Industrial and kitchen exhaust ducts especially those in food preparation and 
processing need to be regularly cleaned and degreased to reduce fire hazards 
and pass regulatory requirements.

One of the ways to effectively and safely clean the HVAC system is dry ice 
blasting. The process uses non-abrasive dry ice pellets to clean the insides 
of the duct system. The dry ice sublimates upon impact on surface to lift off 
contaminants such as grease, oil, food residue, bacteria, etc. effectively 
cleaning it.

On top of kitchen exhaust pipeline, dry ice blasting is suited for cleaning 
tools, equipment and machinery in a food processing plant. Dry ice cleaning 
is environmentally friendly because it cleans thoroughly with no use of water 
and chemicals without the need to disassemble or shift any equipment in 
the production line.
