The Torq-master 2000 has been used on hundreds of pumping applications,
on sizes ranging from 5.5kw to 550kw
We recently supplied 25 stand alone soft start panels
built to customer specification for Selwood Pumps Ltd as part
of their hire fleet. These units had to be of robust construction
on a 12" stand along with a Drip Shed. Also various plug
and socket arrangements were used for easy customer connection.
Ralspeed also designed a soft start system for fire pump application,
where at full speed, the electronics switch off completely,
the by-pass contactor holds in and in the event of a fire the
machine will 'run to destruction'. One such system was supplied
through Parmley Graham Ltd to Rosyth Dock Yard for their 250kw
fire pump system.
Compressors/Chillers
Ralspeed have successfully started many different types of compressors
and chillers. Such applications have recently included;
31 Carrier chillers at Canary Wharf, London, using Torq-master
2000 Soft Starters ranging from 450kw to 750kw. The total
power being 17.4mw.
3 York Screw Compressors installed in a fish freezing plant
at Peterhead, using 3 x 560kw Torq-master 2000 Soft Starters.
A Grasso Screw Compressor which was installed in a Pea Freezing
plant at Eyemouth, using a 450kw Torq-master 2000 Soft Start
unit.
An Ingersol-Rand 'Centac' compressor recently commissioned
at Allied Turbo's Skelmersdale, using a 450kw Torq-master 2000
Soft Start unit.
Ralspeed have completed many projects involving various different
types of rock crushers. Impact Crushers, Jaw Crushers and Cone
Crushers have been successfully started using the Torq-master
soft start unit. Recently completed projects include;
5 Impact Crushers for Powerscreen Canaries S.L. using
160kw and 200kw soft start units on generator fed applications
in Tenerife, Lanzarote, and Fuerteventura. All of these soft starters were manufactured by Ralspeed into robust Enclosures
and to customer specification.
200kw Mobile Impact Crusher, which utilised a Ralspeed Frequency
Converter to accelerate the motor to speed in less than full
load current (approximately 190A) to minimise the size of the
generator required on the mobile chassis.
Ralspeed have successfully applied many soft start units on
fan applications, here are just a few;
One such application involved supplying Dam-Head Creek
Power Station with 3 of our 186kw soft starter panels, again
built to customer specification with top entry required and
short delivery time was achieved.
As well as the soft starters we have also built many frequency
converter panels for Swift Air Movement Ltd who require a particular
system involving 2 frequency converters in 1 enclosure along
with a remote control system for supply and extract in kitchens.
The Torq-master 2000 soft start unit has been used on many different
'off-shore' applications.
We have recently commissioned a project for BAE systems
aboard RFA Wavenight and RFA Wave ruler, Auxiliary Oilers.
In total 16 x 200kw Torq-master 2000 Soft Starters were used
to drive high pressure water pumps which are pressurising
the fire protection system.
As well as the soft start units we have also supplied frequency
converters for on-board ship application. One such application
was on board the Toisa Polaris Diving Vessel, which used a 250kw
frequency converter to drive a Comp-Air Compressor. The reason
for using the V.S.D. was to illuminate the effects of interference
of the mains supply generated by the main electric propulsion
system.
