Chemical composition is an important factor to consider when selecting a heat transfer fluid. Chemical composition will have an impact on the fluid’s properties, such as thermal stability and heat transfer efficiency. Matching the fluid to the system and the operating temperature can help to preserve fluid life.

 

While mineral heat transfer oils offer a good trade off between cost and performance, synthetic heat transfer fluids are the more popular choice in pharmaceutical applications. These have a lower susceptibility to form carbon than mineral based oils, offer better heat transfer efficiency and thermal stability, as well as a higher resistance to fouling.

Global Heat Transfer has over 30 years of experience in supplying and maintaining thermal fluid for the pharmaceutical industry.

A range of Globaltherm^® heat transfer fluids can be used for pharmaceutical batch processing because of their broad operating temperature range.

Proactive analysis and maintenance of heat transfer fluid is essential for pharmaceutical manufacturers. Thermal fluids degrade over time, particularly at high temperatures, reducing the efficiency of the system.

Regular thermal fluid analysis helps plant managers monitor oil condition. By taking a sample when the heat transfer system is hot, closed and circulating, plant managers get an accurate representation of the condition of the fluid inside the system.

After taking an accurate sample, plant managers can send the sample to thermal fluid experts, such as Global Heat Transfer, for analysis.  Regular sampling can also act as an early warning system, allowing plant managers to intervene and solve issues before they impact production.

At Global Heat Transfer we provide an extensive preventative maintenance programme, Thermocare.

Our expert engineers will work with you to improve accuracy when monitoring fluid, provide technical interventions when necessary, organise maintenance schedules and train staff. Our team also offers 24 hour engineering support to help you quickly diagnose and fix faults that can impact production.
