5. APPLICATIONS
EVOSTA2, EVOSTA2d 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, EVOSTA2d 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 stainless steel pump body.
–
EVOSTA2, EVOSTA2d circulators are self-protected against:
–
Overloads
–
Lack of phase
Excess temperature
–
Over-voltage and under-voltage
–
