Several
hundreds of PROFURL electric or hydraulic genoa reefing
systems have been supplied over the past 13 years, making
PROFURL the first manufacturer of this type of systems
in the world.
The main features of these systems are a high output and
a great reliability. This new range of PROFURL motorised
systems includes the very latest improvements in modern
technology, allowing for a compact and modern design.
PROFURL motorised systems are covered by a 3-year worldwide
warranty.
The
special grade cast aluminium housing is treated against corrosion
by an oven baked paint finish. All stainless steel parts are
insulated from the aluminium housing with insulation bushings.
The very fine tolerances of the gears and transmission assemblies
produces very quiet operation. The gearbox is lubricated for
life in an oil bath and requires no maintenance.
The self-locking mechanism is non-reversible, thus requiring
no manual locking to immobilise the extrusions when the sail
is furled or reefed. The sail may be furled equally well in
either direction depending upon which side the sails UV strip
is sewn.
The gear ratio has been optimised to produce a high output with
an ideal speed of rotation, this minimises flutter damage to
the sail when reefing.
The lower part of the gear motor includes an adjustable stainless
steel tube connecting the housing of the motor onto the lower
toggle (supplied).
The PROFURL motorised systems are subjected to severe tests
on a special test bench. Torque output is carefully measured,
as is the speed of rotation and power consumption.
Luff
extrusions are identical to the ones used with the manual
PROFURL models. They can easily withstand the high torque
produced by the gear motor.
Extrusions are delivered in 2-meter sections, linked by
the unique patented PROFURL connectors.
Self-lubricating
Nylon graphite bearings are fitted at each joints, and
prevent wear, corrosion and noise.
The
high output of the gear motor requires a 100% fail safe
device to prevent the halyard wrapping around the forestay.
When operating a manual system an increased tension on
the furling is an indication of a possible halyard wrap.
In the case of a motorised system such an early warning
is not possible.
The patented PROFURL Wrapstop eliminates any possibility
of a halyard wrap.
