The company Borrmann Brenner Berlin GmbH was founded in 1949 in Berlin. During the starting years mainly burners for warming up bitumen for small crafts enterprises, in particular the building and roofing trade, were produced.
With the spreading of Liquid gas / Propane as mobile and clean energy source new possibilities within the building industry for the replacement of the up to then usual heating up with coal or combustion of wood resulted.
Business contacts to the Federal Post Office led in the following years to an extension of the production of the product line burner handles for soldering work as well as burners for bitumen digesters to filling joint boxes.
The acquisition of big customers was the defined marketing target. Firm philosophy oriented already very early on innovative products with excellent quality and an intensive customer care. Further customers, like the German Federal Railroads and a number of large companies in the power industry, could also be won by this strategy.
When at the beginning of the seventies the Federal Post Office changed the technology of cable connection, there was no suitable burner set on the market for the handling of the new shrinking hoses.
With one of the Borrmann Brenner Berlin GmbH developed burner novelty this market gap could be closed and the entire Federal Postal Administration equipped.
Since this development also the telecommunications enterprises in Belgium, Switzerland, Austria, Bulgaria, South Africa and a lot of other countries were supplied with these burners. At present the main focus is on the market exploitation in Eastern Europe, in Great Britain and North Africa.
Towards the end of the 70's Borrmann Brenner Berlin GmbH also succeeded in largely filling the market segment of gas burners for road construction machines by actively offering attractive solutions.
In 1994 company headquarters and production were shifted to Baruth / Mark – OT Schöbendorf in Brandenburg, south of Berlin.
Since 1998 the company is certified by DIN-ISO 9001-2000.
The most essential products are:

• Propane tools and burners for cable construction
• Regulating technology and special burners for road building machines
• Burners for other applications and industry

Künneth & Knöchel was founded in Magdeburg in 1887 and has been manufacturing vulcanizing units for worldwide use.
Every unit is manufactured for a specifi c application. We build units for conveyor belts with fabric or steel cord plies up to a belt width of 3,200 mm. The heating platens and pressure bars we use are made of high-quality special aluminium to give many years of reliable service with a high tensile and bending strength. They are selectively available in the forms rectangular shape or rhombic 16.42°, 22° or 30°.
The electrical heating of the heating platens is realised by flat tube heating elements as well as heating foils. The flat tube heating elements are embedded in stainless steel tubing for protection against rust and moisture. Direct contact of the tubes with the heating platens ensures rapid heating. The heating foils are made of silicone with a temperature resistance up to 220°C. The heat flow is evenly distributed everywhere because the heating foil covers the whole surface.
For rapid cooling, our vulcanizing heating platens are available with optional compressed-air or water cooling system. With the water cooling system the heating platens can be cooled down till 80 °C within 10–15 minutes. The electric controller of our vulcanizing units can be operated alternatively by hand or automatically.
We stock a wide range of spare parts to provide a 24-hour service within Germany. All vulcanizing units are thoroughly tested by qualifi ed specialists prior to delivery, including safety and functional tests according to VDE0100 to ensure the highest standard of quality for our products. Only a perfectly functioning vulcanizing unit ensures a perfectly spliced conveyor belt.
We will be happy to provide a quotation without obligation as well as advice on all aspects of our products.
