Conclusion on application |
Limitations |
Notes |
| CO2 / EtO |
Applicable |
no |
Blend CO2/EtO can be the substitute for 12/88 but not for all the equipment because it requires higher pressure. |
| HCFC-124 / EtO |
Applicable |
no |
HCFC-124 is the ozone-depleting substance; it can be used in case if there is no other alternative, for example, CO2/EtO blend. |
| [HCFC blend] A / EtO |
Applicable |
no |
Blends with HCFC-124 are ozone-depleting; they can be used in case if there is no other alternative, for example, CO2/EtO blend. |
| Pure ethylene oxide (EtO) |
Applicable |
no |
Ethylene oxide is a toxic carcinogen polluting the atmosphere. Harmful influence can be limited by using catalytic transformation of EtO refuse into carbon dioxide and water or by absorption in acid scrubbers with formation of ethylene glycol. Can be used with account of fire risk measures. |
| Plasma system of hydrogen-peroxide gas |
Applicable |
no |
no |
| Steaming |
Applicable |
no |
Applicable where there are no requirements to heat and moisture. |
