Possible issues

Service interruption: for example refrigeration counters must operate continuously, in order to prevent significant damages such as costs of deteriorated products.


Faults and malfunctions: motors and electrical equipment not supplied under nominal conditions are subjected to a high failure rate and a lower useful life.

Electricity bills too expensive: mainly due to refrigeration, both for fresh products and in particular for frozen food. In fact, 50% of the energy in a supermarket is consumed by the cold chain.


The PQL solution:

It reduces the thermal and electrical stresses of loads reducing faults and disservices ensuring a continuity of the production cycle.

It checks and balances the power supply voltage of the electric loads (eg refrigeration counter motors): in order to have maximum efficiency and minimum consumption. Each refrigeration counter is composed by a combination of low power electric motors directly powered by a switchboard. Optimizing the input voltage can bring a significant advantage both in terms of saving and in terms of lifetime of the engine, which is considerably extended.

It erases or reduces the penalties for reactive energy: complying with the new AEEG Resolution 654/2015 / R / EEL enforced since January 2016.
