Images of ordinary maintenance of thermoregulation systems… or rather, not exactly ordinary, luckily. In this case, it is true to say that we found ourselves in front of electric heaters that had literally ‘exploded’.

This happened because the user had committed a serious imprudence: following the intervention of the high temperature safety thermostat, he had in fact ignored the alarm ‘bypassing’ it. The alarm was caused by poor oil circulation, for reasons related to fouling of the plant.

The scarce oil circulation therefore caused the intervention of the maximum temperature thermostat. By bypassing it, the customer caused the electrical resistances to break. Fortunately, everything was resolved with a shutdown of the thermoregulator, but the imprudence could have had even more serious consequences, for example if the oil had caught fire…

Preventive maintenance, evaluation of the manufacturer’s alarms, requesting the intervention of the service or telephone assistance, would have prevented everything.
