Salinity control unit TDS Electric light
For ≤ BX 600 , ≤ BNX 1000 and ≤ SIXEN 2000 generators, electrically and hydraulically assembled to the generator.
The TDS control system limits the level of salts and minerals dissolved in the generator water within the value allowed by the
manufacturer, thus avoiding drag risks due to excessively high levels of salinity and minimising the amount of purge required and
related costs.
The system consists of an on-line kit connected to a specific connection in the generator, just below the water level. It works by
opening the drain valve at regular intervals so that a precise amount of water reaches the conductivity probe located inside the
measuring chamber placed in line with the drain valve. The probe measures the electrical conductivity of the generator water,
whose value is related to the concentration of dissolved salts. The detected value is compared with that set in the regulator. If
lower, the valve closes at the end of the drain time. If higher, the system continues to repeat the draining cycle until the measured
value returns within the limits.
Salinity Control Unit (TDS Pneumatic)
The TDS control system limits the level of salts and minerals dissolved in the generator water within the value allowed by the
manufacturer, thus avoiding drag risks due to excessively high levels of salinity and minimising the amount of purge required and
related costs.
The system continuously measures, just below the evaporation surface, the electrical conductivity of the generator water whose
value is related to the concentration of dissolved salts. The detected value is compared with the set value. If it is higher, the purge
valve opens until the value returns below the setpoint.
"BNX" - "BBNX" Automatic purging unit
The automatic bottom drain unit avoids unnecessary repetitions or purge omissions that occur with the manual system. This
system allows for the sludge accumulated on the bottom of the generator to be regularly evacuated automatically through
the cyclical opening of the purge valve. The frequency and duration of the purges must be set by the user according to the
characteristics of the generator water as indicated in the technical manual of the generator.
The system requires compressed air.
GSS 72/1 72h global safety system for ≤ BX 600, ≤ BNX 1000, ≤ SIXEN 2000 and GSX ≤ 2000 generators
GSS 72/1 global safety system, designed and built to guarantee total safety of operation of steam generators.
The supply of the 72 hour exemption system without continuous supervision offered by
ICI CALDAIE S.p.A.
is provided with B+F
certification form, which implies testing the assembly, during construction or use, in the presence of the appointed Notified Body.
At start-up, a verification report is officially completed and stamped to allow the immediate commissioning of the assembly itself,
without waiting for the competent Authorities to certify the safety of the system, with the timing of the case. The user remains
responsible for complying with the provisions of M.D. 329/2004 regarding commissioning (COMMISSIONING REPORT).
Applicable on steam generators (BX 60÷600)-(BNX 100÷1000)-(SIXEN 350÷2000)-(GSX 350÷2000).

ATTENTION
The GSS 72/1 system can only be applied to boilers with boiling pressure of 12 bar or less.
GSS 72/2X global safety system
GSS 72/2X global safety system, designed and built to guarantee total safety of operation of steam generators.

High level safety kit
Kit designed to prevent an excessive increase of water level inside the boiler.
Once the set level is reached, the system stops the supply pump and triggers an acoustic alarm.
Alarm resetting and pump restart automatically occur once normal level in the boiler is restored.
