* The benchmark for the most efficient circulators is EEI ≤ 0.20

Yonos MAXO-D

Design

Glandless circulator with threaded connection or flange connection, EC motor with automatic power adjustment.

Application

Hot-water heating systems of all kinds, air-conditioning systems, closed cooling circuits, industrial circulation systems.

Equipment/function

Operating modes

n = constant (3 speed stages)

Manual functions

Setting the operating mode
Setting of pump output (delivery head)
Setting the speed stages

Automatic functions

Infinitely variable power adjustment according to the operating mode
Deblocking function
Soft start
