DOUBLE WALLED: A double walled skin filled with a thick layer of polyurethane foam
for insulation. This is what keeps the wort at a constant stable temperature that
does not get influenced by any outside environmental changes and provides
insulation for your fermentation that a standard jacket cannot achieve.
Integrated heating: In the cavity of the fermenter between the outer body and cone
sits a 30 Watt, 12V heating element. Unlike standard heating elements/sources
that directly heat liquid, this heat stick is designed to heat the environment in
between the walls of the fermenter, which in turn heats the liquid. It is similar to
controlling the temperature in a temperature controlled room. The fermenter acts
as an artificial environment which can be heated, meaning the temperature is
raised in an even and controlled manner which is much better for the yeast.
INTEGrated cooling sleeve: In between the two stainless steel walls sits a cooling
sleeve (also made of stainless steel). This cooling sleeve is welded onto the inner
wall of the fermenter and can be hooked up to the additionally purchased Glycol
Chiller. Temperature is dialled into the Temperature Controller and as the cooling
liquid travels through this sleeve, it cools the stainless steel which in turn cools
the beer in the fermenter. The cooling sleeve never comes into contact with the beer,
it is completely concealed and built into the fermenter and never needs cleaning
or sanitising - a true innovation for a fermenter of this scale.
Easy access to the interior for hassle free cleaning: The Grainfather Conical
Fermenter has a smooth interior with no additions such as cooling coils or
additional sampling valves meaning it is easy to clean and minimises the risk of
