Calandrias and Brewing Equipment

What is a Calandria?

Calandrias are the key heating component in both nuclear power generation and in the process of brewing craft beer. In the brewhouse, a calandria is a heat exchanger which boils wort inside the brew kettle or heats water in the hot liquor tank (HLT). There are two common installation methods for calandria:

  • Internal: a submersed calandria heats the surrounding liquid
  • External: the liquid being heated is pumped through tubes with a high surface area to volume ratio

In both installations super-heated steam is the heating medium.

PKW Calandria Specifications

As with all our brewing equipment, Portland Kettle Works calandrias are designed and manufactured to exacting standards.

  • Our proprietary Convect-o-Matic Internal Calandria is integrated into both our brewhouses and our hot liquor tanks (HLT). These internal calandrias continually agitate the tank contents resulting in a consistent liquor temperature throughout the vessel without the use of expensive and maintenance-intensive pumps.
  • Our proprietary Valveless External Calandria (VEC) is included with our mash tuns and lauter tuns. These external calandrias precisely maintain mash temperatures without heat-stressing the grain bed.
