VSR Industrietechnik GmbH

About us

VSR company history
After its founding in 1975, VSR quickly developed into an internationally operating company– partly because our strengths are purposeful advice and problem-solving from the start.
The introduction of the VSR BLASTER® air cannons stood for a completely new technology. In particular, the cement industry quickly recognised the potential of this product, which still sets the standard. The company’s leading position has been maintained through continuous, customer-oriented development. However, we are still able to keep spare part compatibility.
In 1988 we faced a new challenge with the DUSTEX® Dispersion Systems for dedusting: environmental protection. With special nozzle technology and problem-oriented system designs, our systems achieve the highest effectiveness with minimal use of water. Expansion of the product portfolio by water spraying and sprinkling systems and the mobile DUSTEX Fog Blower make it possible to solve nearly all dust problems. The fact that authorities and government agencies today demand qualified water spraying systems and dispersion systems as the standard of technology in accordance with the German Air Pollution and Control Regulation “TA-Luft”, is due to the pioneering work of VSR. Development continues – a research project under the patronage of the Federal Ministry of Education and Research is currently in progress with the aim to also reduce ultra fine dust particles considerably.
Concerning optimisation of bulk material conveyor belt transport, VIBREX® conveyor belt scrapers, LINEX® conveyor belt centralizing idlers and the CAREX® segment block system for chute sealing are important tools that have been developed further and have proven their worth in a variety of applications over the course of time.

The VIBMATIC® vibratory stress reduction procedure takes a special position
as the company’s first product; it is this product that gave it´s name to VSR: Vibration Stress Reduction. In many respects, the process is a true alternative to stress-relief heat treatment: internal tension that would result in unacceptable warping during mechanical processing is simply “vibrated away”. Handling, energy use and logistics can be minimised, thus creating a significant reduction of production costs. Well-known, large corporations have also taken notice of these advantages that are completed by the extensive, environmental protection. In the current 6th generation of equipment, a modern computer controls the vibration generator; this also permits easy creation of logs and treatment reports. In respect to this product too, a research project was recently conducted, subsidized by the Federal Ministry for Economic Affairs and Energy.

VSR BLASTER® Air cannon

VSR BLASTER® Air cannons and air injectors for pneumatic removal of blockages and deposit build-up in silos. Air cannons are fixed to the outside of the silos. They blast the stored compressed air at 4 to 10 bar over a wide cross-section of 50 to 150 mm in diameter in a few milliseconds into the critical interior material zones. Very often, special jet nozzles, such as the isobaric sword nozzle, for example, are used for activating wide areas. The total operating safety and maintainability of well over 25,000 VSR BLASTER® air cannons are put to the test daily. They are also easy to assemble and to control. Air cannons can be components of a cost-effective system of discharge-safe new machines or be effectively adapted to work with existing systems. VSR BLASTER® air cannons are supplied with full assembly and control accessories and can be assembled on request. Areas of application for VSR BLASTER® air cannons: Ratholing and bridging in funnels, silos, bunkers, stockpiles and hoppers with a volume of up to well over 10,000 m³. Similarly, deposits built up in pipelines, heat exchangers and cyclones are removed, even in the high-temperature areas of power stations and cement works with media temperatures of up to well over 1,000 °C. In this area, the VSR changeable nozzle system offers large cost savings through simple jet nozzle exchange. Areas of application for the VSR BLASTER® air injector: Free-blowing of funnels, pipes and filters Shock aerating of bulk goods and soil Air-blowing moulds and tools Cleaning probes and heat exchangers Delivery program: VSR BLASTER® air cannons are available in sizes from 12 to 500 l content and blasting cross-sections of DN 50, DN 100 and DN 150. VSR BLASTER® air injectors are available in sizes of 2, 5 and 8 l content.
