Bitzer K203HB 2P/4P  water-cooled condensing unit 

• Seawater-resistant implementation: connection male thread for refrigeration
• Suitable for standard refrigerants.
• Shell and Tube condenser with finned pipes, protective gas charge, entrance.
• Rotalock or soldering connection soldering connection, flange with fluid output.
• Rotalock valve with solder connection, K123HB.. K4803TB with second fluid output (ships), right angle mounting brackets above and below.

Bitzer K203HB is Suitable for all commonly used refrigerants (HFC, HFO, HFC/HFO blends) and including a version approved for use with hydrocarbons (propane, propylene), 

 K203HB  Bitzer condensers represent a standard and robust solution for seawater cooled applications. 

These condenser K203HB ensure excellent reliability thanks to the unique tube-brazing process and the coating of the tube sheets.

While the use of a low-fouling design for the exchange tubes means that the  K203HB condenser can deliver a consistent performance throughout its life.

The Bitzer Sea water cooled condensers have resistant design for seawater. They are proven over decades in all maritime applications. 

The condensers are extremely corrosion-resistant to seawater. The low fouling profile tubes and the coating of tube sheets and coolant reversing covers make them the first choice.
