Sanitization: reduces microbial populations to levels considered safe by public health standards (generally 99.9% of bacterium). This is usually accomplished by high moist temperature.

Sterilization: All living cells, viable spores, viruses and viriods are destroyed within a field.

Disinfectant: Chemicals used for the killing, inhibition or removal of microbes that may cause disease. Also reduces microbial population. Nonetheless, these chemicals tend to build up and create chemical resistance to germs.

Autoclave: uses steam at a pressure of 15 pounds of pressure per square inch (psi) which increases the temperature of steam to 121oC. Under these conditions all organisms and their endospores are killed in 20 minutes. Autoclaving is used to sterilize culture media, instruments, dressings and medical equipment.

TDT: Thermal Death Time: Shortest time needed to kill all organisms in a microbial suspension at a specific temperature under defined conditions.

Infectious Disease: is any disease caused by the invasion of pathogenic microorganisms in the body. Infection indicates presence of pathogens in living tissues. An infected person may or may not exhibit signs and symptoms of disease. Contamination means that pathogenic microorganisms are present in or on non living materials such as mattresses, surfaces such as bathrooms, bed rails, food prep areas, public places, and in your own home. Discharges from human or animal sources, or food and water are also candidates of infectious diseases.

Our Cleaning Systems utilize 3 vital cleaning factors:

1• Heat
The most frequently used method of physically controlling microbes is moist heat. Increasing temperatures tends to become microbicidal (cidal = Kills) and decreasing temperatures tends to become micro biostatic ( static = inhibits). Moist heat is the most powerful cleaning assistant for it weakens the bond between dirt and surfaces in addition to killing bacteria, spores and other undesirable microorganisms. The TDT needed to destroy a more resistant endospore is about 200 degrees Fahrenheit. Our equipment operates at very high temperatures and is safely engineered. In fact, for many years now, medical professionals have been sterilizing their medical instruments by using autoclaves - which use superheated steam .

Note: There are two types of heat: Dry and Moist.

MOIST HEAT
• Moist heat kills viruses, bacteria and fungi
• Boiling for 10 minutes enough to destroy vegetative cells but not spores
DRY HEAT
• Absence of water; items placed in oven at 160-170 deg Celsius for 2-3 hours
• Less effective than moist heat

2• Moisture
Water is mans oldest know solvent. Vapor Cleaning Systems utilize dry steam and since superheated dry steam vapor is essentially still water, the gaseous vapor evaporates dirt and other particles from surfaces and destroys them.

3• Pressure
Under high temperature and pressure pure water becomes dry vapor. This is a plus when cleaning because there is little excess water to be wiped up. Less expensive machines will have wetter steam because they have lower temperature and pressure. The ingenious technology of the Vesta Vapor System's vary between 290 and 340 degrees Fahrenheit and with psi (pounds per square inch) of 60 and 122, enabling the steam to be drier.
