, EGV 1642/03 possible Charge data can be read in via barcodes Interface for connection to existing Enterprise Database systems (e.g. SAP, Oracle) Connection to mobile phone network for alarm message transmission via SMS Control from various locations over the network Calibration of each measuring point for a specific temperature possible Extendable for calibration of a polygonal line with up to 18 temperatures per measuring point for use at different temperatures e.g for AMS 2750 D applications Controltherm MV Software for Monitoring, Documentation and Control with Standard Controllers Documentation and reproducibility gain increased attention with steadily rising quality standards. The powerful Nabertherm software Controltherm MV provides for an optimum solution for the control and documentation of one or more furnaces as well as charge data.
