Dry Ice Blasting for Combustible Dust Cleaning

Combustible dust cleaning with dry ice (CO2) removes explosive airborne and surface dust particles from your facility to mitigate the risk of explosion, injuries and workplace safety violations.

Combustible dust is created from a wide variety of common manufacturing materials across many industries including food processing, pharmaceuticals, agricultural products, chemicals, wood and textile products, metal working, and more.

Material dusts that pose a risk of fire and explosion include sugars, flours and starches, grain, tobacco, plastics, wood, paper, pulp, rubber, pharmaceutical components, and other chemicals, dyes, coals, and metals.

Often a by-product of manufacturing processes, combustible dust can accumulate in ceilings, rafters and other hard-to-reach spaces, making cleaning a challenge.

How Dry Ice Blasting Works

Dry ice blasting effectively removes combustible dust without the disadvantages of hydroblasting, including clumping, clogging and the need for water reclamation and disposal.

The process uses CO2 pellets that sublimate on contact, removing dirt, grime, other types of buildup and dust from areas where combustible dust accumulates.

Polar Clean’s compressed air powered, high efficiency particulate air (HEPA) explosion-proof (no moving parts, no electricity, fully grounded) vacuums leave surfaces clean and dry without the introduction of chemicals, debris or outside sources of combustion.
