tundish

The word tundish originates from a shallow wooden dish with an outlet channel, fitting into the bunghole of a tun or cask and forming a kind of funnel for filling it. These were originally used in brewing.
In general, any tundish will accept flow and store a small amount of material, while dispensing material elsewhere, similar to a funnel. In contrast to a funnel, the purpose is generally to regulate flow, and achieve a more steady output with intermittent inputs, and the tundish typically will take on a different shape.

    Hi, I have recently fitted a Telford Tempest Hot water cylinder, heated purely by 2 immersion heaters. I have fitted it with the required 'blow off' piping which includes a small Tundish. Obviously, the Tundish needs to be open to the air, rather than fully enclosed, but if you test the...
