This sounds like the heater is used only to bring the cell up to the operating temperature to trigger the reaction. I think they said the method of regulating the reaction is to vary gas pressure, rather than Rossi's method of changing the auxiliary electric heater power.
There appear to be substantial differences between the way Defkalion engineers the cells and controls them, and the way Rossi does. - Jed QUESTION Defkalion GT, In another thread you wrote, and I quote: Defkalion GT wrote: (there are no industrial secrets living in the electric heater or its role) In light of this, would you please tell us what purpose the *two* electric heaters serve in the e-Cat? From previous comments made by Rossi, I understand that the first heater is a "primary" or "main" and the second a "safety". Regarding the primary heater, how is it that a heater can be used to * control* the robust exothermic reaction in the e-Cat? If the primary heater is disengaged, does this cause the reaction to cease in a rapid fashion? And if this is correct, how can a second heater serve as a safety device? If the reaction can be controlled or shut down by removing power from the first heater, wouldn't engaging the second heater just re-start the reaction? Under which circumstances would the safety heater be engaged or disengaged? You can see how this may be confusing and appear contradictory - but the answers may lie in what is meant by 'safety' in this instance. Can you please explain the purpose and action of the safety heater - and who or what is being kept safe from what potential harm or other eventuality? Thank you in advance. Reasonable answers to these questions would be greatly appreciated by myself, and others as well. ANSWER In a post (viewtopic.php?f=3&t=54<http://www.defkalion-energy.com/forum/viewtopic.php?f=3&t=54>) we answered to one quiestion on our products functionality as follows: * Every kW Hyperion products is equiped with electronics and sensors that, among other, monitor in "real time" the mass/sec and the temperature difference (Delta) between output and input of the coolant in use (mass calorimeter). If this Delta is beyond a pre-defined point at products installation then: If it is a singe reactor unit, the reactor stops If it is a multi-reactor unit, then either some reactor(s) stop or all reactors stop based to a performance balance algorithm within safety/operational electronics. So, to answer your question: If you "consume" the heat energy, then the Hyperion continious to produce heat energy so you can achive max performance at any time of the day. If you do not "consume", Hyperion turns off and then on automaticaly.* The electric heating system is part of the switching system of our products. It is required to heat the reactor every time it is needed to be turned on, as already explained also by A.Rossi and described in his patent application. This switching mechanism is playing a significant role on the functionality and safety of our products. There is not any positive contribution from the electric heating system to the performance ratio of our products. Thank you for your question and your interest on our products.
