Bitzer  K1973T is Suitable for all commonly used refrigerants (HFC, HFO, HFC/HFO blends) and including a version approved for use with hydrocarbons (propane, propylene),
 K1973T Bitzer condensers represent a standard and robust solution for all normal and technical water cooled applications.
These condenser  K1973T 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  K1973T condenser can deliver a consistent performance throughout its life.

Maximum permitted pressure

• Refrigerant side: 33 bar / -10 to 120 °C
• Cooling medium side: 10 bar / -10 to 95 °C
  Temperatures below 4 °C require an antifreeze agent

This data applies for CE certification according to the EU Pressure Equipment Directive. Figures may vary depending on the certification process. Suitable for all conventional refrigerant and cooling media
