DIESTA Tubes
DESCRIPTION BENEFITS
DIESTA is an innovative new finned tube technology, dedicated to air cooled heat exchangers, using enhanced surfaces, that has the ability to improve plant efficiency and reduce construction costs without deviating from the robust design requirements of oil & gas industry standards such as API 661.
KEY APPLICATIONS
- LNG air-cooler fields including MR compressor inter- and
aftercoolers, C3 refrigerant coolers (desuperheater,
condenser and subcooler) - Ethylene quench-water air cooler fields
(focus naphtha-based crackers) - Other areas: gas processing plants, gas compression stations, refineries
- Available for greenfield and revamp debottlenecking projects
