CONTEC-MODUL SYSTEMAll CONTEC® MODUL Systems are based around a robustly built, welded frame. The units are designed low and compact to guarantee superior blasting capabilities. Two strong attributes of this configuration are the agility of such a powerful machine and the focused energy of the blasting and recovery chambers. CONTEC® shotblasters are fully lined with interchangeable manganese steel linings for the outstanding longevity our customers have grown to expect. The blast and reclaim chamber linings are independent of each other and are designed for simplicity when their replacement is necessary.

• MODUL 200The smallest, yet mighty shotblasting machine in the CONTEC® modular design range. The MODUL 200 has a 7.5 kW motor pushing out a 200 mm blasting width with a very low overall height and weight. Agile, robust and reliable, for daily use on your construction site in small and medium-sized areas.

• MODUL 300, 350 & 500MODUL 300 through to MODUL 500 all utilize a unique 6 bladed BLAST WHEEL thereby guaranteeing a consistent and uniform blast pattern with working widths from 300 to 715 mm, depending on the particular unit and accessories. All units field superb power with motor options varying from 11 to 18.5kw, dependent upon your needs. Excellent results are obtained on concrete, industrial floors, parking decks and underground garages. The MODUL 350 is even available in a tank version for ease of access when blasting steel storage tanks.

• ELGATOR ELGATOR is the most powerful of all CONTEC® blasting systems and achieves fantastic performance on highly compressed and hard industrial floors and of course on steel!Relentless performance and with 2 x 11 or 15 kW motors.

Warehouse floors, ship decks, bridge superstructures or parking garages? We deliver the maximum results with an unprecedented output of 2 x 18.5 kW for the modern contract blasting of large areas!

SHOTBLASTING REVOLUTIONIn 1995 CONTEC® revolutionised the whole of Shotblasting Technology with the introduction of the MODUL SYSTEM. A NEW SHOTBLASTER engineered to be smaller, more agile, user friendly and yet still impact the floor with precision and power when needed. Thus the Extension Unit (EU) was designed to be attached to a SHOTBLASTER MODUL UNIT, which in turn doubles the blasting width, while only using one set of controls. Effective timing of the blastwheels ensures no excessive overlap, while providing a consistent, even blast pattern.

Large jobs or small, we have the blaster to fit your needs. CONTEC Shotblasters are easy and affordable to operate and maintain, making them very formidable machines.

CONTEC Shotblasters excel on steel profiling due to their low-compact design and superior hitting power. Superior production rates are recognized!

SHOTBLASTED

THE SHOTBLASTING PROCESS - EXPLAINED

SHOT (also called abrasive or steel balls) is stored in the SHOT COMPARTMENT (here on the right)

Turn on the DUST EXTRACTION SYSTEM . The BLASTING VALVE must be closed. At the same time as you open the BLASTING VALVE and start releasing SHOT into the BLAST WHEEL, you begin shotblasting the surface area. It’s important to have the shotblaster moving!

Any SHOT/ ABBRASIVE left behind can simply be collected with a MAGNETIC BRUSH, placed in the SHOT COMPARTMENT and used again.

The heart of the Shotblaster is the so-called BLAST WHEEL. CONTEC® uses 4, 5 or 6 bladed blastwheels depending on the size of the machine.

SHOT ABBRASIVE is fed to the center of the BLAST WHEEL via the SHOT CAGE. The SHOT is then blasted onto the surface area by the centrifugal force of the rapidly rotating wheel.

STEP BY STEP

THE SLOWER THE SPEED, THE DEEPER AND ROUGHER OF THE SUBSTRATE!

REMEMBERRemove any foreign debris from the floor to be blasted, such as screws, bolts, stones etc. and if necessary clean the surface beforehand with a broom, CONTEC® MAGNETIC BRUSH or a DUST EXTRACTION SYSTEM.

APPLICATIONS OF MOBILE SHOTBLASTERSCONTEC® mobile shotblasters are widely used for the surface preparation of horizontal and slightly inclined substrates composed of concrete, asphalt, tile, steel and so much more. Steel shot, or grit, is continuously blasted at the surface being prepared. It is separated from the dust or contaminants being removed and recycled for the blasting process. The debris is filtered out of the blasting process with an appropriately sized CONTEC® DUST COLLECTOR, creating virtually a dust free operation. Shotblasting is used to clean and prepare surfaces, remove markings and rubber build up, texture for both aesthetics and slip resistance, remove coatings as well as preparing the substrate for overlays. Shotblasting is also used for the post-treatment of milled floors or diamond-scarified concrete surfaces as a final preparation of the substrate.

THE OPERATIONBlasting is accomplished by repetitive side-by-side lanes or blast paths. The width of the blast path is determined by the size of the shotblaster’s blast opening. It is fully sealed with a magnetic frame, rubber seals and brushes in order to contain the shot. Due to the superior design and engineering, all CONTEC® ELEPAHNT, HORNET, MODUL und ELGATOR, when paired to the appropriately sized CONTEC® Dust Collector provide for a dust-free system to be used indoors, or out.

THE PROCEDUREThe SHOT is literally thrown onto the surface by the high velocity of the centrifugal force of the rapidly rotating BLAST WHEEL. As the SHOT impacts, particles of the surface – debris/dust are removed and rebound together with the SHOT. This dust is then separated from the SHOT using the DUST EXTRACTION SYSTEM and is returned to the SHOT COMPARTMENT, to be fed back into the centrifugal wheel in a continuous circuit.

OPTIMUM RESULTSThe forward operating speed is controlled with the electrical DRIVE UNIT on the larger Shotblasters. The HORNET and certain ELEPHANT models are manually pushed and/or pulled. The resulting substrate will be a clean, open-pored, and profiled surface for which to adhere top coatings, finishes and overlays to, or just to provide a slip resistant finish. In the case of heavily contaminated or coated surfaces, a second blast path is recommended, criss-crossing the first, in order to achieve the desired surface profile.The dust containment bin or bags of the DUST EXTRACTION SYSTEM must be emptied routinely. Proper filter cleaning is accomplished via the pulsed air action, provided by the on-board compressor of the CONTEC ® Dust Collection Systems. Maintaining proper SHOT levels in the machine provides for the best blasting patterns. Any SHOT remaining on the substrate after blasting can picked up with a MAGNETIC BRUSH and reused in the blaster. Edges, corners and joints which cannot be shotblasted can be profiled with the appropriate CONTEC ® grinder.
