Blast chillers and freezers are used in commercial kitchens and catering companies to quickly cool prepared food items back to their optimal storage temperature. The door gasket ensures that the cabinet is hermetically sealed during this rapid cooling process. For blast chillers and freezers, we recommend door gaskets in -ME- or -MS-quality. These materials remain flexible down to -40 and -20 degrees Celsius respectively. This extends the profile's lifespan when exposed to the extreme temperature fluctuations associated with this equipment.

Types of blast chiller gaskets
For blast chillers and freezers, the material makes all the difference, due to the rapid and extreme temperature fluctuations during the cooling process.
- ME (Extended Life TPE): remains flexible down to -40 degrees Celsius, making it the best choice for blast freezers and intensive use.
- MS (Soft PVC): remains flexible down to -20 degrees Celsius and is suitable for blast chillers and freezers. View our range of push-in profiles in -MS-version.
- Standard PVC: suitable for less intensive use, but less resistant to the rapid temperature fluctuations of a blast chiller.
Replacing a blast chiller gasket? Keep this in mind
With a blast chiller, a reduced seal is noticed more quickly than with regular refrigeration equipment, because the cooling process must take place within a fixed time. When checking, pay attention to:
- Does the profile still respond smoothly or does it feel stiff or brittle after constant temperature shocks?
- Are there hairline cracks in the corners where the most stress is placed on the material?
- Does the door remain fully closed during the cooling process?
Does the cooling process take noticeably longer than normal? Then there is a good chance that the seal is no longer hermetically closed. In addition to a longer cycle time, this also means a higher load on the compressor.
The right profile starts with the right choice
Preferably choose -MS or -ME quality due to its flexibility at low temperatures. Follow our step-by-step plan for taking measurements and determining the required profile. When replacing, always check the old profile code, so that the new profile has the same fit and closure.

Blast chillers and freezers undergo rapid and extreme temperature fluctuations. -ME-material remains flexible down to -40 degrees Celsius and -MS down to -20 degrees Celsius. As a result, these profiles withstand these fluctuations better than standard PVC.
You can, but this material is less resistant to extreme temperature fluctuations. This can cause the profile to harden or crack more quickly, meaning more frequent replacement.
Due to constant temperature fluctuations, a gasket in a blast chiller wears out faster than in regular refrigeration equipment. Moreover, the extreme cold makes the material more susceptible to breakage. An exact replacement period is difficult to give. This depends heavily on the intensity of use. Therefore, check more frequently for signs of wear than with a regular refrigerator or freezer.
No, for both applications we recommend the same qualities: -ME, which remains flexible down to -40 degrees Celsius, or -MS, down to -20 degrees Celsius. This makes them suitable for both rapid chilling to approximately 3 degrees and rapid freezing to approximately -18 degrees.
