H 730/F To save time and energy these top-hat furnaces can also be equipped with mobile hearths. These hearths are moved manually on tracks or if desired electrically. The major advantage is that one bogie can be charged while the other is in the furnace. When changing the bogie the heat remains in the hood so that the retained heat can be used for the next cycle. The furnaces have been used successfully for many years for tempering silica glass tubes and bars.

Extras All models are available with a parallel swivel door for opening when hot. In addition to typical ceramic processes other laboratory processes can also be carried out with this furnace. To reduce the heat-up and cooling times the insulation can also be made of ceramic fibre instead of light refractory bricks. In this case the corner bricks are still laid with mortar in order to locate the heating element

Glass plate test kiln

N 40/14
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.

Gradient furnace

GR 1300/13 Why make things complex and time consuming when a simple and efficient solution is available? This was the principle behind Nabertherms gradient furnace model GR 1300/13. It provides six results in one test. The furnace chamber is 1300 mm long divided into six zones each with a length of 166 mm. Each zone is independently heated and controlled by a seperate thermocouple. For temperature control there is one master controller C 40 and five C 6 slave controllers which follow the program set in the C 40. This control system permits a maximum temperature gradient of 400 C over the total length of the heating chamber. heated length 1300 mm Tmax 1300 C multi-layer high grade insulation heating elements supported on ceramic tubes enabling free heat radiation in the kiln chamber top charging or from the end door separate control of the six heating zones temperature gradient 400 C over the entire length of the heating chamber, each zone can be individually controlled switching and control system built into the bottom section of the kiln turn-key delivery including C 40 controller and five zone controllers C6z

Accessories and extras

To meet the demands customers place on a furnace, we offer numerous useful accessories and extras. By selecting from our wide range of accessories you can optimise a standard furnace to suit your processes: Fan cooling To reduce cooling times and scavenge the kiln chamber with clean air. Either controllable with a simple potentiometer for speed preselection, or linearly using an electronic control system (photo) Multiple zone control to enhance the temperature distribution Removable bogies for pre-loading top-hat furnaces Automatic control of the exhaust air flaps for better ventilation of the kiln chamber and to shorten cycle times (photo) Catalytic afterburning system for organic waste gases Rails and flanged wheels Furnace bogies with flanged wheels running on tracks. Optionally with side transfer facility and parking stations to exchange bogies easily. Bogies can also be electrically powered (photo) Electro-hydraulic lifting door for opening the kiln when hot or for space saving (photo) Further extras on request. Please contact us.

Gas purge systems

For work done under controlled atmospheres we supply gas purging systems. These are basically available for all types and models, customized to suit the respective process conditions. Gas system consisting of pressure reducer (from 10 mbar to 300 mbar) flow meter solenoid valves for low and high gas flows can be regulated by a controller additional timer for setting the pre-purge time for large gas flows automatic/manual selection switch and pilot lights Purge systems available for air nitrogen argon forming gas (95% Nitrogen/5% Hydrogen) Other gases on request.

Regulating technology

Developing adapted furnace control systems is valued highly at Nabertherm. The top priority of every development is to make the furnace easy to use and provide maximum protection of the products, operator and the furnace itself. Depending on the furnace model, we offer a wide range of customized control systems to suit most requirements. The controllers C 30 and C 40 (integrated controller) were especially developed for heat treating glass. Both controllers enable nine customer-specific temperature programs each with 18 segments that may be saved. Heating ramps can be programmed as can hold times and controlled cooling ramps. Through the programmable alarm relay (C 40: 2 alarm relays) additional functions such as the use of cooling fans or an automatic exhaust air flap can be controlled. Both controllers have an RS 422 interface port for controlling and documenting the processes on a computer. An upgradable software MV X.2 is optionally available to simultaneously control up to 16 furnaces from a single PC. The controller P 320 enables complex programs with up to 8 segments to be stored in 9 programs. Depending on the program, additionally an extra function (e.g. exhaust fan or catalyzer) can be activated. A programmable acoustic signal which sounds after the hold time is also standard as is the digital RS 422 interface.
On request we can equip the controllers with a temperature selection limiter to protect the products and the furnace. If the furnace exceeds the set safety temperature this limiter switches off the furnaces heating. Certain heat treatments require a process-orientated control. Many customer problems are solved by using a programmable logic control system (PLC). The PLC not only controls the temperature in the furnace but also reliably monitors all movement and interlocking processes.

Inputs are made through a keyboard or touch panel with a display of the heating curves as a table or graph. Our development engineers also make user-friendliness a top priority for this powerful control system. Of course the package also includes process documentation on the PC.
