SOLAR FLUID FOR COLLECTORS SL

Solar fluid
Solar fluid

SL - ready-to-use liquid for solar collectors. Low-boiling propylene glycol solution with corrosion inhibitors for filling transport and heat exchange systems, cooling and heating devices, especially solar systems.

Description of the solar fluid

The fluids are an aqueous solution containing non-toxic pure propylene glycol, corrosion inhibitors and stabilizing additives. Manufactured in green color as standard. On request it is possible to produce the fluid in a different color. They are biodegradable, have significantly lower toxicity and are not subject to phase separation.

They protect systems from low temperatures, metal corrosion processes, deposits and the development of biological life. They are neutral to most plastics and seals used in systems and pumps.

The fluid provides effective corrosion protection for a period of at least 3 years. With the correct concentration of SL concentrate in the fluid, the service life can be significantly extended. The fluid is made from a concentrate that contains monopropylene glycol, corrosion inhibitors and stabilizing additives. Fluid losses in systems should only be replenished with SL fluids or concentrates.

SL - solar fluid - hygienically certified by PZH (Polish National Institute of Public Health).

The safety data sheet and the technical specifications of the product contain all the necessary information on the safe use of SL fluids and how to deal with malfunctions and spills. Used SL fluids can be disposed of in waste incineration plants or biological treatment plants in accordance with local legislation. SL fluids that are not classified as hazardous substances are not covered by the regulations: RID, ADR, ADNR.
