More with DOC

  • High connection load resistance for dependable, long-term performance
  • Small footprint combined improved efficiency reduce installation and long-term costs
  • Low-theta plate design and large ports ensure reduced pressure drop
  • Compact design increases flexibility for configuring, integrating, and installing a hydraulic oil cooling system with associated equipment
  • Available in eight sizes to match the widest range of capacity needs
The robust connection flanges on a DOC heat exchanger feature internal threading and integrated mounting brackets. Based on extensive application expertise, Alfa Laval has engineered this design to meet the tough operating conditions of oil cooling duties. In addition to allowing for significantly higher torque than conventional connections, the DOC units provide upfront savings thanks to easy installation with a compact design. And the reliability and efficiency over time will further ensure the lowest total cost of ownership for your system.
