Calflo AF Heat Transfer Fluid – High Performance Thermal Transfer Fluid

Calflo AF Heat Transfer Fluid is a high-performance thermal transfer fluid designed for closed-loop, liquid-phase heating systems operating at high temperatures. Formulated for demanding industrial applications, it provides efficient heat transfer and strong resistance to oxidation, with a maximum stated bulk operating temperature of 316°C (600°F).

Manufactured from highly refined base oils with advanced additive technology, Calflo AF is designed to maintain thermal stability during continuous high-temperature operation. Its resistance to oxidation and deposit formation helps support longer fluid service life and reliable performance in industrial heat transfer systems.

High-Temperature Thermal Transfer Fluid

Calflo AF is designed for systems where conventional lubricating oils are not suitable for the required thermal transfer application. Its formulation allows it to circulate through a closed-loop heating system, transferring heat efficiently while resisting thermal and oxidative degradation.

The result is a thermal fluid designed to help maintain consistent system performance in demanding manufacturing and process-heating environments.

Suitable for Plastic Processing & Manufacturing

Heat transfer systems are widely used in manufacturing processes where accurate and consistent temperature control is important. Calflo AF can be used in suitable systems serving plastic processing, rubber manufacturing and other industrial production equipment.

Maintaining thermal stability at elevated temperatures can help reduce fluid degradation and the formation of unwanted deposits, supporting efficient heat transfer and system cleanliness.

Oxidation & Deposit Resistance

Heat transfer fluids are exposed to prolonged periods of elevated temperature, making resistance to oxidation and thermal degradation important characteristics.

Calflo AF is formulated to provide excellent oxidation resistance and thermal stability, helping minimise the formation of sludge and varnish that can affect heat transfer surfaces and system performance.

Keeping the thermal fluid in good condition can also help reduce maintenance requirements and support longer operating periods between fluid changes, subject to system conditions and regular fluid monitoring.

Equipment & System Applications

Calflo AF is recommended for suitable systems associated with equipment manufacturers including:

• Alfa Laval
• IDE
• Mokon
• Single Temperiertechnik
• Bran + Luebbe Metering
• Cincinnati Milacron
• Fulton
• Wanson
• Regloplas AG
• Watlow
• American Maplan
• Krauss-Maffei

Manufacturer names are provided as application references. Always confirm the specific equipment model and manufacturer's fluid requirements before use.

Operating Temperature

Calflo AF is designed for applications with a maximum stated bulk operating temperature of 316°C (600°F).

Actual operating conditions depend on system design, fluid condition, circulation, heater design and other factors. The equipment manufacturer's operating limits should always be followed.
