Copper tubing and manifolds, high-performance aluminium fins, resistant to fouling.
anti-shear system for tube bundles.
pipings for drycooler: IsO pN16 type 02a rotating flanges in line with NFeN1092 in 304L stainless steel (1 or 2 input(s)/
outputs(s) depending on the flow rate) – the tubes are sealed with plastic caps to protect the bundle.
tubes for condenser: copper (1 input/output per refrigerating circuit for units with 1 fan line, 2 inputs/outputs for units with 2 fan
lines). Delivered pressurised with nitrogen.
