How to choose the right medical refrigerators

Medical refrigerators are used in the medical and scientific fields are mostly intended for the conservation and storage of reagents, biological samples, and medication. With the vaccine was widely does all over the world, it is getting more and more common seeing.There are some different features and options available for medical refrigerators. Depending on the different using occasions, Most purpose-built units fall into five categories:

Vaccine Storage
Pharmaceutical Supplies
Blood Bank

Choosing the right medical refrigerator is becoming essential. There are several factors for choosing the right medical refrigerator.

Refrigerator Size

Finding the right size is a vital component in the selection process. If the medical refrigeration unit is too big, it will be difficult to keep the internal temperature within its specified range. Therefore, it is better to look for something that will fit the storage needs. On the other hand, units that are too small for the storage requirements can cause overcrowding and poor internal airflow – which can push some contents towards the back end of the unit, and weaken the effectiveness of the vaccines or other samples inside.

Always be practical with the number of items that will be stored in each medical refrigerator. If possible, try to consider potential changes in storage needs, in order to be prepared.

Refrigerator Placement

It might sound questionable but placement is also a factor to consider, because placement will decide whether the unit is going to be built-in, or free-standing.

For a facility with a small space, it is recommended to use compact units, as they can easily fit in or under most counter-tops; while a big and upright refrigerator is better suited for a workstation that does not need to conserve floor space. Aside from this, it is also critical to ensure that there is a sufficient amount of space surrounding the unit for proper air circulation – about two to four inches on all sides. The unit may also need to be placed in a separate room where it can be kept safe from exposure to varying temperatures during the day.

Temperature Consistency

Another important point that sets a medical refrigerator apart from a home refrigerator is its ability to regulate accurate temperatures. There is +/-1.5°C temp uniformity. Medical refrigeration units are built to ensure that medical samples and supplies are stored within a certain temperature range to maintain viability.  We have the following different temperature range for different categories.

-164°C / -152°C Cryogenic Freezer-86°C Ultra-low Temperature Freezer-40°C Ultra-low Temperature Freezer-10~-25°C Biomedical Freezer2~8°C Pharmacy Refrigerator2~8°C Explosion-proof Refrigerator2~8℃ Ice Lined Refrigerator4±1°C Blood Bank Refrigerator+4℃/+22℃ (±1) Mobile Blood Bank Refrigerator

For example, vaccine fridge usually maintains temperatures between +2°C to +8°C (+35.6°F to +46.4°F).  A change in temperature could affect their potency or ruin research that consumed significant effort and money. Unstable temperature control could also mean loss of blood donations in blood banks and shortages in needed medications for hospitals and medical clinics, while research institutions can opt for refrigerators that can keep samples in tightly specified conditions. Basically, specialized medical refrigeration units can be used for different purposes, as long as their uses are suited for the facility’s needs.

Digital Temperature Monitoring System

Temperature logging is another key component in keeping medical samples and vaccines well-preserved at all times.

The Centers for Disease Control (CDC) suggests buying medical refrigeration units with Temperature Monitoring Devices (TMD) and Digital Data Loggers (DDL) which will allow users to track and gather internal temperature data without opening the door. So that digital temperature monitoring, alarm system, and data storage are the important factors for medical refrigerators.


All medical-grade units require shelving systems that promote efficient airflow. It is advisable to choose medical refrigerators with built-in or easily adjustable shelves to make sure that the unit can hold an ample amount of supply without overcrowding. There should be adequate space between each vaccine vial and biological sample in order for the air to circulate properly.

Our refrigerators are equipped with high-quality shelves made from PVC-coated steel wire with tag cards and classification marks, which are easy to clean.

Security System:

In most facilities, valuable items are likely to be kept inside a medical refrigerator. So it is important to have a unit that comes with a secured lock – a keypad or combination lock. On the other hand, should have a perfect audible & visual alarm system, for example, high and low temperature, sensor error, power failure, low battery, door ajar, mainboard communication error high ambient temperature, samples out of date notification, etc; The compressor start delay and stopping interval protection can ensure reliable operation. Both the touch screen controller and keyboard controller have password protection which can prevent any adjustment of operation without permission.

Additional features to consider of:

Defrost System: A medical refrigeration unit’s defrost system is not something to be ignored.  Manually defrosting a refrigerator will certainly cost time, but it is important for particular applications and requirements. Alternatively, auto-defrosting units require low maintenance and less time but will consume more power than manual units.

Glass Doors and Solid Doors: This will be a matter of priority between security and visibility. Medical refrigerators with glass doors will be helpful, especially in circumstances where the user needs to take a quick look inside without letting any of the cold air out; while solid doors offer extra security. Most of the decisions here will depend on the type of health care facility in which the unit will be used.

Self-Closing Doors:  Self-closing door devices help medical refrigeration units prevent temperatures from being constantly disrupted.

The decision on which medical refrigerator to buy depends primarily on the proposed purpose behind the unit. It is also important to understand that choosing a model is not based solely on the needs of the workplace but also on potential future needs. There is nothing wrong with anticipating future situations. To make the right choice now, consider how all of these factors could come into play over the years the medical refrigerator will be used.
