Spiral evaporator
The spiral evaporator perfectly copes with the technological task of transferring liquid to a vapor state. It is used in technological processes of gas, metallurgical, petrochemical and other industries.
Description and design
The heat exchanger consists of heat exchanger sheets twisted into a spiral and placed in a housing. The sheets are welded on one side to the central manifold, and on the other to the cylindrical body. The pins between the sheets help to form channels of constant cross-section. The body can be all-welded, or have removable covers for the possibility of mechanical cleaning of the heat exchanger channels.
