6. Electro Mechanical Linear Actuators
Electro Mechanical Linear Actuators are
compact and versatile units for transmission of
rotary motion into linear movement through
an overload safety system.
To operate signal systems, open blast furnace covers,
position conveyer gates, loading funnels, couplings,
guide cranes, tighten rail clamps and monorail
systems are all possible with the mechanism of
Electro Mechanical Linear Actuators.
It renders superfluousness flow in both the
hydraulic and pneumatic systems. It has a rigid
construction, is capable of withstanding different
environmental conditions and are capable of
operating optimally even in the most extreme of
conditions.
7. Electro Mechanical Rotary Actuators
A device that uses the conventional
motor power to supply rotational energy
in order to actuate and transmit rotary
movement.
An unbeatable combination at highest
torque, compact design , low breakdown
and economic price are the few
characteristics, which speaks the success
story of PREPEC Electro-Mechanical
Rotary Actuators.
Extensive testing and quality control
programs resulted in unparalleled reliability
also in closed looped system.
It is used for regulating the flow of fluids
through all types of valves, dampers, gates
etc.
8. Butterfly Dampers
Butterfly Dampers are used to control and
regulate air or gas at high temperatures and can
also be used as a shut off, regulator and isolating
damper.
PREPEC Single Flap Butterfly Damper model PDB is
compact and self contained device design and
fabricated for dependable and long operational life.
It is designed to be operated either manually or by
pneumatic or electric actuators and can also be used
with open or closed loop circuits.
These unique dampers are virtually leak proof and
uses a rotating disc principle. They are used when the
throttle of the air, gas, steam, liquids or fluids needs
to be controlled with a permissible leakage of 0.002%
to 3% of total flow.
These dampers can absorb piping stresses
and misalignment better and is comparatively lighter
in weight and has better mechanical and structural
properties.
9. Fire Dampers
PREPEC Fire Dampers have been
designed and developed to operate in the
hazardous application areas , which are
vulnerable to fire outbreak.
It has edge over the conventional Fire
Damper , which do not close completely ,
endangering the environment .
The flap of the Damper is generally kept
open with the Torsion Arm connected to a
fuse link.
This fuse link melts when the air
temperature exceeds the temperature rating.
This breaks the supports between the
Torsion Arm and the flap and the spring
contracts.
The Damper can be reset by installing new
fuse link.
10. Single Flap Multi Louvre Dampers
An ideally designed and developed custom built
device for Heat ventilation and Air-conditioning
Systems with proportional controls.
These are perfectly suited for regulating the flow of air
or gas in both moist and dry environmental
conditions.
The flap of the Damper, usually in a closed situation,
opens up as soon as the temperature rises above the
stipulated rate.
The fabrication is done to suit perfectly with the
process requirement.
The PREPEC range of Louver Damper Models are
compact, self contained units and have are highly
dependable with a long operational life.
The louvers are fabricated from structural steel in airo
foil design with reinforced inside to minimize the
resistance of air.
It comes with two blade arrangements, parallel or
opposed blade types.
11. Guillotine Dampers
A most efficient and reliable
leakproof guillotine damper
designed by 'PREPEC used in flue
and duct systems, where
positive shut-off isolation is
absolutely necessary.
Also used for the purpose of gas
cleaning and process
equipment isolation in many
industries.
PREPEC make Guillotine
Dampers have a special pin-rack,
screw nut and damper-drive system,
so probability of bladedropping and
consequent danger is very low, have
no seat cavity, thus no chances of
entrapment of flux.
12. Lifting Jacks
Lifting Jacks are used to lift loads
through a short distance.
The modular system and its
standardized components makes it
most suitable for easy installation
and maintenance.
The self-sustained type of thread
and locking system allows the load
to be fixed as desired and holds it in
its position without creep for
indefinite period.
PREPEC has to its distinction of
producing various range of Jacks
a) Screw Jacks
b) Worm Geared Jacks.
13. Winches
A specialty device among
hoisting machinery, winches are
used not only to life weights but
to also haul or erect them.
They are widely used in various
erection and repair jobs as well as
the construction of lifts. PREPEC
Winches are mainly classed
according to these parameters.
Means of Traction Employed -
Rope Winches and Chain Winches
Method of Mounting - Stationary
Winches and Mobile Winches
Type of Drum Used - Grooved
Drum Winches, Smooth Drum
Winches and Whelped Drum
Winches
14. Grabs
Crane Grabs are widely used in
transportation, logistics and packaging
scenarios. These specialized devices are
used to lift and shift loads and material.
When unit loads of given shape and size has to
be handled, considerable amount of time and
labour can be reduced by employing PREPEC
Grabs suspended from the crane hook which
grasp and release the load at almost no time.
Varying grabs are constructed to he reliable ,
compact , lightweight , convenient and safe.
PREPEC manufactures these types of cranes :
a) Orange peel grabs
b) Coil Handling grabs
c) Chain-driven clamshell grabs
d) Rope-driven clamshell grabs
e) hydraulic/electric clamshell/orange peel
grabs.
