2 Furlex Electric
Furlex Electric is available as a complete kit for both on-deck and through-deck installation.
The electric system is also available as an upgrade of an existing Furlex by replacing the furling line,
drum and line guard assembly with the Furlex Electric Motor unit and related parts in the Furlex
Electric Retrot pack.
Low power consumption
High eciency throughout the electric power and control system. A “sleep mode” is activated to
save power when not in operation.
Powerful enough, but with precise torque limitation.
The electric motor has a computerised controller that monitors the current draw precisely. As soon
as it reaches a pre-set level it cuts out quickly enough to avoid damage to components. The torque
level is programmed into a memory chip so that each size of Furlex Electric has the correct setting.
Resistant to the marine environment
The gear house is machined from high grade corrosion resistant aluminium and andodized.
All stainless parts in 316 or 316L. The electric motor has its own housing which is completely sealed
and individually pressure tested before delivery.
Two speed operation
A double control button makes it possible to operate the
furler with great precision in the low speed mode.
By pushing both buttons at the same time, high
speed is activated.
Locks in both directions
The worm gear is self-locking (40:1) in both directions,
which means that the sail can be furled from either
the starboard, or the port side of the boat.
Emergency operation
The worm gear has a ½” socket that can be reached
from the starboard side. Seldén’s emergency line
driver is included in the delivery kit.
Compact size -minimised weight and dimensions.
The electric motor is compact, still giving enough power.
This is made possible by raising the voltage up to 42V.
Keeping weight and the dimensions in focus during the
design has resulted in a small unit.
