Brew Tank Fill Tubes: (there will be one per group, the picture above shows a 2 group)
Heat exchangers exit on the left side of the steam tank and tubes (currently copper, were
stainless steel until serial number 352) deliver the water to the brew tanks.
Brew Tank:
Synesso’s™ brew tanks are entirely stainless steel, welded internally and externally to be
water tight and thermally stable. Each brew tank has its own temperature probe and element which
allows the user to set different temperatures on each group, as well as operate without a group if a
serious service issue arises. Attached to each group is a 3-way brew valve which controls the flow of
water from the group head to the brew chamber.
Brew Tank Drain Tube:
Each group head is fitted with a drain tube to easily drain the tank. Early machines use
a stainless steel tube with a ball valve attached. The first brew group drain was attached to the
drain manifold line. 2nd generation machines use a brass fitting with a copper seal. These are not
connected to the drain manifold.
Heating Element:
A 2-leg incoloy and stainless steel heating element which provides the heat for the steam
boiler. It is controlled by the thermal probes and will be shut off in the case of over-heating
or low water levels.
