Specialist DOFF & TORC Cleaning

DOFF Cleaning

We offer a high temperature, low pressure cleaning system, meaning no saturation of the substrate. With temperatures of up to 150 degrees at the nozzle, we are able to remove moss, algae, fungi and other biological matter.

Our DOFF cleaning system runs a normal water supply through the pump into a hotbox, where a range of temperatures of up to 150º C can be achieved. The low volume of super heated water and steam (5 litres per minute) is then fed through heat resistant hoses to special nozzles where a genuine 150º C is delivered. The surface being cleaned does not suffer any damaging pressure, thermal shock or deep saturation and dries within minutes.

The DOFF system can be used on surfaces such as brick, stone, concrete, tiles, wood, faience and terracotta, and is a useful sterilisation tool for kitchens, toilets, swimming pools, hospitals and factories. The system can be used, not only building restoration, but also in food production, hygiene control, transport and vehicle depots and workshops.

TORC Cleaning

The TORC systems’s most distinctive feature is its revolutionary modulated nozzle, which creates a gentle swirling vortex utilising low volumes of water, fine inert granulate and air. When in the hands of our operators the results that are produced are probably the most sensitive and efficient methods of cleaning masonry. The TORC system creates a gentle swirling vortex using a mixture of low air pressure, little water and a safe inert fine granulate.The Torc Head is modularised into separate components which results in an efficient and gentle swirling vortex using even less water and granulate than the original JOS system.The removable nozzle cone can easily be changed so that a larger cone can be used to clean large areas such as ashlar or a smaller nozzle cone can be used for more intricate detail such as an elaborate capital or rustications.

Previous Work

St Muredach’s Cathedral, Ballina
There was a build up of algae on the sloped surface of the spire, which we were able to clean successfully without saturating the stone surface. 

Donegal Parish Church, Co. Donegal
There was build up of lichen throughout the spire and tower. We were able to clean all elevations successfully without damaging the soft sandstone surface.
