Forced Convection Bogie Hearth Furnaces Electrically Heated or Gas-Fired Forced convection bogie hearth furnace W 19150/60AS for tempering of semifinished borosilicate glass products The forced convection bogie hearth furnaces W 1000/60A - W 8300/85A are used when heavy charges weighing up to more than 25 t have to be heat-treated. They are ideal for processes such as solution like glass tempering or cooling from glass, for which a good temperature uniformity is crucial. The high-performance air circulation assures that the temperature uniformity achieved throughout the work space is...

Additional equipment Direct gas heating or upon request with indirect gas heating with radiation tube Electric chain-driven bogie in combination with rail operation for smooth movement of heavy loads up to Model W 4000 Optimization of the temperature uniformity up +/- 3 °C according to DIN 17052-1 see page 71 Bogie running on steel wheels with gear rack drive, no rails in front of the furnace necessary Different possibilities for an extension to a bogie hearth furnace plant: --Additional bogies --Bogie transfer system with parking rails to exchange bogies running on rails or to connect...

Chamber Ovens, Ovens for Laminated Safety Glass (LSG) Electrically Heated or Gas-Fired The chamber ovens of the KTR range can be used for complex drying processes and heat treatment of charges to an application temperature of 260 °C. The high-performance air circulation enables optimum temperature uniformity throughout the work space. A wide range of accessories allow the chamber ovens to be modified to meet specific process requirements. The design for the heat treatment of flammable materials in conformance with EN 1539 (NFPA 86) is available for all sizes. The chamber ovens can also be...

Chamber Ovens, Ovens for Laminated Safety Glass (LSG) Electrically Heated or Gas-Fired Charging cart with pull-out trays KTR 4500 with platform cart, inner lightning and observation windows Accessories Adjustable plate shutters to adapt the air guide to the charge and improve temperature uniformity Guide-in tracks and shelves Shelves with 2/3 extraction with evenly distributed load on the whole shelve surface Platform cart in combination with drive-in tracks Charging cart with rack system in combination with drive-in tracks Sealing shoes for ovens with drive-in tracks to improve temperature...

Clean Room Solutions Clean room applications impose particularly high requirements to the design of the chosen furnace. If the complete furnace is operated in a clean room an essential contamination of the clean room atmosphere must be avoided. Especially, the particle contamination must be reduced to a minimum. The specific application determines the choice of the required furnace technology. In many cases forced convection furnaces are required to achieve the necessary temperature uniformity at lower temperatures. For higher temperatures, Nabertherm has also delivered many furnaces with...

Ovens, also with Safety Technology According to EN 1539 Electrically Heated Oven TR 60 with adjustable fan speed With their maximum working temperature of up to 300 °C and air circulation, the ovens achieve a perfect temperature uniformity which is much better than in ovens of most competitors. They can be used for various applications such as e.g. drying, sterilizing or warm storing. Ample warehousing of standard models provides for short delivery times. Electrical rotating device as additional equipment see page 13 Extricable metal grids to load the oven in different layers Tmax 300 °C...
