Brine Kit
This accessory is compulsory if a water temperature set point lower than or equal to +3°C is used (if the unit
is provided with double set point or variable set point, the lower set point is considered).
The accessory consists of increased insulation and suitable sizing and calibration of some components.
The inlet and outlet temperatures of the user-side exchanger must be given on ordering to allow correct set
-
ting of the alarm parameters and verification of the sizing of the expansion valve.
The cooling set point can then be changed by the customer in an interval that, compared to the set point given
on ordering, ranges from -1K up to the allowed limit temperature.
The unit will be optimized to work at the set point temperature given on ordering. For different set points, the
cooling capacity provided and the level of efficiency of the machine could decrease and move away from these
conditions.
This accessory obligatorily requires insertion of one of the condensation control options.
RPR
Refrigerant leak detector
This accessory includes a refrigerant leak detector. Detection of a refrigerant leak is managed by the controller
through a specific alarm and display of a specific icon on the display of the controller. This alarm stops the unit.
Accessory as an alternative to Refrigerant leak detector with automatic pump down.
Hydraulic circuit accessories
CFC
Flanged hydraulic conne counterflanges

Accessory supplied loose.
FVF
FLOWZER VFPP – Kit for variable flow rate primary circuit pump with bypass valve
included
Bluethink solution for a variable flow rate system, consisting solely of a user-side primary circuit.
Flowzer VFPP includes:
•
a pressure transducer installed at the ends of the user-side exchanger (Δp
e
)
•
a dedicated control system, installed at the factory in the electrical control panel of the unit (Sc)
•
a modulating bypass valve with servo-motor supplied separately with it (V
bp
), supplied loose (installation by
the customer)
•
two system pressure transducers (Δp
p
) supplied separately (installation by the customer)
The components above and the pump inverter must be selected at the time of the pre-sale agreements, de
-
pending on the features of the system. This has an impact on the quotation of the option and on the supply
terms of the concerned components.
In particular, the unit includes an additional control system, equipped with an advanced algorithm, which in
-
teracts with the main advanced Bluethink controller.
