How to properly maintain your cryogenic freezers

If you work in a laboratory that uses cryogenic freezers, you know how important they are to your work. To keep your freezers working correctly, it is crucial to maintain them regularly. In this blog post, we will give you some tips on how to maintain your cryogenic freezers properly.

1. Check the seals around the doors monthly:

The seals on the doors of cryogenic freezers are essential in keeping the cold air inside and the warm air outside. If the seals are not in good condition, then cold air can escape, and warm air can enter, causing the freezer to work less efficiently.

2. Clean the condenser coils monthly:

The condenser coils on cryogenic freezers must be cleaned regularly to prevent them from getting clogged with dust and dirt. When the coils are clogged, they cannot properly remove heat from the air inside the freezer, causing it to work less efficiently.

3. Clean the evaporator coils yearly:

The evaporator coils on cryogenic freezers also need to be cleaned regularly.

4. Check the door gaskets yearly:

The door gaskets on cryogenic freezers can become worn over time. If the gaskets are not in good condition, then cold air can escape, and warm air can enter, causing the freezer to work less efficiently.

5. Replace the door seal if it is worn:

If the door seal on your cryogenic freezer is worn, it is crucial to replace it. A worn door seal can cause cold air to escape and warm air to enter, causing the freezer to work less efficiently.

6. Inspect the freezer regularly:

It is essential to inspect your cryogenic freezer regularly for any signs of wear or damage. If you notice any problems, it is important to have them fixed as soon as possible.

7. Keep an eye out for ice buildup inside the freezer and clean it out as needed:

Ice buildup inside a cryogenic freezer can cause the freezer to work less efficiently. Therefore, if you notice ice buildup, it is important to clean it out as soon as possible.

8. Schedule a preventative maintenance check with a qualified technician at least once per year:

It is vital to have a qualified technician perform a preventative maintenance check on your cryogenic freezer at least once per year. This will help to ensure that your freezer is working correctly and can help to prevent any future problems.
