EVOSTA2 20-105/130 SOL PWM (1″) M230/50-60

Wet rotor electronic circulator designed for the circulation of water in residential building service with thermal solar collector heating systems. IPX5 protection. The circulator is ideal for replacing old three-speed circulators thanks to its compact size and all-round performance. A single key simplifies configuration. The included calcium removal cartridge keeps the motor shaft in perfect condition, preventing the normal formation of limescale that it can be generated inside the circulator if some air bubbles are present during the first installation.
