What Are Rotary Unions for Thermal Oil?

A thermal oil rotary union is a precision-engineered device that enables heat transfer oil (hot oil) to flow from a stationary pipeline into rotating equipment without leakage.

Core functions include:

  • Delivering thermal oil to heated rollers or cylinders
  • Maintaining consistent temperature across rotating surfaces
  • Preventing leakage in high-temperature environments
  • Supporting continuous industrial heating processes
