Since 2005, Vanguards Power (Hong Kong) Limited (VPHK) has been designing, developing, manufacturing and selling Energy Saving Systems for homes & offices. We supply our Power Optmisation Systems through our trained and appointed Channel Partners worldwide. Where no Channel Partner exists in a region or country we will only supply single phase products to bonafide companies. We do this to maintain the highest standards of safety and customer care. We do not supply 3 Phase Products to any party other than our trained Channel Partners.
