Temperature Protection
The Dna 40 is the first power supply for electronic cigarettes to directly measure
and limit the temperature of the heating coil during operation. By preventing the
coil from becoming too hot regardless of fluid, wicking or airflow, a variety of
undesirable situations can be prevented. For example, appropriate temperature
settings will prevent the wicking material from charring, which compromise taste
and introduces unintended chemicals into the vapor. Appropriate temperature
settings will also reduce the breakdown of flavoring and base liquid components,
which could impact taste or safety.
Evolv’s Temperature Protection Technology requires a heating coil made from
Nickel 200 alloy, rather than Nickel Chromium or Kanthal alloys. Nickel 200 is
commercially pure nickel. It is often sold in vapor shops and online as
”non-resistance wire”. If the temperature reaches the maximum value, the wattage
applied to the atomizer coil is reduced to prevent overheating. Please note that the
temperature reading is the average temperature of the atomizer coil, and care
should taken to construct the heating coil so that the temperature is uniform,
without hot or cold spots. Ensure that the coil does not short to itself.
