Energy efficiency, as simple as VarSet
Engineered to meet your needs
Whether you run a single site operation,
or a globe-spanning enterprise, a fast and
easy way to enhance competitiveness is to
ensure that your power factor is corrected
and your electrical network delivering
optimum power.
Choosing advanced VarSet low voltage (LV)
capacitor banks is a simple and reliable
way to do that. Count on VarSet equipments
to bring true energy efficiency to your
electrical infrastructure.
High quality power = higher productivity
Power factor correction helps lower operating and capital costs and can provide
a very quick return on investment:
>Reduce capital expenses up to 30%.
Optimise electrical system capacity, avoid
oversizing and limit redundant capacity.
>Reduce reactive energy billing
penalties and lower operating
expenses up to 10%.
Boost power factor to lower utility bills
and reduce losses in transformers
and conductors.
>Reduce energy losses by up to 30%.
Optimise power consumption, reduce total
process energy consumption and reduce
CO2 emissions.
>Improve power system and
equipment reliability up to 18%.
