Are beautiful ? Yes, but also very useful. The leds in our tempering machines Proxima, Compatta and Prima (these at Host!) are not only beautiful and stylish ...! The red leds have two strips: one lower strip that is activated fully since starting the heater while the second is completed entirely, led after led, when temperature is reached. Also the blue led are 2 strips: here too, the lower lights when activating the tempering process while the upper lights completely when it reaches the set temperature. That's all? No, when you stop working you set the "night" and activates the automatic turning off that safeguarding the savings of energy. The upper blue light will turn off completely only on reaching the rest of the machinery so that the user always knows in which mode is the tempering machine.
