Description
Synthetic flushing composition TERMOCLEAN® PRO has a high solvent capacity with respect to hydrocarbon components that are part of most petroleum heat transfer fluid oils, as well as synthetic organic high-temperature heat transfer fluids. THERMOCLEAN® PRO flushing composition has a very low viscosity and low pour point, a relatively high boiling point and temperature stability, which makes it ideal for adding to mineral and synthetic heat carriers, especially if they have already been subjected to thermal decomposition or oxidation (coking); in this case, the flushing composition THERMOCLIN® PRO will dissolve any hydrocarbon oligomeric sludge and sediment formed during the operation of heat exchange systems.
High solvent capacity of the THERMOCLEAN® PRO flushing composition allows it to effectively cope with the task even when adding only 5% to the volume of the heat transfer fluid.
Pre-cleaning of the system during the working cycle before draining the heat transfer fluid reduces the time of forced downtime of equipment and cleaning performed after draining the heat transfer fluid.
In most cases, flushing and mechanical cleaning of the system after draining the heat transfer fluid is not required, which reduces waste disposal costs and equipment downtime.
It reduces viscosity, which increases the efficiency of heat exchange and ensures a complete drain of the heat transfer fluid when it is replaced.
The dissolution of decomposed hydrocarbons makes it possible to increase the service life of the heat transfer fluid before the planned replacement.
Application areas
The THERMOCLEAN® PRO flushing composition is used in various industrial processes for heating or cooling with an intermediate heat transfer fluid, in which the low viscosity and high solvent capacity of the additive are very important for pre-cleaning the heat exchange system in the intervals between heat transfer fluid replacements or for extending the service life of the heat transfer fluid. The additive is particularly effective as a solvent in systems where hydrocarbon oligomeric sludge and sediment (coke) subjected to temperature decomposition or oxidation are present. For all applications of the THERMOCLEAN® PRO flushing composition in all the above conditions allows you to reduce the costs associated with troubleshooting.
Features of operation
With a low percentage of the flushing composition THERMOCLIN® PRO, it has a negligible effect on the steam pressure in the heat exchange system. If the boiling point of the heat transfer fluid is higher than the boiling point of the THERMOCLEAN® PRO additive (275°C), it is recommended to increase the pressure of the inert gas cushion to maintain the liquid state of the THERMOCLEAN® PRO additive and prevent the release of vapors through the exhaust valves of the expansion tank. THERMOCLEAN® PRO additive must remain in a liquid state in the heat exchange system.
THERMOCLEAN® PRO flushing composition is highly resistant to thermal stress and improves the overall thermal stability of most oil and liquid heat transfer fluids. The positive effect depends on the added volume of the additive.
To capture solid particles already present in the system, as well as any slowly dissolving new substances at the initial stage of application of the THERMOCLEAN® PRO additive it is usually necessary to use strainers on the pumps of the cleaning system and bypass filters. THERMOCLEAN® PRO flushing composition does not form a viscous or solid sediment that could be deposited on the surface of heat exchangers or clog the heat transfer fluid circuit. The additive helps to cope with these problems, however, not all the coke dissolves during the addition of the flushing composition. Part of the coke is washed off the walls of the pipelines and captured by mesh filters.
Compatibility of materials
THERMOCLEAN® PRO flushing composition does not cause corrosion of metals, which are usually used in heat exchange systems. For flange connections made without welding, seals of the IT-0 type or of fluorinated elastomers can be used at a moderate temperature range (230°C). At higher thermal loads and, in particular, at large temperature differences during the working cycle, high-strength graphite seals with metal inserts are successfully used to ensure the tightness of the heat exchange system. To select the optimal sealing material, follow the manufacturer’s recommendations.

Safety during operation and disposal
In sealed steel containers, the shelf life of the THERMOCLEAN® PRO flushing composition is 5 years. No special precautions are required during storage. When filling heat exchange systems from barrels or transporting in bulk, as well as during maintenance of heat exchange systems, the usual precautions are applied to avoid contact of oil with the body.
Do not allow oil to get into the soil or sewer system. The high flash point guarantees minimal risk of fire. Do not allow contact of THERMOCLEAN® PRO additive with an open flame; use foam and dry reagents to extinguish the fire.
