Just got a new triton tank, and have read that the 0.3ohm coils are rated at 55-65w, whereas the Atlantis 0.3ohm coils are rated 70-80w. Now as these coils are interchangeable, are the 70-80w 0.3 coils now obsolete or will they still be produced?
They should still be produced. The 0.3 Ohm Atlantis coil is a dual coil Kanthal wire and the 0.3 Ohm Triton coil is a single coil Surgical Stainless 316L wire. That is why the Atlantis needs more power and handles more wattage.
