  • Description

    The Apeks MTX-R Stage 3 Regulator Set combines the extreme cold water MTX-R regulator and MTX-R octopus into a ready to dive set. The MTX-R regulators were designed in accordance with theUnited States Navy Experimental Dive Unit extreme cold water test for unbelievable performance and reliability.

    The first stage body of the MTX-R is forged for the bestthermal performance and then has been covered withheat exchanging fins to increase the surface area andfurther improve the cold water performance and help prevent ice formation.The first stage uses an over-balanced diaphragm design for consistent performance throughout the diver and has been environmentally sealed to protect the internal components from the effects of the extreme cold at depth and also prevent contamination.

    There are four low pressure ports on a parallel port turret with a fifth high flow port under a protective cap. A high pressure port can be found on either side of the main body and are pre-angled for optimal hose routing.

    The MTX-R second stage hasa large heat exchanger around the hose inlet to dissipate the extreme cold temperatures generated in the pneumatically balanced metal valve as the compressed air depressurises into the housing. Unusually, the second stage has no diver adjustable options and instead has been modified and adjusted to minimise the risk of a second stage free flow.The second stage is tough and robustly made with a wide exhaust deflector and fitted with the typical Apeks regulator mouthpiece for excellent comfort and hygienic properties.

    The octopus delivers the same performance and cold water reliability as the second stage but is finished with a high visibility yellow hose, front cover and trim.

    With an innovative first stage design that helps to prevent ice build up around the diaphragm, the MTX-R is reliable, rugged and expedition ready.
