Alfa Laval DOC (dedicated oil cooler) brazed plate heat exchangers provide the same efficient heat transfer and compact construction as our CB models, but with a design that is specifically engineered for oil cooling applications. With a reinforced flange connection that withstands high vibrations, DOC units can reliably handle heavy mechanical loads that accompany engine and hydraulic applications.

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.

With more than 80 years of experience in heat transfer innovation, Alfa Laval knows what it takes to deliver high-performance solutions for any application. Our experts continuously develop new innovations that give our DOC line of brazed plate heat exchangers more reliable and efficient performance.

PressureSecure

Unparalleled strength for demanding duties

Our innovative plate designs support the widest range of high-temperature and high-pressure applications. Units can run using thinner plates and fewer plates, which translates to less raw material, lower energy consumption, reduced refrigerant charge and a longer equipment lifecycle.

FlexFlow™

Superior thermal performance

Alfa Laval’s patented asymmetrical plate design is one of many unique innovations that gives you improved thermal efficiency thanks to optimized pressure drop and increased turbulence. In addition to cutting energy consumption, that means reducing refrigerant volumes and raw materials.
