Thin area
Heineken takes all the required
precautions to minimise risks caused
by careless use. The wall of the kegs,
for instance, contains a thin area at
one point which is invisible to the
naked eye. The average pressure insi
de a keg is 2-5 bar. If the pressure
increases to 10 bar for whatever
reason, then that thin part of the wall
will rupture and allow the pressure to
escape.
The safety of the carbon dioxide
gas cylinder is guaranteed by the redu
cing valve. If that valve does not work,
a safety blow-off valve is triggered.
And, if that safety feature also fails to
operate properly, a fracture in the line
between the cylinder and the keg will
indicate that something is wrong.
Lastly: a dispenser installation
works using electricity. The specialist
fitter will always ensure that an earth
ed connection is used, because the
cooling system contains water. And
water and electricity together form a
lethal combination. Hans Schutt
stresses that the on premise pro
prietor should call in professional
help if modifications have to be made,
or to use his words: "When con
necting up a new keg, follow the inst
ructions to the letter. If a problem
occurs: let the expert solve it and
never try to repair faults yourself. If
you have even the slightest doubt
about the functioning of the dispenser
installation: don't take risks, get on
the phone!"
The correct way of securing a carbon
dioxide cylinder: chain it to the wall.
