Slippurinn DNG has manufactured hot water/enzyme tubs for all major liver processing plants in Iceland.

Hot water/enzyme tubs are used to separate the membrane from the liver, as parasites can often hide between the membrane and the liver.

After passing through the trimming table, the liver is goes into the hot water/enzyme tub, where the membrane is loosened/separates from the liver.

A heat exchanger is connected to the tub to regulate the water temperature, which is typically maintained between 55-60°C.
