?xml>The water-cooled pipe bundle condensers from BITZER have long represented a standard in the refrigeration and air conditioning technology due to their well-known reliability and performance. The K series consists of two different versions to meet the demands of a wide variety of different applications. The unique soldering process used to connect the pipes and pipe bases provides excellent stability against vibrations and secure seals.
New models
The new model K6703.(B) and K8503.() enhance condenser performance of the standard and salt water resistant versions in the range above 1000 kW.
Standard version for normal water
The heat transfer pipes stand out for their high strength, the pipe bases are plastic-coated. This series is suitable for all coolant types that do not react with copper.
Salt water resistant version
The K..B models have been tried and tested over many decades in all kinds of maritime applications. They are extremely resistant to sea water corrosion. The low fouling profile pipes as well the plastic coating on the pipe bases and cooling medium recirculation caps make this a top choice. Liquid refrigerants flow out through an immersion pipe outlet on models up to K813HB and through two refrigerant outlets on models K1053HB and above.
Pressurised gas heater
Sizes K1053H to K4803T can also be supplied in the standard version for normal water as a pressurised gas heater. The optional second refrigerant outlet must be ordered in this case.
Features
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 ...

Technical data
(see explanation 4)
Notes
- Performance data based on:
Refrigerant: R134a
2 pass cooling
Refrigerant inlet temperature: 90 °C
Cleanliness factor on cooling medium side: 0.00004 m²K/W
Standard version
Condensation temperature: 40 °C
Cooling medium inlet temperature: 29 °C
Salt water resistant version
Condensation temperature: 35 °C
Cooling medium inlet temperature: 25 °C
Condenser capacity is heavily influenced by the conditions in which the system is being operated. Performance data for other refrigerant and cooling media can be found in the BITZER SOFTWARE. - This performance data assumes a maximum flow speed of 2.0 m/s for the salt water resistant versions
- Fluid temperature of 20 °C and container filled to 90%
- Additional refrigerant outlet
