CGT7111 – THERMOSIPHON SYSTEMS

For optimum and simple cleaning of the
vessel interior, a design variant is
available which can be dismantled
Modular design combination available
with a wide variety of system
components and instruments selection
possible, such as level switch,
circulation pump, hand refill pump,
thermometer, base frame etc.
Construction of the BFS 6000 is
designed for demanding operating
conditions up to 50 bar / 200°C
Optimum visual is achieved for level
monitoring through a robust design with
weld-pad type sight glass

The BFS system performs all the basic functions of a buffer/barrier system for the operation of double seals:
To pressurize the buffer chamber
Leakage compensation
Buffer/barrier fluid is circulated by thermosiphon effect
Or forced circulation system
To cool the seal
To selectively absorb product leakage and prevent dry
Running (tandem arrangement)
Use compressed air or nitrogen for pressurization; pressurization is monitored by a pressure switch.
The incorporated level switch issues a signal whenever the level of buffer/barrier fluid is too low.

Operating and installation diagram for a BFS6000 system
The BFS vessel must always be installed higher than the mechanical seal. The buffer/barrier fluid flows via the return pipe into the vessel and is cooled. The exchange of fluid takes place by the thermosiphon principle or by forced circulation, e.g. with a pumping screw. Connection pipes to the seal should be designed with as little resistance as possible.
