The new EcoFlex CDH heat-exchanger frame range features frame plates that have been considerably reduced in thickness. The cross section reduction in the clamping bolts has been compensated for by a greater number of bolts, which in turn leads to uniform pre-tensioning of the plate package. The frame concept is especially suitable in building utilities, where pressures up to 10 bars are normal and where the costly safety reserves necessary in other applications are not required. Two model sizes are available: NT 50 CDH and NT 100 CDH. The plates are made of stainless steel (AISI 316/1.4401), and the units are designed for temperatures up to 100°C. The plate heat exchangers are available in two support lengths (60 and 120 plates). — GEA PHE Systems, Sarstedt, Germany
