Respect the cold chain and reduce icing

DYNACO flexible high speed freezer doors help to meet important cold storage requirements: stable cold temperatures, minimal energy consumption, respect for the cold chain and the prevention of icing.

The exceptional seal and fast cycle of our  high speed freezer doors keep cold and dry air in and hot and moist air out of your freezer room. The loss of conditioned air is limited and less energy is used.

Minimize temperature variations

Minimal temperature variations limit icing in your freezer room. An optional insulating curtain on the warm side reduces condensation and icing. This means less need for ice and frost removal, no danger of slipping and no damages to your refrigeration devices.

In order to prevent accumulation of ice in the side guides, our cold storage high speed roll up doors are equipped with  low consumption electric heating cables in the side posts.
