MTX-R Extreme Cold Water Regulator

The MTX-R is based on the MTX military regulator and is a super tough, rugged, high performance, go anywhere regulator. The MTX-R has excellent cold water performance and has a greatly reduced risk of free flow, this has been achieved by improving several areas, including our innovative endcap solution that solves a long-challenged reality for cold-water divers of first stage freeze up. This regulator is designed to meet all aspects of the NEDU (Navy Experimental Dive Unit) military requirements for diving in extreme cold environments. The MTX-R is highly reliable and very easy to service.

FIRST STAGE
• Unique over-balanced diaphragm design – as the diver descends, the over-balancing feature allows
the medium pressure gas in the hose to increase at a faster rate than ambient. This results in superior
performance at depth
• Compact environmentally dry sealed diaphragm system completely eliminating the maintenance issues
associated with silicone, oil or grease filling
• Break through, innovative over-moulded first-stage endcap & environmental diaphragm helps prevent
ice build-up that can cause first stage free flow in extreme circumstances. Also protects the first stage
from impact damage
• Easy to grip DIN hand-wheel or over-moulded yoke hand-wheel, only requires one hand to release.
• Comes standard with 5 MP and 2 HP ports
• The 5th medium pressure port includes a protective bumper when not in use
• Forged first stage body with heat exchanging ribs for maximum thermal performance
• Angled HP ports for optimal hose routing and fitting of transmitters
• Forged rotating turret with medium pressure ports in a parallel direction for improved hose orientation
• Ribbed diaphragm clamp for improved heat exchange in cold water conditions
• Double swivel hose for greater freedom of movement and comfort

SECOND STAGE
• Simple to use with no diver adjustment controls and reduced chance of free flow occurrence, presettable
cracking effort or venturi control by an Apeks approved qualified technician
• High performance pneumatically balanced lever operated poppet valve
• Large, diver friendly self-flushing controllable purge button
• Front cover with over-moulded elastomer incorporates a formed chrome plated brass plate improving
durability of the second stage
• Large protective elastomer bumpers on the side and on the top to protect the second stage from
impacts and scratches in the most vulnerable places
• Reversible second stage allows for left or right hand configuration
• A heat exchanger (patented) which surrounds the valve mechanism, dissipates the cold caused by
gas expansion while drawing in the warmth of the ambient water
• Features an innovative Diver Changeable Exhaust system (DCE). The system gives the diver the ability
to change from a small exhaust tee to a large exhaust tee. The regulator is supplied with both sets
of exhaust tees
• Comfo-bite mouthpiece
• Flexible nylon braided hose has better cold water performance than traditional rubber hose
