The circulators must never be used for the circulation of domestic
water or in the foodstuffs field.
The circulators must never be used in refrigeration systems, air
conditioning systems and similar installations.

* To avoid condensation in the motor and the electronics the temperature of the pumped
liquid must always be greater than the ambient temperature.
** To avoid cavitation noise, minimum pressure values on the intake opening must be
strictly respected.
*** The benchmark for most efficient circulators is EEI ≤ 0,20.
2.3 Description of the circulator
Wet rotor circulator with integrated frequency commutator (INVERTER).
No mechanical seal is required. No protection against overload is required. The
motor is protected against short-circuit operation.
The motor is integrated with an electronic module allowing the adjustment of the
head/pressure difference from 1.7 m to 5.7 m (with Q = 0 m
Adjustment elements located on the terminal board box:
- Trimmer to adjust the rotation speed value set at output.
- Warning light (LED) of commissioning / fault signaling.
