About Globaltherm® C1 FF

Globaltherm® C1 FF is a synthetic clean and flush product specifically designed to optimise the maintenance of heat transfer systems. This product is ideal for preparing new systems for their initial fluid fill or cleaning and flushing systems containing oxidised, degraded or contaminated fluids.

By effectively removing deposits that can foul system interiors, Globaltherm® C1 FF ensures your heat transfer system operates efficiently and reliably.

With its synthetic hydrocarbon formulation, Globaltherm® C1 FF features a high flash point and high initial boiling point, ensuring safety and reliability when cleaning high-temperature systems.

Suitable for systems using synthetic heat transfer fluids in liquid phase, Globaltherm® C1 FF provides an advanced, safe and efficient alternative to non-synthetic cleaning and flushing products, helping operators minimise downtime and maintain peak performance.

 

Why choose Globaltherm® C1 FF

Traditionally, manufacturers required two separate products for the cleaning and flushing process, which led to downtime lasting twice as long. Firstly  using a cleaner that is usually detergent based and is left in a system for a period of several weeks. The second process and product is a flushing oil to flush out the dirt removed by the cleaner.

Globaltherm® C1 HF is a dual-use product that can be used in applications operating from 5°C to 338°C. It is specially formulated to help remove harsh by-products of synthetic and mineral based fluids.

This is beneficial because it ensures best performance and optimum efficiency of a recharged system.

Global Heat Transfer also recommends cleaning and flushing brand new systems before the first fill to purge the pipes of any residual materials that have settled during the construction process.

• Safer to use: The synthetic hydrocarbon composition of Globaltherm® C1 FF offers a high flash point and high initial boiling point, ensuring greater safety when cleaning high-temperature systems

• Highly effective: Designed to dissolve deposits caused by degraded or contaminated fluids, Globaltherm® C1 FF provides a thorough clean to optimise system performance and prepare it for new fluid fills

• Timesaving: Cleaning your system with Globaltherm® C1 FF is faster than traditional chemical cleaning methods, reducing downtime and ensuring your operations resume more quickly

• Cost-efficient: By eliminating the need for expensive chemical cleaning, Globaltherm® C1 FF offers a more affordable solution for maintaining and restoring your heat transfer system

• Compatible and reliable: Fully miscible with most organic heat transfer fluids, Globaltherm® C1 FF integrates seamlessly into your system, simplifying the cleaning process

About Globaltherm® C1 HF

Globaltherm® C1 HF is a system cleaner and flushing fluid that helps to rid heat transfer systems of potentially harmful contaminants, such as oxidised residual fluids, carbon deposits, loose debris, water and volatile light ends.

Like Globaltherm® C1, it displaces and flushes out waste, leaving behind a cleaner and safer system that is ready to be filled with a new charge of heat transfer fluid. Globaltherm® C1 HF offers a higher flashpoint than all other cleaning and flushing fluids on the market, meaning that the flashpoint of the newly filled system remains the same.

Despite being non-invasive, it is impossible to remove 100 per cent of the cleaning fluid when draining. This means that, when filling the system with new heat transfer fluid, the flashpoint will be reduced instantly because of the lower flashpoint of the cleaning fluid.

How to use Globaltherm® C1 HF

Traditionally, manufacturers required two separate products for the cleaning and flushing process, which led to downtime lasting twice as long. Firstly  using a cleaner that is usually detergent based and is left in a system for a period of several weeks. The second process and product is a flushing oil to flush out the dirt removed by the cleaner.

Globaltherm® C1 HF is a dual-use product that can be used in applications operating from 5°C to 338°C. It is specially formulated to help remove harsh by-products of synthetic and mineral based fluids.

This is beneficial because it ensures best performance and optimum efficiency of a recharged system.

If the heat transfer system and internal fluid cannot maintain the required operating temperature of the process, the fluid may have degraded and may need replacing. Engineers might notice this if they are frequently turning up the temperature, but the flow rates have dropped off.

You should always take a representative sample of the fluid to find out the current condition. Thermal fluid sample data may show a high Total Acid Number (TAN) and carbon residue data. The test results may also indicate likely levels of internal system fouling along with viscosity and Particulate Quantity results.

Once the contaminated fluid is removed, you should refill the system with the cleaning fluid. You should circulate the fluid in the system at 108 to 122 degrees Celsius (225 to 250 degrees Fahrenheit).

The detergent additives are activated at this temperature and the cleaning fluid mixes with suspended loose particles and also removes any soft or intermediate insoluble carbon from the inside of the system. These particles will leave the system when you drain the cleaning fluid.

Depending on the condition of the cleaning fluid as it leaves the system, you can refill the system with more cleaning fluid or introduce the new heat transfer fluid. This is determined by an analysis of the levels of carbon and particles in the heat transfer fluid.

New systems are particularly at risk of contamination because of environmental exposure during construction. This exposure provides contaminants, such as water, soil, welding slag and finely divided ferrous material with an opportunity to get into the system and accelerate the thermal degradation process.

Contaminants can also damage other parts of the system, including pumps and seals, so it's essential that contaminants are removed before the virgin heat transfer fluid is added and the system goes live.

All systems should be flushed and cleaned before fresh heat transfer fluid is introduced. This is extremely important as any welding slag, ferrous material or yellow metals which have not been removed during manufacture could effectively catalyse the oxidation of the heat transfer fluid and in turn, accelerate the ageing of the fluid. Water could also be present in the system after building and will contaminate the new fluid if not removed before the new fill is introduced.
