Frequently Asked Questions

1. How do I know which insulation type to select for my package?

Choosing an insulation requires a prioritization between cost and performance. Higher performing insulation will always decrease the amount of refrigerant that is needed to ship your products, but also has a cost that can be disproportional to its benefit. This can be offset by lowered freight charges and reusing the shippers. Normally, the higher-end materials are used for products that have a very high value or are very difficult to replace since the improved performance will also mitigate risk of the temperature going out of range.

2. If phase change materials cost more than traditional gel packs, why would I use them if I’m trying to save on cost?

While it is true that phase change materials do cost more per unit than a traditional gel pack, your overall delivered cost will wind up being less in the long run. Since phase change materials are engineered to hold very specific temperature ranges, your shipment will require less components for the system. Trying to hold that same temperature with conditioned gel packs will require additional components to buffer the temperature. This makes your package weigh significantly more, resulting in much higher shipping charges. If you are shipping valuable products, using PCMs will more accurately hold the required temperature range, decreasing the chances of rejected product.

3. How do I know if I need to test my package?

In order to understand if a package is in need of testing, your company may want to think about the following:

  1. Whether your packaging works the way your brand desires
  2. Whether your package configuration encases the product properly
  3. Whether your product is getting safely from Point A to Point B in its current packaging
  4. Whether you are confident that your product will be compliant with FDA regulations and follow shipping service guidelines

If your company is uncertain about or might be questioning any of the above, Cryopak can help create the resolution. We will provide the best customer service and quality to obtain the best results for your package configuration.

4. When should I use an external sensor instead of the internal temperature sensor?

An external sensor should be used:

  1. When the best response time is required. An external sensor will respond to changes in its environment slightly quicker than an internal sensor.
  2. When the temperature of the environment may not be within the operating temperature limits of the logger.
  3. When the logger cannot be placed within the cargo to be monitored and the temperature within the cargo is what is to be monitored. An external temperature sensor occupies far less space than a logger will.
  4. When the environment to be monitored is in a non-transparent and/or soundproof area and it is required to continuously view the status of the logger, like if the logger is in alarm mode. A logger does not need to be located in the same area as the external temperature sensor.

5. Where is the best location to place the logger and/or the external sensor?

A logger, or external sensor, best functions when placed in a location where abnormal air currents and environmental changes are not an issue. For example, if you want to monitor the temperature of a room, it is advisable not to place the logger too close to the door. Otherwise, every time the door is opened the logger and/or external sensor will be subjected to the temperature of the neighbouring room, while the, average, temperature of the room may not actually significantly change. A real time monitoring system might be a viable alternative if you want to constantly stream data back to a designated location.
