Ideal for installation in stores

Fast Dynaco D311LF doors reliably isolate storage areas. They prevent insects, dust, dirt and odours from entering the isolated area, for example the sales floor of a supermarket.

Airtight

High airtightness is achieved through the unique design. The PVC curtain fits securely into the side guides. The lower sealing pocket fits tightly against the floor and compensates for possible floor irregularities and wheel ruts from forklifts. As a result, D311LF roll-up doors are completely airtight around the entire perimeter, with no gaps or play.

Advertising photo printing on the curtain

At retail facilities, the doors can also be used as additional advertising space — the "photo printing on the curtain" option is available based on the customer’s design.

Specifications

Wind load

For the maximum size — up to 450 Pa (wind speed up to 90 km/h). For doors up to W 2,000 x H 3,500 mm — up to 700 Pa (wind speed up to 110 km/h).

Service life

2,000,000 (based on operating experience in the Russian Federation).

Operating principle

Gravity Drive — door curtain without rigid components, with flexible ballast at the bottom of the curtain.

Applications

Compact doors, ideal for retail areas and small openings. Used indoors - retail, warehouse and industrial applications.

Curtain reinsertion unit

If accidentally hit by a vehicle, the curtain normally leaves the guides. The unit is designed to reinsert the door curtain into the guides during the next closing cycle. This occurs automatically or after a close command from any control device.

Motor

IP 65, brakeless, 4-pole, frequency-converter controlled. Power: 0.75 kW.

Limit switches

The door position is continuously monitored by an encoder (digital non-contact absolute position sensor).

Control unit (Compact)

Steel, painted, IP 65. As standard, it includes a frequency converter, magnetic thermal switch, main safety switch, 24 V transformer, programmable closing timer, cycle counter, photocell relay, WDD radio receiver, opening button and emergency stop button. The length of the electrical cables connecting the standard door components allows the control unit to be installed approximately 1,200 mm above the floor and 1,000 mm from the door on the motor side.

Photocells (included as standard)

Detect the presence of a pedestrian or vehicle in the door area. The doors will open and remain open while the object is in this area.

Wireless safety edge (standard equipment)

Dynaco WDD (Patent) consists of a sensing element and radio transmitter installed in the lower seal of the door curtain. The radio receiver is installed in the control unit. A radio signal is transmitted only if the door touches an obstacle while closing. Upon receiving the signal, the control unit immediately opens the door. This operating mode extends lithium-battery life because the transmitter remains inactive most of the time (5 years in standby mode or 100,000 activations). WDD eliminates the need for an unreliable coiled cable or pneumatic sensors.

Power supply

Single-phase 220 V, frequency 50 Hz.
