5. APPLICATIONS
EVOSTA2, EVOSTA3 series circulators allow integrated adjustment of the differential pressure which enables
the circulator performance to be adapted to the actual requirements of the system. This determines
considerable energy saving, a greater possibility of control of the system, and reduced noise.
EVOSTA2, EVOSTA3 circulators are designed for the circulation of:
–
water in heating and conditioning systems.
–
water in industrial water circuits.
–
domestic water only for the versions with bronze pump body .
EVOSTA2, EVOSTA3 circulators are self-protected against:
–
Overloads
–
Lack of phase
–
Excess temperature
–
Over-voltage and under-voltage
