Certain industries require certain types of storage facilities, and these facilities may need to be temperature controlled. Traditional freezers may be beneficial for food services and certain manufacturing needs, but temperatures that are even more extreme may be necessary for some instances. Because temperatures range from -346 to -320.44 degrees, liquid nitrogen freezers can provide safe and effective storage for medical samples and even pharmaceutical, industrial, or food manufacturing ingredients and supplies. If you are considering one of these freezers for your facility, here are a few factors to consider.
Accuracy
Accuracy is key when choosing a freezer for your facility. Your freezer should not only be able to store items at the right temperature, but also maintain this temperature for long periods of time.
Considering there will be a great deal of opening and closing of the freezer, air may be lost, affecting the internal temperature. A good-quality freezer will be able to maintain the accurate temperature even when the door is opened.
Without maintaining the proper temperature, you will be putting your samples/supplies at risk. Therefore, accuracy of the temperature can be one of the most important factors to consider when selecting your facility's freezer.
Uniformity
The ability to maintain proper temperatures all through the freezer is also essential. To understand this importance, you should think about the freezer in your home.
Food at the bottom of your refrigerator and freezer will most likely be colder than food stored closer to the top. If you choose an upright liquid nitrogen freezer, this same issue may occur, preventing ALL of your samples and supplies from maintaining a consistent temperature.
Choose a freezer that is designed to keep temperatures uniform. If necessary, measure the temperatures to ensure the upper, lower, and middle portions of the freezer are maintaining a consistent temperature.
Size/Layout
Choosing the right size freezer is important for a few reasons. While you will need sufficient space for your samples, certain sizes may also not be able to fit logically in your work area.
You may be surprised by the different sizes and shapes that are available. You can choose from a standard upright freezer, which looks similar to a residential refrigerator. Or you can invest in a more compact or under-the-counter model that can be built into your workspace. Many people believe upright freezers are best because they utilize more wall/ceiling space than floor space, which can be beneficial if the freezer will be placed in a small lab or clean room.
Remember that interior space is most important since your freezer is designed for storage purposes. If you lack the space for a freezer large enough to accommodate what you need to store, your freezer may need to be installed in a different location.
Specialty freezers are also available. For example, if your liquid nitrogen freezer is used for long-term storage of medical samples of sorts, choose a design that accommodates multiple specimens that can be stored in an organized manner.
Alarm
Finally, you need to choose a freezer that has an alarm system. Even though your freezer is meant to be opened and closed, you never want it to lose its ability to maintain the proper temperature. If an issue occurs, such as a loss of power or human error, that affects the freezer's temperature, an alarm should sound as soon as possible. This will alert you to the potential problem, so it can be solved efficiently before the interior contents are lost.
Choosing your facility's freezer does not have to be a challenging process. This guide and the help of professionals will ensure your liquid nitrogen freezer is designed, installed, and used in the most effective way.
