The technology of the immersion heater Teflon®, entirely realized in our workshops, is based on a cable heating of weak load and inertia thermics, which allows a soft and precise diffusion of heat. It is then formatted so as to obtain a large surface of exchange in small overall dimensions. This weak load generates one lifespan of the immersion heater but as product heated more important as with a traditional immersion heater of higher load. The range of power S `extends from 0,5 kw to 15 kw.
