Kierrelevyjähdyttimiä

Kierrelevyjähdyttimiä, also known as spiral plate heat exchangers, are a type of heat exchanger designed for efficient heat transfer between two fluids. They consist of two concentric spiral channels, one for each fluid. The fluids flow in opposite directions within these channels, creating a counter-current flow pattern that maximizes temperature difference and heat transfer efficiency.

The design of a kierrelevyjähdytin offers several advantages. Its compact size makes it suitable for applications with limited space. The self-cleaning effect due to the spiral flow path helps to prevent fouling and reduces maintenance requirements, particularly when handling fluids with suspended solids or viscous substances. The smooth, continuous flow within the spiral channels also minimizes pressure drop compared to some other heat exchanger designs.

Kierrelevyjähdyttimiä are commonly used in various industries, including chemical processing, food and beverage production, and wastewater treatment. They are effective for heating, cooling, condensing, and evaporating applications. Materials used in their construction can vary depending on the corrosive properties of the fluids being handled, with stainless steel and titanium being common choices. The welded construction provides a leak-tight unit, ensuring safe operation.
