Latvian Boiler Company Cuts Costs And Noise With Commander
SK
One of Europe’s leading suppliers of boilers, for use with
wooden pellets as fuel, has upgraded its products, saving costs and
cutting operating noise, with the introduction of variable speed AC
drives from Control Techniques.
SIA GRANDEG, based in Latvia, manufactures a
range of wood pellet fuel boilers with heat outputs between 15 and
500 kW, for both domestic and commercial installations. The biggest
growth potential for this successful and rapidly expanding company
is seen to be in the domestic sector in northern Europe, Russia and
other (CIS) countries, where a sophisticated product is
required.
As part of its drive to develop its product range
for these export markets, GRANDEG brought in Control Techniques’
representatives in the area, EMT of Riga, who proposed a new system
of control of the screw feeders to improve performance and reduce
energy and maintenance costs. Now, 0.25 and 0.5 kW Commander SK AC
drives are being provided to give smooth and accurate control of
the screw-feed motors to give a supply of wood pellets.
“The relay was proving to be too noisy
for a domestic setting and now the whole system starts, and runs,
almost silently,” he says. “Because of the reduced stresses on the
bearings and other components, the general reliability and lifetime
costs are much reduced. What’s more, because the drive has
comprehensive diagnostics on its screen, most often problems can be
resolved with a telephone call, eliminating the costs and resources
required for a call-out.”>>>>>>>
