ECO-MAX Voltage optimisation is an electrical energy saving technique that is installed in series with the electricity supply to match supply voltage specific to the site’s equipment.
Voltage optimisation reduces the voltage of the electricity supplied to equipment, ensuring the excess voltages from the national grid supply isn’t used at the site. By simply rejecting and returning the surplus to grid, site consumption is minimised while remaining within the operating conditions specified by the equipment manufacturer.
Domestic units are fitted in a morning and begin to make savings straight away; commercial units are generally fitted in a day and bespoke, large scale industrial systems can take a little longer, but deliver enormous savings. 
Your Eco-Max home Voltage Optimiser is installed in series with the electricity supply. Typically this is under your stairs or wherever you mains electricity supply enters you home.
The Eco-max Commercial is designed for business premises and so will be installed wherever the mains supply enters you business property.
Large, bespoke Voltage Optimisation systems will take up a self-contained area of approximately one metre in a convenient position close to your electricity supply.
We offer three main types of Voltage Optimiser, as well as a range of additional modules for a more comprehensive energy saving solution.
• Eco-Max Home – Single phase for domestic and small commercial use
• Eco-Max Commercial – 3 phase, up to 1200 Amps
• Eco-Max Power – up to 4350 Amps bespoke for large industrial size installations
