Spiral Heat Exchanger

patented flat spiral heating coil | upto 18 in one layer

The patented flat spiral heating coil is used in storage tank type EHSF. Due to its flat design (height 12 cm) the heat exchanger is always located in the coldest area of the storage tank. This ensures a highly efficient heat transfer as well as a most hygiene hot water generation.  Because of the spiral shape design up to 18m² of heat exchanger surface can be placed in one layer.
