The mass of dry ice needed for the GreenTherm Dry Ice packaging systems depends on the duration below -20°C required. The tables below summarise, for each size of GreenTherm Dry Ice, a calculated indication of how much dry ice to use for a range of durations and the remaining payload volume in each case.
GreenTherm Dry Ice 7L
An initial mass of 1Kg of Dry Ice should be placed in the base of the system before the payload for all durations.
| Duration (hrs) | Mass of Dry Ice Above Payload (Kg) | Recommended Total Mass of Dry Ice (Kg) | Remaining Payload Volume (L) |
|---|---|---|---|
| 24* | 1.0 | 2.0 | 4.5 |
| 48* | 2.9 | 3.9 | 2.1 |
| 68* | 4.5 | 5.5 | 0.1 |
*Calculated based on a dry ice loss rate of 80.9g/hr (QR: NDP22004-J004-R1).
GreenTherm Dry Ice 14L
An initial mass of 1Kg of Dry Ice should be placed in the base of system before the payload for all durations.
| Duration (hrs) | Mass of Dry Ice Above Payload (Kg) | Recommended Total Mass of Dry Ice (Kg) | Remaining Payload Volume (L) |
|---|---|---|---|
| 48* | 3.9 | 4.9 | 7.8 |
| 72* | 6.4 | 7.4 | 4.7 |
| 103* | 9.5 | 10.5 | 0.8 |
*Calculated based on a dry ice loss rate of 101.9g/hr (QR: NDP22004-J004-R2.1).
GreenTherm Dry Ice 23L
An initial mass of 1.4Kg of Dry Ice should be placed in base of the system before the payload for all durations.
| Duration (hrs) | Mass of Dry Ice Above Payload (Kg) | Recommended Total Mass of Dry Ice (Kg) | Remaining Payload Volume (L) |
|---|---|---|---|
| 48* | 5.1 | 6.5 | 14.8 |
| 72* | 8.3 | 9.7 | 10.8 |
| 104* | 12.6 | 14.0 | 5.5 |
| 120* | 14.8 | 16.2 | 2.7 |
*Calculated based on a dry ice loss rate of 134.4g/hr (QR: NDP22004-J004-R3).
