DynamicRoll® Frigo 2


Frigo2 Freezer high-speed soft bottom edge doors are fast, self-repairing, easy to clean, and completely safe.

At the heart of the Frigo2 is our innovative double curtain low energy cost design. When closed the two curtains create a dead air space which is then treated with a small amount of heated air. This allows the curtains to remain frost free at the lowest energy expense. It also allows it to be either warm side or cold side mounted.

If the door curtains come out of their guides (for example, in the event of impact with a forklift) the system will automatically reset the curtain back into the guide on the next open cycle.


Door Features:

  • Up to 100″ per second
  • Self-repairing
  • Soft bottom edge
  • Inverter and Encoder standard
  • Oil-free guides allow doors to withstand wind loads
  • Minimal maintenance
  • Quiet operation
  • Wireless safety edge or unroll sensor
  • Photo eyes mounted inside side columns


Supply where indicated on plans. Jamison HPD Model Frigo 2 high speed self-repairing fabric roll up door for temperatures down to -20F but with no more than a 70F temperature difference across the door.

High warm side humidity may cause condensation or may require a lower temperature difference between the cold and warm sides.

Door can be either warm side or cold side mount.

Roll up door side frames and header to be standard galvanized steel.

Frigo 2 has two curtains that roll simultaneously creating a controlled air space when closed that is then treated to minimize condensation.

Standard UL approved control panel to be a painted steel enclosure with window allowing vision of internal LED readout. Control panel uses a proprietary circuit board with inverter.

Standard opening speed is up to 100” per second based on size. Standard closing speed is 32″ per second. Circuit board has LED lighted display showing operation modes and information codes.

Door curtains are made of reinforced PVC, with flexible weighted soft bottom edge. The edge of curtain has continuous injection molded teeth that then move up and down in a self-lubricating polyethylene track attached to structural galvanized side frames.

The drum and shafts are made of galvanized steel. Both the drum and the motor have galvanized covers.

The standard motor is IP 54 2HP. The incremental encoder mounted is attached to the end of the drum shaft.

Side frames are heated.

An infrared photocell NPN, IP67 is installed on the inside of the side guide and detects the presence of a pedestrian or vehicle.

A bottom edge detector reverses the door when it hits an obstacle during the closing cycle. This detector can be either a wireless safety edge or a sensor that determines if the fabric can unroll properly. All hardware has
protective coating against corrosion.

Power to be 208, 230, or 480 volt AC, 60 Hertz, 3 phase. Circuit breakers to be provided by other: Consult factory for amperage. 480 volt
requires 120 volt for heater cables. Complete door assembly to be ready for connection to power. (Architect to designate responsibility for field wiring.)
