Viking HWS MK2 (Hot Water Suit)

Viking HWS MK2 (Hot Water Suit) | Hot Water Suits | The VIKING™ HWS MK 2 is manufactured from an abrasion resistant material which is also easy to clean, thus combining durability and comfort. The suit features a new unique "click" function valve with 3 flow settings and a dump mode for increased diver comfort. Both arms and legs are "open" without cuffs or seals at the ends so hot water can flush through the suit from the inside and out. The loose fitting collar is made of soft neoprene. The HWS MK2 also has two neoprene pockets positioned on the front thighs to carry items like tools and bolts.

HWS MK2 Material

Suit construction: 5 mm neoprene
Suit exterior: RO-TEX™ nylon with a PU top coating creates a very abrasion resistant exterior which can also be cleaned down after diving.
Underarm panels are constructed from 3 mm material for maximum freedom of movement.
The 2 front mounted pockets are also manufactured from the 3 mm material.

Seams are double glued, and then stitched using a heavy grade polyester thread. The seam that runs across the lower torso is additionally coated for protection from abrasion caused by friction and other sharp objects often found in the harsh underwater working environment.
2 front mounted 3 mm neoprene pockets with RO-TEX™ nylon exterior and PU coating for high abrasion resistance. 4 eyelets are built into each pocket for the attachment of accessories.
Valve and Water Flow
The VIKING™ HWS MK 2 features an internal diamond profile rubber tubing covered with a layer of neoprene for comfort. Strategically placed holes are drilled into the tubing, and hot water is pumped down from the surface, and dispersed around the inside of the suit through these holes. The water temperature is controlled from the surface via instructions from the diver.

Narrow gauge neoprene tubing is placed at the wrists and the ankles to allow water to flow into the optional hot water gauntlet gloves and hot water boots.

The new hot water valve, designed specifically for VIKING™, has a unique “click” function, with 3 flow settings and a dump mode. The flow settings are HIGH, MED & LOW, and represent flow rates of approximately 49 litres/min, 44 litres/min and 36 litres/min. The inlet valve is a standard banjo fitting, which attaches to a QD ½” male fitting which is attached to the water supply hose. The valve is mounted on the right hip and is easily accessible.

Hot Water Suits must be used in conjunction with an undergarment to protect the diver from accidental burning or scalding from excessively heated water. Typical undergarments would be neoprene suits or thermal undersuits.
