The preparation of the zones or areas of a refractory wall to be repaired is of the highest importance for the success of a Ceramic Welding repair. If not all damaged material is removed, an early failure of the repair is likely to happen.

1. Pneumatic Hammer
This method has been used to clean Coke Ovens since the earliest days of employing Ceramic Welding more than twenty years ago. This method is still widely used and has a history of success. Beroa NovoCOS offers this technology as part of the total service to our customers.

2. High Speed Cleaning Technology
This new technology offered exclusively by Beroa NovoCOS has a number of advantages in most applications.

• Faster Cleaning Time
• Precise Cleaning of only damaged areas
• Adjustable to both surface area and crack or joint repairs
• Benign to "healthy" brickwork
• No danger of "White finger syndrome"
• Substantially less Ceramic Welding powder consumption
• Ovens are back into production faster than with other methods

These advantages are achieved because the equipment, which is easy to handle, allows very precise work.

HSCT works without vibrations, protecting undamaged refractories and the operator.
