Heritage Stone Cleaning
TORC

The TORC System is a more efficient and improved version of the JOSS system which has been available on the market for over 20 years. It now uses a new gentle vortex swirling action at the nozzle, with low air pressure, little water and very fine granulate. The system has a removable nozzle which can be changed for a larger cone for bigger jobs, or a much smaller cone for more intricate and detailed work.

There is a number of different blast media that can be used with the TORC, which type may depend on the job, some of which are Calcite, Dolomite and Unil.
All the media used approved by Stonehealth and is environmentally friendly, contains less than 1% quartz with no other form of crystalline silica. It is completely safe for the environment & non-toxic.

As the system is extremely low risk to the environment and the material being cleaned, it is one of the recognised methods of cleaning listed buildings, churches, chapels and monuments and is recommended by CADW and English Heritage.

Due to the complexity and the maintenance of the system and must only be used by a fully trained operator. It is an extremely expensive piece of equipment to purchase and is not to mistaken with any ‘hobby’ blast cleaning pots or copies.

All our staff are fully trained to use the Doff system by Stonehealth. We are also among the short list of companies on their rosette scheme who they recommend to carry out work using their systems.


This TORC can be used in conjunction with Paint-Rid, CleanFilm and our DOFF Cleaning System
