Viking HWS (Hot Water Suit)

The Viking Hot Water Suit (HWS) features a suit made from a unique rubber based material – Viking VSN material. It has a core of black EPDM/natural rubber, which is covered with stretch Armatex Nylon on both sides. Technically it is a vulcanized rubber suit, but without the vulcanized "style" appearance. Primary advantages of the VSN material are that the body is thin, flexible and very hard wearing, but most importantly, does not shrink when constantly dried in an industrial dryer. The suit is fitted with a tube system on the inside for dispersion of the hot water, covering torso, arms and legs. On/off valve on the outside of the right leg has a maximum working pressure of 40 bar. Lower front legs and knees are covered with black rubber reinforcements for additional durability.

A flexible and stretchy knitted Armatex Jersey Nylon covers both sides of a mid-ply of black NR/EPDM rubber. Material construction is in that sense a trilaminate material comprising qualities as outstanding flexibility, comfort and durability. It has an average material weight of 1100 g/m^2. As such, it has the comfort of compressed neoprene combined with the durability of vulcanized rubber. The material is totally non-compressible which means no loss of buoyancy or insulation while diving. A special advantage of using VSN material for a Hot Water Suit application is its ability to withstand shrinking when constantly being exposed to the heat from industrial dryers.

Stitched seams are covered both on outside and inside of the suit. The outside seams are covered with a durable elastic nylon ribbon whereas the inside seams are pre-treated with a special rubber solution for both reinforcement and protection prior to vulcanization. Together it creates a very tough and hardwearing seam.

The water flow is controlled by an ON/OFF valve designed specially for Viking, with 6 water feeds, and fitted to the right hip of the suit. The operating knob is designed for ease of operation, and has a maximum W.P. of 40 bar. The banjo connector is a standard QD 1/2" male fitting.

Viking Hot Water Suits should always be worn with an undersuit in order to prevent the possibility of burning or scalding the diver with water which is too hot.
