WHAT IS CO2 CLEANING? CO2
(carbon dioxide), under pressure, creates a hard and extremely cold material
we know as dry ice.
Dry ice is called "dry ice" because there is no liquid. It turns
directly into a gaseous form upon impact,
which is called sublimation.
Mechanical
or physical pressure cleaning methods require both a blast media and a
form of propulsion.
The blast media traditionally consists of grit, sand, oxides, or beads.
The propulsion system is usually pressurized water, pressurized gases,
or mechanically compressed air.
CO2
Pellets (Drice Pellets) are the size of cooking rice and have the unique
properties to strip paint,
remove hydrocarbons, residue and debris but yet will never mar or damage
the surface being blast
cleaned. Brushed metal, aluminum, glass, plastic, ceramics, electrical
wiring, controls, motors, molds,
and insulators can be CO2 blast cleaned with out
any damage to the surface. Another key point, such
as electrical controls, motors, and others can be CO2
Blast cleaned while energized, as CO2 blast
cleaning is non-conductive.
CO2
Drice pellets are extremely cold and maintained in specialized insulated
containers, which maintain
a 2 to 3 day life span. Even though Drice pellets are at -130 degrees,
the objects surface being CO2
blast cleaned will never be lowered less than 10 degrees.
CO2
cleaning is similar to the traditional grit blasting with one major exception;
there is no secondary
waste. The high-density CO2 Drice pellets are accelerated
under compressed air through an air blast
line, striking the area to be cleaned. The pellets are hard yet they explode
on impact removing the
residue material and then returning to a gaseous form. The leftover material
is removed form the
surface and falls to the floor to be either swept or vacuumed.
If the area
to be removed is a hazardous material or is a controlled waste, then there
is a "value-added" feature of CO2 Blast
cleaning. Regulated disposal is critical and expensive. Unlike other conventional
methods of blast cleaning, the only material remaining for disposal is
the removed product itself.
Our mobile
CO2 cleaning systems are mounted on trailers and
are totally self-contained. The system
utilizes a two-man crew, and can normally be set up and operational within
30 minutes. Our systems
are the state-of-the-art and allow us the ability to vary the blast media
from 1# to 6#'s per minute
and control the pressures from 75#'s to 325#'s with an airflow ranging
form 100 cfm to 470 cfm
producing a food quality blast cleaning.
