Brazed plate heat exchanger technology by Davhex
Inside the heat exchanger.
Production process, research and development, and quality control: skills Polidoro has built over more than 80 years in the OEM market.
A datasheet describes the performance of a heat exchanger. How it is designed and built determines how repeatable that performance is over time.
Davhex heat exchangers are made of corrugated AISI 316L or AISI 304 stainless steel plates, joined with Cu 99.9% copper sheets and brazed in vacuum furnaces. The process creates a hermetically sealed, gasket-free component with high heat transfer efficiency and pressure resistance.
Davhex technology rests on three elements: production process, applied research and the ability to develop solutions together with OEMs.
Vacuum brazing and materials
Stainless steel, copper and vacuum brazing: discover how the heart of a Davhex heat exchanger is made.
R&D and testing
Co-development, test rooms, life tests and CFD and FEM simulations to develop and validate new solutions.
Production and quality
Automatic presses, vacuum furnaces with rapid cooling, testing, and a dedicated line for samples and small batches.
