One Product Series, Many Applications

The water cooled shell and tube condensers from PENEX have been a standard in refrigeration and air conditioning technology for 15 years due to their well-known reliability and performance. The PHCD series consists of two designs and thus meets the requirements of a wide variety of applications. The unique brazing process between tubes and tube sheets ensures excellent vibration stability and high safety in terms of tight-ness.

Standard Design For Normal Water

The heat exchanger tubes are characterised by high material thickness; This series is suitable for all types of coolants that do not attack copper.

  • 1 The performance data are based on: Refrigerant: R407c
  • 2 Pass
  • Refrigerant inlet temperature: 90°C
  • Fouling factor on the refrigerant side: 0.00004 m2K/W
  • Standard design
  • Condensing temperature: 40°C
  • Coolant inlet temperature: 29°C
  • Seawater resistant design
  • Condensing temperature: 35°C
  • Coolant inlet temperature: 25°C
