High-speed doors for freezer chambers

For 17 years, Dynaco has manufactured industrial energy-saving cold-room doors for low-temperature facilities. Special insulated Dynaco doors have low thermal conductivity and outstanding airtightness. This helps significantly reduce the loss of cold air from a freezer.

Models of automatic roll-up doors for freezer and cold rooms are presented in this catalogue.

Doors for cold stores and freezer chambers

Dynaco specialists developed the special M2 Freezer roll-up door for low-temperature areas (with air temperatures down to -30 degrees).

This model quickly seals the doorway, preventing warm air from entering the cold room. Additional insulation is provided by a seal installed on the crossbeam.

The roll-up door heating system prevents ice forming on the drive mechanism and guides. It allows insulated doors to be installed in cold or freezer rooms. They can also be used together with sliding doors.

Another option, Anti-Frost, automatically clears ice build-up from the curtain.

For chilled warehouses with temperatures from 0 to 5 degrees, the following universal door models are suitable:

• M2 Power;

• M2 All Weather;

• M3 Power;

• M3 All Weather.

Advantages of Dynaco insulated doors:

• 100% curtain self-reinsertion after it leaves the guides. Patented door self-reinsertion technology reduces maintenance costs.

• High operating speed — up to 2.4 m/s. Automatic high-speed overhead doors support the production process and reduce cold-air loss from freezer warehouses.

• Door heating. Heating the working parts of the mechanism prevents both breakdowns and ice formation, saving time and repair costs.

• High duty cycle, reliability and durability (up to 6,000 cycles per day and 3.5 million over the service life).

• Strength. The flexible reinforced PVC curtain is resistant to mechanical damage.



• Complete safety. The curtain is completely safe for staff, vehicles and products because it contains no rigid elements.

• Airtightness and indoor climate control. Dynaco doors provide several times better sealing than conventional overhead doors. The curtain fits tightly against the guides, leaving a gap of less than 1 mm. The sealed curtain reduces energy and freezer maintenance costs and helps preserve stored products.

• Two door opening heights are available for different vehicle dimensions (full opening for trucks and partial opening for pedestrians and low vehicles).

• Easy installation and maintenance.
