Product Description
Thermaflo® A is a high-performance synthetic heat transfer fluid designed for both liquid and vapor phase systems as well as indirect heat transfer applications. It consists of a homogeneous mixture of diphenyl oxide and biphenyl, providing exceptional thermal stability and versatility for demanding industrial processes.
- Dual-Phase Capability: Operates in liquid phase from 12°C to 400°C (54°F to 750°F) and vapor phase from 257°C to 400°C (495°F to 750°F).
- Exceptional Thermal Stability: Delivers consistent, reliable performance across a wide temperature range.
- Low Viscosity: Ensures excellent heat transfer coefficients and efficient pumpability throughout the operating range.
- System Compatibility: Miscible and interchangeable with other similar high-temperature thermal fluids.
