Sweet Energy Savings at Mentos
22 Jun 2015

mentos2

A few years ago Breda Perfetti installed new HID lamps with electronic ballasts. They found that this technology required frequent maintenance and was not stable. Breda was replacing the fixtures every few years. Following HyTeps energy consultation, Breda chose to replace their lighting circuits with conventional lighting fixtures in conjunction with the installation of PowerSines Light Energy Controllers (LEC).

ComEC PowerSines - Gioiellerie Beaverbrooks
22 Jun 2015

Beaverbrooks

Come parte della strategia di bilancio per l’anno 2011, Beaverbrooks ha deciso di ridurre la spesa elettrica e le emissioni di CO2. Insieme a PowerSines il Gruppo ha identificato la tecnologia del ComEC come mezzo raggiungere questo obiettivo sfruttando l’ottimizzazione della tensione. L’ottimizzazione della tensione con il ComEC PowerSines ha permesso a Beaverbrooks un risparmio del 19,9% sul totale dei costi elettrici superando le iniziali aspettative dell’azienda.

ComEC SL - Risparmio energetico da McDonald’s
22 Jun 2015

McDonalds

McDonald's ha scelto di utilizzare il sistema universale di controllo di efficienza energetica di PowerSines per applicazioni commerciali (ComEC). ComEC controlla dinamicamente e stabilizza la tensione erogata a tutti i carichi, garantendo la fornitura di energia ad un adeguato livello di tensione, di giorno o di notte, e generando un risparmio energetico immediato fino al 18%. Inoltre, attraverso la stabilizzazione e il controllo della tensione, ComEC migliora il fattore di potenza, impedendo guasti alle apparecchiature, prolungando la loro vita e riducendo i costi di manutenzione.

Tholos - Motori elettrici
18 Jun 2015

cofely9

Tholos ha condotto un Audit energetico su circa 60 motori di potenza superiore ai 15 KWe allo scopo di individuare la possibile installazione di inverter. Dopo una prima analisi, sono stati individuati circa su 40 motori, che alimentano ventilatori e gruppi di pompaggio, con potenza complessiva superiore ai 2 MWe su cui è conveniente installare sistemi elettronici di controllo della velocità. I risparmi complessivi stimati sono superiori ai 300 KWe, con un risparmio annuo minimo pari a 2.100 MWe pari a circa 170.000 €/anno.

SPP Pumps - Aeration Injection Pump System
18 Jun 2015

cofely6

Pumps will not always show obvious signs that they are working inefficiently except when you see the electricity bill or maintenance is scheduled. In some cases a pump in distress can easily be easily spotted through vibration, temperature, noise or leakage. It is worth noting that pump systems are often operated as they always have been. Even noise and vibration levels can be accepted because they have always been at that level.

Therefore, the analysis of the pump system in an installation can result in significant energy savings.
