INTRODUCTION
Scope of Manual
This manual provides information for personnel involved in the handling and transport of Envirotainer
container series RAP t2 and is published by Envirotainer AB without warranty.

If there are questions regarding this manual or the container, send an e-mail to
ccm-support@envirotainer.com, or telephone one of our operations centers:

Safety Instructions
The design minimizes hazards to personnel and equipment during use. No material used in the
construction constitutes a risk to the health of the personnel involved. All structural and
mechanical components are free of sharp edges. Every attempt has been made to anticipate
potential dangers and build in protections to prevent injury to personnel.

Normal precautions should be observed when handling locks, doors and lids. Wherever
necessary, warning stickers or texts will be attached to the container as a warning to users and
ground handler personnel.

Always follow the "IATA Dangerous Goods Regulations" when loading the container. For example,
due to low battery level, malfunction, etc., the container may not maintain the temperature in the
container cargo space. Special consideration should be given to this fact if dangerous goods such
as liquids with a low boiling point are to be transported.

The dry ice used as a refrigerant is considered a Class 9 dangerous cargo with the UN
identification number 1845 and is described as “Carbon Dioxide, Solid”.

Do not allow any exposed skin or body part to make physical contact with dry ice. Given the
extreme cold temperature of dry ice (-78.5°C / -109°F), severe frostbite can occur within seconds.
Personnel handling dry ice must use gloves or other insulating material.

Dry ice sublimates into large amounts of CO2 gas. This colorless, odorless gas is heavier than air and
can accumulate and displace oxygen in low areas. Do not enter areas where CO2 may have
accumulated without ventilating the space.

The Container
The RAP t2 container is a temperature controlled air cargo container used to transport
temperature sensitive cargo in the refrigerated, do not freeze (2-25°C / 36-77°F) and deep frozen
product temperature ranges. In general, the product temperature to be maintained must be less
than the ambient temperature.

The container consists of two primary parts; the cargo space and the dry ice bunker (refer to
Figure 1 on the following page). A temperature sensor located in the cargo space monitors the air
temperature, and when cooling is required, two fans are activated. Air from the cargo space is
drawn around the dry ice bunker where it is cooled before re-entering the cargo space.

Dry ice is contained in a separate bunker, which prevents carbon dioxide gas from entering the
cargo space and allows personnel to add dry ice to the container without disturbing the cargo
area.

 INTRODUCTION

The cooling system uses dry ice as a refrigerant and D-cell alkaline batteries to power the control unit
and fan. The container uses two fans for air distribution.

The RAP t2 is a fork liftable LD-9 air cargo container designed to hold four US-pallets 1220 x 1016 mm
(48 x 40") or five EURO-pallets 1200 x 800 mm (47,3 x 31,5") of cargo. The RAP can be moved with
a fork lift only when empty, and must be moved with a roller bed system when it is loaded.

Control Unit
The control unit is the user interface for starting the container, setting the temperature, reading the
actual air temperature inside the cargo space and other information. The control unit also has alert
and alarm indicators. The control unit is located outside the container on the left side (Figure 1).
Refer to section "Control unit operation" for details.

 LIMITS, AMBIENT CONDITIONS

LIMITS, AMBIENT CONDITIONS

The RAP t2 container is designed to maintain the temperature of the cargo shipped in a range
from -20°C (-4°F) to +20°C (+68°F) provided the ambient temperature is 5°C (9°F) to 25°C (45°F)
higher than the set temperature. The following conditions must apply for the container to work
properly:

Pre-conditioning of Cargo
The container does not have battery capacity to cool down or heat up a large quantity of cargo.
The container is designed to maintain the temperature of the cargo. It is therefore very important
that the cargo is pre-conditioned correctly.

Maximum Operating Time without Changing Batteries

The maximum operating time for the container without changing the batteries is 72 hours. If the
container is operated outside the specified temperature limits, the fans may operate continously
which reduces the maximum operating time before batteries must be changed. An example of this
case is deep frozen cargo where it is recommended to change the batteries every 24 hours.

Exposure to Extreme Heat; 25°C (45°F) Above the Set Temperature

Avoid exposure to extreme heat or direct sunshine as it increases the dry ice consumption rate.
Exposure to temperatures 25°C (45°F) above the set temperature should be limited. Take into
account exposure to such conditions when calculating the required amount of dry ice.

