The construction of these units does not include gaskets, making them ideal for applications where aggressive process media or other conditions could damage the gaskets that would be used traditionally in gasketed-plate heat exchangers. Internal, shock-proof contact points hold together the plate pack, without the need for external frame plates for design pressures up to 70 bar (1015 psi). The edge of the plates and the plate-plate contact surfaces are also fusion-bonded, reinforcing against internal media pressure.
AlfaNova units are subjective to exhaustive pressure, thermal and corrosion resistance tests, ensuring maximum safety, reliability, durability. The construction of these models allows for optimal heat recovery due to attaining close (2°F) temperature approaches.
