Features & Benefits
- Ready-to-Use Product Features
- Advantages
- Works at temperatures up to 80 °C
- Is suitable for formic, citric and amidosulfonic acid
- Contains a combination of specifically acting inhibitors and special surfactants with a high wetting effect.
- By reducing the interfacial tension, rapid wetting of the surfaces to be cleaned is ensured
- Does not affect the dissolution of scale as well as rolling and annealing scale
- Ensures uniform distribution in the acid as well as rapid wetting of the surfaces to be cleaned.
- Through the combination of specifically acting inhibitors and special surfactants with high wetting effect.
- Advantages of LITHSOLVENT Cleaning Concentrates
LITHSOLVENT cleaners are especially developed for acidic cleaning. These are ready-to-use mixtures of acid and inhibitor, ideally suited for a temperature range from room temperature to 80 °C.
LITHSOLVENT cleaners are intended for customers who do not have the option to prepare their own cleaning solutions. Generally, they are inhibited methanesulfonic, formic, hydrochloric, amidosulfonic, citric and phosphoric acids, formulated for different cleaning temperatures and materials.
- Product Highlights
The highly effective inhibitor formulation is used to protect all common iron and copper based metallic materials during chemical cleaning with hydrofluoric acid and its mixtures with organic acids as well as acid salts of EDTA (ethylenediaminetetraacetic acid) at temperatures up to 80 °C.

- Applications
- LITHSOLVENT 803 is a highly efficient inhibitor formulation for the protection of metallic materials during the chemical cleaning with hydrofluoric acid and its mixtures with organic acids as well as acid salts of the EDTA (ethylenediamine tetraacetic acid) at temperatures up to 80°C.
- LITHSOLVENT 803 contains a combination of specifically acting inhibitors and specific surfactants with high wetting properties. Consequently a uniform distribution in the acid as well as a quick wetting of the surfaces to be cleaned is ensured.
- LITHSOLVENT 803 inhibits the corrosion of all metallic materials which are present in the boiler and apparatus construction on the basis of iron and copper. The maximum working temperature is 80°C.
- The dissolution of scales and incrustations is not affected by LITHSOLVENT 803.
- Addition and Dosing
- In general the dosing rate amounts to 2 kg LITHSOLVENT 803 per m³ cleaning solution the concentration of which in general varies from 30 to 100g/l acid.
- For postpicklings with citric acid we recommend a product concentration of 2 kg LITHSOLVENT 803 per m3 cleaning solution.
- It is recommended to prepare the cleaning solution in a separate preparation tank and then to fill it into the system. Always dilute the acid at first and then add LITHSOLVENT 803.
- Due to the lack of storage stability of LITHSOLVENT 803 in concentrated acids, the product is not appropriate for the preparation of inhibited parent acids.
- The duration of action of the inhibited acid on the materials should not essentially exceed 6 hours.
- After cleaning the apparatus and equipment must be thoroughly rinsed with water.
- Areas of Application
Evaporators, steam boilers, heat exchangers, piping systems and all kinds of heat engineering equipment.
- Coverings
Inorganic scale such as calcium carbonate, calcium oxalate, silicates, occasionally phosphates, aconates, citrates, depending on water use, also sulfates or organic coatings.
- Examples / Best Practice
Free of quaternary ammonium compounds (QAV).
- Protection Applications
Depending on the acid and material LITHSOLVENT 803 offers appropriate inhibitors for effective protection of your plant.
