It features smooth cross-flow spiral tubing, with an inner shell and baffle plate for optimal primary energy capture (D-HWT 35) or without an inner shell baffle plate (D-HWT 54), advanced welding technology and top quality processing. The longevity of the device is guaranteed thanks to the finishing of the material through staining, passivation and external electroplating. These heat exchangers offer maximum energy efficiency with minimum pressure loss. Like all spiral tube heat exchangers, they must be integrated directly into the pool water circuit or via the bypass system
