Specialist IP Ratings - IP00 to IP66

All our units can be enclosed across the full range of IP ratings - from IP00 products for our OEM customers to IP66 for external or roof installations, we can provide any rating as required.

Our specialist applications and flexibility allows for truly bespoke solutions in the most demanding environments. We've recently helped one of the leading renewable energy providers in the UK to deliver a sub-sea product, that encloses our EM Stabiliser in an oil filled unit on the sea-bed.

This revolutionary solution reduced the need to upgrade the existing sub-sea cable size and saved over £1m of costs, giving an almost instant return on investment.

Street Furniture

Our vandal proof enclosures allow Governments and town councils to install stabiliser technology at local street level sites to maintain supplies to lighting and traffic enforcement equipment, whilst reducing energy consumption and protecting systems from surges and power spikes.

Remote access to the units can allow for voltages to be turned down from a control centre, to balance energy supplies and reduce energy consumption as electricity demand changes.
