Technical Systems: Double line (Duomatic) – The BEST
In heavy duty conditions, such as cold or heat
extremetemperatures, dirt or wet environment, RIVI’s double
linesystems offer a reliable method to lubricate friction points.
Thiscentralized system is able to supply lubricant to lube
pointsefficiently. Double line systems allows even more flexibility
indosage of lubricant, by combination with progressive
Quicklub.
The double line system is possible to be refurbished at
anytime,even with automatic grease recovery systems.
Features:
• Grease protection (bleeding or oil separation)• The smart
version allows to work even under Offshore or
Cold Climate Conditions.• Useful life higher than 30 years.•
Suitable for every greases• Visual or electric monitoring
(optional) .• Simple and individual dosage – each couple of
outsides can
be adapted individually.• Stainless steel components available•
Maintenance‐free

Technical Systems : Single Line (CentroMatic) – Efficient &
Multipurpose
The CentroMatic systems are used when the lubrication needings
implies frequent lubrication cycles of smallgrease volumes.
CentroMatic injectors – direct action – has a metal to metal
adjustment, and pistons capableof deliver lubricants even at high
pressures. Each injector is individually driven, and supply to only
onelubrication point. It can be adjusted with high precision to
supply the exact quantity of lubricant required.Whenever the
pumpstation be powerful enough, and piping size be appropriate, the
entire lube system can beexpanded at anytime. Single line system is
possible to be refurbished at anytime, even with automatic
greaserecovery systems.
Features:
• Grease protection (bleeding or oil separation)• Under a proper
design it allows to work even
under Offshore or Cold Climate Conditions.• Useful life higher
than 30 years.• Suitable for most greases• Visual or electric
monitoring (optional) .• Simple and individual dosage•

Technical Systems: Multiline & Progressive system (Quicklub)
– Reliable @best price
The Quicklub systems have been designed to satisfy the most
restrictive lubrication requirements of machinesand equipment. Its
reliability is based on the principle of progressive function,
where the lubricant is deliveredto the lubrication points by
pressure‐driven pistons. The lubrication occurs in intervals
regulated a maximumpressure of 350 bar. So that, the lubrication of
the lube points is also feasible even against high
backpressures.
QuickLub systems can service up to three independent circuits,
each one with its own pump elements andnumerous lubrication points.
Every Quicklub system is easy to monitor and it ensures that the
precise andmetered quantity of lubricant reaches to each one of the
lubrication points connected to the system.
QUICKLUB system vs CENTROMATIC system
Features:
• Under a proper design it allows towork even under Offshore or
ColdClimate Conditions.
• Useful life higher than 25 years.• Suitable for many greases.•
Electric monitoring (optional).• Easy to control and maintain.•
High quality @affordable price

Technical Systems: Automatic Grease Recovery (AGR) – Innovation
& Efficiency
This system is usually combined either with DUOMATIC or
CENTROMATIC automatic lubrication systems. It canalso be installed
stand alone.
It allows to collect the grease which flows out from the
bearings, and forward it to a centralized box. This waythe former
plastic bottles become outdated. Maintenance staff only must fill
the automatic system reservoir,and replace the plastic bag inside
the collecting box.
Features:
• Under a proper design it allows to work evenunder Offshore or
Cold Climate Conditions.
• Useful life higher than 30 years.• Suitable for most greases•
It makes easier the yearly maintenance.• It helps to keep low the
pressure inside the
bearings (slewing rings, main bearings…).• It ensures balancing
between greasing in & out• Electrical monitoring is possible
(optional).

The best way to lubricate gears (pinion‐crown), when compressed
air is not available or affordable.Lube pinion receives lubricant
by using any standard lubrication system (multiline, progressive,
etc…) andevenly applies the lubricant precisely on the flank of the
pinion teeth, just on the contact surface to thecrown teeth. It
fixes perfectly to the Pitch or Yaw drive pinion. The modular
design implies the best reliabilityto an affordable price.
Products: Lube pinion (PU) – keep your gears on motion
Features:
• It is able work even under Offshoreor Cold Climate
Conditions.
• Suitable for every greases.• Corrosion resistant• Light, easy,
efficient, robust.
• Grease outlets ensures optimalgrease layer on the tooth flange

Microlubgear is a novel technology to avoid the energygeneration
loses to lubricate the pitch at 0º position. This device– combined
with a right Automatic Lubrication System –lubricates the tooth in
contact while the wind turbine operatesand pitch system is
working.It can be adapted on every platform of WTGs – with
electricalpitch system, and also for yaw gears – from serial
production oreven be retrofitted on operative wind farms. It can be
alsointegrated in automatic lubrication systems based on
lubepinion
Products: MicroLubGear – Innovation state‐of‐the‐art
Features:• Suitable for Onshore & Offshore WTGs• Suitable
for CCV WTGs (Cold Climate Conditions)• Pitch and Yaw gears.•
Improve lubrication system it belongs to.• Mend the grease film on
gear teeth.• Optimize grease consumption.• Prolong gears useful
life.• Extend maintenance intervals.• Increase Energy Generation.•
Light, efficient, robust.
