How DYNACO high-speed doors for freezer chambers work
Let's look at how DYNACO Freezer high-speed doors work and why they are indispensable for your freezer room.
The primary purpose of DYNACO Freezer doors is to reduce energy consumption. The doors prevent warm, humid air from entering the chamber, reduce cold-air loss and seal the opening as quickly as possible. They help prevent icing problems, significantly reducing freezer chamber operating costs.
Energy-efficiency example
32°C (cold area -20°C; warm warehouse area +12°C) X-axis: opening size from 5 to 16 m². Y-axis: cost of compensating for energy losses while the opening is open. Red: average cost/year with a sliding door. Green: average cost/year with DYNACO
Sealing
The DYNACO door curtain is secured around the perimeter in specially designed flexible guides, eliminating gaps and openings. The doors remove all the disadvantages of common strip curtains.
Heating system
DYNACO doors are equipped with heated guides and motor. This prevents icing and ensures long-lasting operation.
Insulated curtain
For even greater energy efficiency, a special insulated curtain can be installed. It consists of two layers: PVC and thermal-insulation filler. The insulated curtain reduces heat transfer and lowers the risk of ice and condensation formation.
Two door opening heights:
A) for pedestrians or low-profile vehicles; B) for forklifts and reach trucks.
Efficiency in every detail: DYNACO doors have two opening heights, reducing the amount of warm air entering the freezer area and saving energy. Safety comes first!
DYNACO doors provide exceptional operating safety. In addition to standard options such as radars, photocells and others, safety is enhanced by the complete absence of rigid elements in the curtain structure. This protects employees from hazards associated with other types of doors.
Icing problems solved by DYNACO doors.
Slippery floor
When cold air passes through an open doorway, condensation forms. Condensation created on the warm side enters the chamber and freezes, forming ice. Ice is hazardous for moving forklifts. The high operating speed of the doors reduces air exchange, which helps reduce condensation on the floor.
Logistics disruption
Condensation and ice build-up on the door structure slow its operation. As a result, warm air enters the cold room, which can eventually lead to product spoilage.
Equipment damage
Ice and frost on doors and chamber cooling systems damage equipment and reduce operating efficiency.
Ice build-up must be removed
Using slow doors increases moisture in the chamber, forming a thick layer of ice on the ceiling and freezer components. Removing ice is a labour-intensive and lengthy process.
How the automatic 100% curtain self-reinsertion system works in the guides:
After being knocked out (1 and 2), the DYNACO door curtain automatically returns to the guides (3 and 4) during the next opening cycle. No repairs. No production downtime. A solution that saves time and money!
