Speed-Guardian™ 4000 H and V Acoustic

Acoustic Model With High Lift Track Application 1-5/8" (42 mm) Panel

The H high lift track application makes it possible for the door to be installed behind or above supply lines or crane tracks. The 1-5/8" (42 mm) thick panel is guided in horizontal tracks and can be diverted flexibly depending on the application. Thanks to the belt mechanism with counter weights, the door is especially low-wear and long-lasting.

Acoustic Model With Vertical Lift Track Application 1-5/8" (42 mm) Panel

With the V vertical lift track application, the 1-5/'8" (42 mm) thick door panel runs vertically along the building wall allowing for very quiet and wear-free door movement. The belt mechanism with counter weights guarantees a long service life with constant use.

Acoustic Panel Insulates Sound Up to 31 dB

For special applications that require acoustic insulation for sound-deadening, the Speed-Guardian™ 4000 A high speed door has a 1-5/8" thick panel made of smooth C0 anodized aluminum with aluminum hollow profiles. The hollow profiles are filled with 5 mm PVC and 30 mm PU-foam, providing acoustic insulation up to 31 dB.

NEMA 4X Smart Start™ NXT Control Box - Standard

All 5000 models include our Smart Start™ NXT, NEMA 4X, control box as standard.  The updated control box has a simplified wiring configuration and is more powerful with fewer components and cables as compared to the original Smart Start™.  A distribution block accepts the activation and protection device wiring; main power cables feed through pre-drilled holes on the bottom of the box where the individual wires, with pre-wired removable terminal blocks, simply plug into the circuit board.  There are extra ports on the control board allowing for firmware upgrades and future expansion.  A USB port is included for maintenance monitoring.

Built-in Light Grid

The standard light grid is integral with the guide tracks making it less susceptible to damage by passing loads.  This system enhances protection of personnel and goods and drastically reduces the likelihood of damage and repair to other parts of the door, saving on maintenance costs.

R-value refers only to the panel's resistance against energy loss. U-value is an internationally recognized measurement tool that provides data about the energy flow lost through the total panel construction including the panel, seals, windows, etc. The 5000's solid sections provide the most efficient U-value available today.
