What is a Limpet Coiled Pressure Vessel?
A limpet coil vessel is a pressure-rated tank fitted with an external half-pipe coil (limpet) for heating or cooling the product inside. The limpet coil carries a utility fluid (such as steam, hot oil, or chilled water) to transfer heat efficiently without direct contact with the product.
