The InverECO features InverMAC technology, Madimack's enhanced inverter technology, which optimizes pump motor control. The result is a considerable reduction in energy consumption and operating noise. For backwashing, the InverECO can operate at 100% speed. On the other hand, during daily filtration use, which requires a reduced flow rate, the pump aligns itself and reduces its output. Double energy-saving InverEco operates at full speed at the start of the season to heat your pool faster. Once the set temperature has been reached, it switches to low-speed mode and maintains a stable temperature throughout the season. InverEco saves twice as much energy as a single-speed heat pump. COP UP TO 11.6 Based on the principle of low-speed performance, lnverEco can achieve a COP of up to 11.6 when operating at 20% capacity.
