Application
Globaltherm® 55 is a synthetic heat transfer fluid designed for use in moderate temperature, non-pressurised or low pressure indirect heating systems.
The thermal fluid is designed to provide reliable, consistent heat transfer performance over a long time in a range of applications at recommended bulk temperatures of up to 300 °C (570 °F). Globaltherm® 55 is recommended for use in industrial applications such as asphalt (bitumen), biomass, cement, gas to liquid, oil & gas, production of bio alcohol and biodiesel, hot mix asphalt, natural gas purification, polymer and plastic and waste heat recovery.
About Globaltherm® 55
Globaltherm® 55 is a synthetic thermal fluid with excellent pumpability (-28 °C [-18.4 °F]), when compared to other heat transfer fluids, allowing the heat transfer system to start up quickly and easily.
- Globaltherm® 55 is used for applications operating from -28 °C (-18.4 °F) to 300 °C (570 °F). It’s broad temperature range means it can be used for both heating and cooling.
- Globaltherm® 55 can offer long life, reliable, cost-effective performance continuously at 300 °C (570 °F) if required by the application, meaning customers don’t need to over specify their fluids.
- The fluid is designed to be resistant to oxidation and help manufacturers to extend fluid lifespan.
