World breakthrough in electrical safety.

Device is currently being purchased by multiple Blue Chip companies.

The OPEN Pen device since its launch early in 2019 has already seen its technology added to the latest amendments to the IEE regulations (see Am 1 EV and Am 2 DPC).

This has opened up a massive Global EV market opportunity for the product.

No More Earth Electrodes !!

The O-PEN device can detect load imbalances under all conditions including open PEN on three phase TN-C-S (PME) infrastructures, and safely isolates the incoming supply or individual loads.

Allowing the installer to utilise the PME earth, guarantees earth resistance values are maintained all year round while offering a safer solution during installation as it removes the risk of striking buried services with Earth electrodes. The device also dramatically reduces installation cost!


EV Market

Most major EV Charger unit suppliers have now used the OPD device and in many cases, this has led them to specifying the device. It is now widely used throughout the UK and its reputation is growing daily.

This device will transform EV Charging Globally and ensure installation cost is dramatically reduced. The OPD gives a far better protection than a simple earth rod installation and with respect to multiple supercharger installations, a rod mat has to be installed to ensure a constant resistance is found, which is costly (£10,000 per Mat Installation and time consuming), this cost of £10,000 per installation is now eliminated by installing the OPD Product into the installation.


Commercial Building Market

Broken Neutral faults on TN-C-S systems are extremely dangerous as the single-phase voltage will rise to the three-phase level subjecting your equipment to >400V instead of 230V.

This results in over voltage that can be catastrophic as any electronic appliance connected to the wiring will most likely be damaged due to overheating, resulting in expensive insurance claims and be a potential FIRE HAZARD!

Furthermore, electricity would travel to Earth through a different path. This may be via water pipes, stoves and metal taps or any other bonded appliance that is a conductor of electricity.

This is very dangerous, as you would suffer a serious electric shock if you touch something where electricity is present. RCD’s and MCB’s currently used DO NOT offer any protection against this fault condition.

Broken PEN conductors present significant hazards withing buildings including the risk of electric shock and can create heat build-up which can lead to fire.

When the PEN conductor fails, not only does this present a shock hazard but the diverted neutral current can also create a significant heat build-up, as it typically makes a circuit via exposed metalwork (such as gas, water and oil pipes, etc.) - which can then lead to fire.

PEN conductors serve as both a protective earthing and neutral conductor. Although PEN conductors within installations have been prohibited for some time now, older ones still remain in, for example, the rising mains in blocks of apartments and military camps, open-circuit PEN conductors might be a growing problem due to a range of factors - including our ageing distribution system, metallic service pipes being replaced and the theft of copper from cables.

Data obtained from the Health and Safety Executive shows at least one incident of an open-circuit PEN conductor is reported every day - with around 10% of them leading to injury. As many incidents go unreported, it's believed the real figure could be significantly higher.

The Solution

Property Management Companies throughout the world will now be able to offer their client base the safety aspect that only OPD can give. This will allow a Monitoring System to fully utilize the capabilities of the OPD product in terms of early warning of risk disaster to Schools, Universities, Office blocks and high rise residential buildings.

Our commercial device opens up a phenomenal market for our future distributors of the product in their territory.

While at the moment the Device is for 3 Phase Electricity with strong inquiries now coming in with regard to housing in the Middle East and the Australia/New Zealand Regions as the residential is on 3 Phase, announcements are already being made in some countries with residential on 1st Phase electricity that by 2030, all residential will be on 3 Phase, not just commercial buildings. Therefore this in turn opens up even greater markets over the next number of years for the product as the OPEN PEN Device is the only product that can provide 100% protection.

Globally the RCBO product sold Billions of Units over the years but did not detect an Open Pen Fault which means the market potential for the OPD is enormous as it is owned exclusively by Greentec International.

O-PEN offers full protection to the building and user in the event of a broken supply Neutral event.

Revolutionary Breakthrough in Electrical Safety

Many cities across the world have poor and unreliable "as built drawings". This leads to huge expense in time and money when installing traditional supplementary earthing systems.

O-PEN technology can detect load imbalances and dangerous touch voltages and OFFERS FULL PROTECTION to the building and user when a dangerous event occurs, which can lead to:

Single-phase voltages rising to 400V

Over heating of appliances

Potential fire risk

Danger of death from electrocution
