You want to brew with classic brewhouse vessels and you do not want to use a steam generator? 

This can be the answer.

​

The OILBREW is an interesting brew design for brewers who want to brew with a classic brewhouse.

​

The use of hot oil offers several advantages over steam: It’s simple and far less expensive.

 

Food grade heat transfer oil is heated up in a reservoir with electric heaters and pumped through the huge jackets oft the vessel. The temperature control of the reservoir keeps the oil the whole time between 180 – 200 °C. During heating the oil temperature typically drops to around 150 - 170 °C. The heating of the vessel is stopped when the oil pump is turned OFF. The oil then flows back into the reservoir immediately to prevent temperature overswings. An OILBREW can be used as a single vessel or even integrated in an automated brewhouse. It can for example also be combined to a 3-vessel brewhouse with

 

• a lauter tun and another oil heated vessel that acts as the boiler/WP;

• a (modified) BREWTOWER whereas the upper vessel is the lauter tun and the lower vessel is the boiler/WP.

• ...

 

The advantage of the BREWTOWER design ist the very high heat transfer eficiency since the electric heaters are directly in the wort. This is why the BREWTOWERS need less power per liter.

 

Every indirect heating leads to losses. This is also the case when steam, hot water or oil is used to transfer the heat.

 

You can see in the spreadsheet below the typical powers needed for indirect heating with steam. Oil and steam are very similar here regarding the required power. This means the spreadsheet is also valid for the OILBREW. As mentioned above the power needed is higher than with a BREWTOWER due to the losses of indirect heating.

 

The charts below show the heating of an OILBREW600 with 30 kW and 45 kW. 450 liters of water and 600 liters of water are heated up. Compare the values in the spreadsheet. Even with "only" 30 kW normal mashing and heating up during lautering is still possible. The max. power of the OB600 would be 60 kW if enough electric power is available. 4 x 15 kW electric heaters would then be active.

 

The oil jacket of the OB600 has a volume of around 20 liters. The total oil volume in the reservoir is 70 liters. In fact a rather small amount of oil is needed for the heating.
