Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of oil coolers, it is recommended to prioritize checking key technical parameters such as heat exchange area and oil side pressure drop to ensure that they match the flow and temperature control requirements of the existing system.
  • In the application scenarios of the power or chemical industry, it is necessary to choose shell and tube or plate type oil coolers based on the characteristics of the cooling medium, and pay attention to the impact of anti-corrosion materials on equipment life.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information.
  • When purchasing oil coolers, it is usually necessary to pay attention to installation space limitations. It is recommended to measure the equipment size in advance and confirm the feasibility of the modular design scheme with the supplier.
