Northern Divers Hotwater Suit, Evolution 8

hotwater suit evo8 350 350hotwater suit Valve 03b 350 350

Our Hotwater Suit Evolution 8 has been developed over the last 20 years. It has been tested under the UK Balmoral platform in the North Sea, at a depth of 355 metres. It is trusted by commercial divers and schools around the world.

The ergonomically designed suit is based around our unique heavy anodised water distribution valve, which includes a 360° stainless steel quick connector. The water flows through an anti-kink flat rubber pipe system, with the flow rate controlled by the diver. The pipes are directed for comfort and have a padded neoprene cover – perfect for those long bell runs. When the water distribution valve is not feeding the suit, it dumps to the rear. This function is selected via a control knob.

There’s a handy eyelet on the front of the chest which houses a hot water pipe (inc plug). This can be used to heat the diver’s faceplate to improve visibility.

The suit body is manufactured from specially developed anti-shrink neoprene with a high rubber solids content and a durable Swiss pique outer lining.

Tested to BS EN 14225-3:2005 by an independent notified body.
