SOLAR FLUID CONCENTRATE
Solar fluid
Solar fluid
The SL concentrate and the SL liquid are aqueous solutions with practically non-toxic pure propylene glycol, corrosion inhibitors, stabilizing additives and green dye. The liquid can be supplied in a different color upon customer request.
Description of the solar fluid
The SL - solar fluid - concentrate protects the installation from low temperatures, metal corrosion, deposits of sediments and the development of biological life. It is neutral to most plastics and seals used in installations and pumps. It is biodegradable and has significantly reduced toxicity.
The concentrate is used to produce fluids that provide effective protection against corrosion for a period of at least 3 years. With the right concentration, the lifespan of the fluids can be greatly extended.
The concentrate contains approximately 93% pure propylene glycol and corrosion inhibitors and is used to prepare working solutions. The concentrate is diluted with deionized water. The loss of liquids in systems should only be compensated with SL liquid or SL concentrate.
It is recommended not to use less than 33% of the concentrate in the solution.
SL – solar fluid – concentrate - has a hygiene certificate from the PZH (Polish National Institute of Hygiene).
The data sheet and technical specifications of the product contain all necessary data regarding the safety of SL fluids and procedures in case of accident and fluid leakage. Used SL fluids can be disposed of in waste incineration plants or biological waste treatment plants according to local laws.
SL liquids are not classified as dangerous substances and are not covered by RID, ADR, ADNR regulations.
