Only our system can guarantee a continuous flow of acid all day and night- even at different temperatures and humidities.
The key is our patented 2-wick-system. the first wick drops a contiousous flow of acid ont he second wick.
there appears the acid as a wet spot, that automatically grows bigger, if the evaporation-conditions become worse, such as lower temperature. The bigger spot has more evaporation-surface and this bigger surface always (between temperatures of 12°C-35°C) ensures the evaporation of the dropping acid from the first wick. In the oworst case the big, horizontal wick is completely wet.
No other evaporator/pad has such a big evaporation-surface which is even self-adjusting.
