Shell and tube condensers type SPR are designed to condensate HCFC, HFC and NH3 refrigerants in refrigeration and air conditioning plants, both marine and lands applications. Condensers can be supplied with approval of Marine Classification Societies: PRS, LRS, DNV-GL, BV, RMRS and with approval of notified body for land application (CE mark). The condensers are available in three versions: - Version with high capacity cupronickel (10%) tubes (W) which is design to condense HCFC and HFC refrigerants. This version can be cooled by seawater and freshwater. - Version with carbon steel tubes which is designed to condense NH3. This version can be cooled by freshwater - Version with titanium tubes which is designed to condense NH3. This version can be cooled by seawater and freshwater. * This is the heat exchange surface for version with high-performance cupronickel tubes (W). ** There is the possibility to order condenser with other cooling water inlet/outlet diameter