Exposure to Temperatures Near or Below the Set Temperature

Since the container does not heat, exposure to temperatures near or below the set temperature
must be avoided. The container must be stored in an environment where temperatures are at least
5°C (9°F) higher than the container set temperature (not applicable to deep frozen cargo).
Exposure to temperatures near or below the set temperatures should be limited.

 PRECONDITIONING

PRECONDITIONING
The cargo and container must be pre-conditioned to the set temperature prior to loading. Improper
precondition will affect the container's ability to maintain cargo temperature.

Cargo Preconditioning
The cargo must be pre-conditioned to the temperature that is to be maintained during transport.

Important!
If pre-conditioning is not carried out correctly, the risk for temperature deviations during shipment
is high.

Cargo temperature recording

If records must be kept of cargo temperature, Envirotainer strongly recommends that temperature
recorders are placed inside cargo boxes in accordance with industrial guidelines. The temperature
displayed on the control unit is the temperature of the air at the sensor in the container and will
fluctuate more than the temperature of the product.

It is also recommended to record ambient temperatures by placing a temperature monitor in the

container document pouch.

Container Preconditioning
Prior to preconditioning, a functional test of the container should be performed. Refer to section
"Control unit operation".

There are three recommended practices for container preconditioning:

Precondition with a temperature-controlled room

1) Turn off the control unit or remove the batteries from the holder.
2) Place the container in a temperature-controlled room that is set to the desired temperature.
3) Open the doors to the cargo space.
4) Allow at least one hour for container preconditioning before loading the cargo.

Precondition with dry ice (for refrigerated cargo)

An amount of dry ice required to pre-condition and maintain the cargo temperature during shipment
(as stated in the Dry Ice Tables) is placed in the dry ice bunker.
1) Calculate the total amount of dry ice required for preconditioning and shipment. Refer to
sections "Dry ice calculation" and "Dry ice tables".
2) Place batteries in the control unit and set the temperature. Refer to section "Control unit
operation".
3) Load the dry ice in the bunker. Refer to section "Cargo/Dry ice loading".
4) Close the doors to the cargo space.
5) Allow at least one hour for container preconditioning before loading the cargo.

 PRECONDITIONING

Precondition with dry ice (for deep frozen cargo)

An amount of dry ice required to pre-condition the container is placed in the dry ice bunker and in
the cargo space to accelerate the preconditioning process.
1) Calculate the total amount of dry ice required for preconditioning and shipment. Refer to
sections "Dry ice calculation" and "Dry ice tables".
2) Place batteries in the control unit and set the temperature. Refer to section "Control unit
operation".
3) Load 20% of total amount of dry ice in the bunker. The remaining dry ice will be loaded with
the cargo. Refer to section "Cargo/Dry ice loading".
4) Distribute 50 kg of dry ice on a pallet in the cargo area.
5) Close the doors to the cargo space.
6) Allow at least one hour for container preconditioning before loading the cargo.

 CARGO / DRY ICE LOADING

CARGO / DRY ICE LOADING

Dry Ice
Dry ice shall be used wrapped or unwrapped as stated in the dry ice tables.

• Wrapped dry ice

Dry ice in paper/plastic bags. Note that the paper/plastic bag shall not be removed when
wrapped dry ice is used. Also note that cardboard boxes should not be put into the dry ice
bunker.
• Unwrapped dry ice
Dry ice without any wrapping.

Avoid using dry ice that has been exposed to ambient conditions for several days before use since
the humidity in the air condensates and freezes on the dry ice blocks, creating a crust of ice and
thereby reducing the effectiveness of the dry ice.

Dry Ice Loading

To load dry ice in the container bunker:
1) Unlatch and open the dry ice bunker lid.
2) Evenly distribute dry ice blocks weighing between 2 kg and 7 kg on the bottom of the bunker.
3) Close and secure the dry ice bunker lid.

Re-Icing the Container

In the event of delays, long transit times or extreme ambient temperatures, it may be necessary
to add dry ice to the container. To "re-ice" the container:
1) Unlatch and open the dry ice bunker lid.
2) Discard any remaining dry ice in the bunker.
3) Put the correct amount of dry ice in the bunker.
Note!
For re-icing of deep frozen shipments it is not allowed to open the container doors without
authorization from the shipper. If allowed to open the container doors by the shipper, place 80
% of the required ice on top of the cargo and 20 % in the bunker. Refer to section "Cargo
loading - Frozen". If not allowed to open the container doors, place all of the ice in the dry ice
bunker.
4) Close and secure the dry ice bunker lid.

