Open the catalog to page 23 The widest range Alfa Laval’s shell and tube production includes a wide range of condensers and desuperheaters with 8 different series providing individual solutions for each conditioning, refrigeration and cooling application. Standard models fulfil condensation capacities ranging from 3 to 900 kW and 1680 kW can easily be reached with the extension of the new CDEW series. The different condenser series have been carefully optimised for the most used HFC refrigerants. All condenser models can be opened for inspection and maintenance purposes. CFC, CRS, CPLUS, ACFL and CDEW series are...

Open the catalog to page 56 NOMINAL DATA Highest level in component design and manufacturing quality Models designed for fresh water applications (series CFC, CRS, ACFL, CPLUS and CDEW) use the following components: • Shell: carbon steel • Tube sheets: carbon steel • Tubes: integrally finned thick wall copper tubing • Covers: carbon steel • Gasket: thermopolymer compound • Baffles: teflon All the carbon steel components are sand blasted, including the internal wall of the shell. The precise fit of the tube exchanger baffle eliminates the risk of copper filings collecting. Models belonging to series CFC, CRS and ACFL...
Open the catalog to page 67 Versions 2 passes (Cooling tower water) 2 condenser series are dedicated to sea water, for on board marine applications and for all the other installations where it is possible to use the sea as a natural source of cooling water. Standard capacities range from 7 to 900 kW. Marine models are equipped with the following components: • Shell: carbon steel • Tube sheets: AISI 316 stainless steel • Tubes: integrally finned Cu/Ni tubing • Covers: AISI 316 stainless steel • Gasket: thermopolymer compound • Baffles: carbon steel Marine units are provided with interchangeable anodes made of soft...
