Armcoltherm 670 (-23℃~350℃) heat transfer oil
Armcoltherm 670 is a synthetic heat transfer fluid engineered for high-performance operation, exceptional thermal stability, low-vapor-pressure service, and stringent purity requirements.
Functions：
- Heat transfer: Facilitates thermal oil system transfer between system components—for example, from a heat source to a heat exchanger or process equipment.
- Cooling: Provides reliable temperature control in applications where aqueous coolants are unsuitable (e.g., due to high-temperature operation, corrosion sensitivity, or immiscibility concerns).
- Lubrication: synthetic heat transfer oil exhibit auxiliary lubricating properties, reduce friction and wear on rotating or sliding mechanical components.