 DRY ICE CALCULATION

DRY ICE CALCULATION

Calculate Dry Ice Amount for Container Preconditioning
The dry ice amounts are estimations and for exact amounts, deepening on time of year, please
refer to the online dry ice calculation tool: dryice.envirotainer.com

Only authorized persons should perform dry ice calculations. It is strongly recommended to have
Envirotainer perform the calculation.
To calculate the amount of dry ice needed to precondition the container:
1) Note the container temperature (in Celsius) prior to preconditioning. Although using the actual
container temperature is preferred, an estimate based on the ambient temperature is acceptable.
2) Determine the set temperature (in Celsius) of the product.
3) Subtract "set temperature" from "container temperature" to obtain the "temperature difference".
4) Refer to graph (Figure 17) and locate the "temperature difference" on the horizontal axis.
5) Read up vertically on the graph until reaching the line that corresponds to the container type.
6) Read across to the left to obtain dry ice quantity (in Kilograms) from the vertical axis.
7) This is the amount of dry ice required to precondition the container and should added to the dry
ice necessary to maintain the product temperature, which is obtained from the Dry Ice Tables.

Calculation Example - Dry Ice Preconditioning

An RAP container needs preconditioning with dry ice before loading cargo that has a 5°C
temperature requirement. The current ambient temperature is 25°C.
1) The container temperature is 25°C
2) The set temperature is 5°C
3) Container Temp - Set Temp = 20°C
4) Read up from 20°C to the line and across to the left

 DRY ICE CALCULATION

Calculate Dry Ice Amount for Container Shipment

The dry ice amounts are estimations and for exact amounts, deepening on time of year, please
refer to the online dry ice calculation tool: dryice.envirotainer.com

Only authorized persons should perform dry ice calculations. It is strongly recommended to have
Envirotainer perform the calculation.

To calculate the amount of dry ice needed to maintain temperature during container shipment:
1) Determine the transportation time from container preconditioning to the time the cargo is
unloaded
2) Determine the time for each activity in the transportation schedule
3) Estimate the ambient temperature for each activity by checking the weather forecast
4) Multiply the time and temperature of each activity to determine the product
5) Add the products of all the activities to obtain the product sum
6) Divide the product sum by total hours to determine the average ambient temperature
7) Locate the appropriate dry ice table based on set temperature
Note!
For cargo to be shipped at set temperatures for which no dry ice table is included in this
manual, please contact Envirotainer for advice in dry ice calculation.
8) Locate the corresponding Temperature column & Time row, rounding the values as required
9) Read across & down to determine the dry ice amount in kilograms. Note: 1 kg = 2.2 lbs
Note!
Depending on the size and type (wrapped/unwrapped) of the dry ice blocks it is not always
possible to load the specified amount of dry ice in the dry ice bunker.
10)Use wrapped or unwrapped dry ice as specified in the dry ice table
11)If the required amount of dry ice exceeds the bunker capacity, plan to re-ice the container

Many variables, such as weather conditions, delays and handling, are beyond control. Envirotainer
makes no guarantee that the amount of dry ice indicated in the tables is correct for any specific
shipment. It is recommended that the proper procedures to determine the appropriate amount of dry
ice are implemented.

Version 1.6: Oct. 04, 2011 25 (38)
 DRY ICE CALCULATION

Calculation Example - Container Shipment

To calculate the amount of dry ice needed in a container, imagine that we have RAP container with
a 5°C temperature requirement with the transportation schedule noted below. Also assume dry ice
is used to precondition the container.

Activity Time (Hrs) Temp (°C)

Loading / truck to airport 2 20
Tarmac / aircraft loading 2 25
Flight time 8 15
Aircraft unloading 2 28
Warehouse at destination 11 23

Next, multiply the time and temperature of each activity ("product") and add the products of all the
activities to obtain the product sum. In this example the product sum is 519:

Activity Time (Hrs) Multiply Temp (°C) = Product

Loading / truck to airport 2 X 20 40
Tarmac / aircraft loading 2 X 25 50
Flight time 8 X 15 120
Aircraft unloading 2 X 28 56
Warehouse at destination 11 X 23 253
TOTAL TIME 25 PRODUCT SUM 519

Divide the product sum by total hours to determine the average ambient temperature:

519 / 25 = 20.7°C

From the appropriate dry ice table (excerpt below), locate the corresponding Temperature column
& Time row. In this example, 63 kg of wrapped dry ice is required to maintain the cargo temperature.
Referring to the container preconditioning example, an additional 23 kg is required to precondition
the container, so the total amount of dry ice required is 63 kg + 23 kg = 86 kg.
