Thermal Coil Reduces Risk of Cold Water Diving Regulator Freeze

DIVE Report

Atomic Aquatics has launched its latest cold-water diving innovation, Scuba Heat, a thermal coil designed to warm air from a diver's first stage to ambient temperature, in order to prevent their second stage from freezing and free-flowing in cold water.

The Scuba Heat coil is slightly smaller than a pony bottle mounted on a diver's tank band, and connected with standard hoses and fittings between the first and second stages. As air from the first stage enters the coil, it is warmed by the surrounding water before exiting the coil towards the second stage. There are no moving parts, batteries or heating elements.

The heat-exchanging coil is made of a thermally conductive and corrosion-resistant copper-nickel alloy which, according to Atomic Aquatics 'will not reduce airflow or otherwise degrade your regulator's performance.'

In addition to the reduced possibility of regulator freeze, Atomic Aquatics' test divers reportedly found that they were more comfortable underwater as their body core temperature 'was not cooled down with the super cold air entering [their] lungs' and that their hands and feet felt more comfortable.
