Apeks MTX-R Octopus

Free UK delivery on all orders over £50


  • Description

    The Apeks MTX-R Octopus delivers the same outstanding cold water performance as the MTX-R regulator but is finished with a high visibility yellow front cover, inlet trims and low pressure hose. The MTX-R range were designed in accordance with theUnited States Navy Experimental Dive Unit extreme cold water test.

    As with the primary regulator, the octopus does not have any diver adjustable controls and has been specially adjusted and modified for optimal performance in the extreme cold water conditions specified in the US Navy test.

    To help combat ice forming on critical components in near freezing water whilst performing at 60m the octopus is fitted with a large heat exchanger around the hose inlet that works to draw the cold created in the pneumatically balanced valve as the compressed gas from the first stage is depressurised into thehousing. At the same time it also helps to transfer heat from the surrounding water back into the valve and housing.
