This U-tube bundle is engineered for hydrocracking stabilizer feed service, a duty that combines significant heat recovery with wide temperature differentials across the exchanger. The U-bend construction absorbs the differential expansion directly, removing the expansion joint and improving reliability in cyclic operation, while delivering the 2.11 MW class heat duty the service requires. Fabricated under ASME U Stamp with CE certification, the bundle is supplied as a dimensionally matched replacement for your existing unit. Full documentation, including thermal rating, material certificates and test reports, is provided with installation support.
