Oeltechnik Shell & tube heat exchangers

Oeltechnik Shell & tube heat exchanger. OELTECHNIK has developed, tested and continuously improved its shell & tube product program in response to the challenges of the industry. The in-house developed software is based on recognized literature such as VDI Wärmeatlas and HEI. It has been checked against actual test performance of our equipment.

OELTECNIK has always taken challenges to explore further design options for shell & tube heat exchangers. Shell & tube heat exchangers are rated, designed and fabricated in-house and can be supplied according to individual customer’s specifications.

Design parameters

OELTECHNIK’s products are successfully in use worldwide. Our design and fabrication capabilities are covering all international design codes and national regulations.

Our type OK coolers are standardized from 100 mm (4”) to 400 mm (16”) in shell diameter. Typically, oil is on the shell side and water on the tube side. For every application the coolers are individually check-rated with our thermal rating programs. For higher flow rates custom tailored designs are prevailing. Certainly, the OK type shell & tube heat exchanger can be used for other liquid to liquid applications.

The type LK indicates that one fluid is gaseous or has major gas components. Together with our customer we decide whether the gaseous fluid is on shell or tube side. Factors like design pressure, desired nozzle location, aggressiveness of fluids, desired material combination, thermal performance and allowable pressure drop influence the decision about fluid location.

OELTECHNIK will assist you in making the most economical selection under consideration and evaluation of all parameters.
