Marshall Tufflex Energy Management has entered the voltage-optimisation market with a product called Voltis and which is said to deliver demonstrable energy savings of 20%. Voltis constantly monitors incoming supply voltage, outgoing voltage and load being drawn and then adjusts automatically to harmonise power supply with demand — maximising savings and reducing carbon emissions.
It evens out peaks and troughs as the mains supply fluctuates and switches to standby if supply dips too low or a brown-out occurs.
The transformers are automatically rotated to prevent overheating. The system is also self cooling, either by fan or built-in air conditioning.
Marshall Tufflex Energy Management works with the Carbon Trust to offer interest-free funding for installations. Typical payback is within three years — much less for some clients.
