Engineering Excellence Of powerPerfector


Engineering Excellence

Installing any technology on the mains incoming supply to your building carries a risk. Our wealth of experience gained over the years has seen us develop industry-leading processes to mitigate this risk for clients.

PRINCE2 project management

We embrace PRINCE2 as a minimum standard for Project Management, meaning that your VPO® project is in expert hands and will be delivered safely, on time and on budget.

We have the capacity to up-scale to around 50 units per week if necessary. Our process is scalable and we have installed up to 60 units per week.

Approved Installers

Our SAFEcontractor accreditation is testament to our engineering processes and ability to manage our installers. Our highly trained NICEIC approved electrical engineers have each installed a minimum of 100 powerPerfector units and have been trained, assessed and are audited under the powerPerfector Low Voltage Safety Management System.

We regularly audit the quality of their work to ensure they meet the exacting quality and health and safety standards we demand for our clients.

Secure Supply Chain

From manufacturing to installation we have strict control of our units, which allows us to meet even the most challenging installation programmes with the help of our dedicated supply and logistics team.

Operational Support

Our engineers are on call 24/7 and work very closely with our approved installers. Our delivery partners are experienced in positioning units in the most challenging locations.

  • powerPerfector

    The powerPerfector optimiser alters the incoming supply voltage at a fixed ratio, and is suitable for most buildings. Optimisation settings are referenced from the logging of your building’s incoming voltage supply in order to maximise your savings.

  • powerPerfector Plus

    The powerPerfector Plus features dynamic Voltage Power Optimisation, in addition to the power quality improvements afforded by the standard unit. Suitable for electrical supplies with high volatility, the powerPerfector Plus will adapt automatically to changing voltage conditions to give an optimised output to maximise savings.

  • Build Quality

    Attention to detail, unique design and build quality mean that hand wound powerPerfector units achieve a peak efficiency of 99.94%.
