## Summary description

Šomis heating system antifreeze is a specialized heat transfer fluid designed to protect residential and industrial heating systems from freezing and corrosion. This 10-liter container provides reliable performance down to -20°C, ensuring efficient heat circulation and preventing damage to pipes and boilers. It is suitable for various closed-loop heating installations, offering long-term protection and system stability.

## Long description

Šomis heating system antifreeze is a professional-grade heat transfer fluid engineered to maintain the integrity and efficiency of residential and industrial heating installations. This 10-liter solution is specifically formulated to prevent freezing in closed-loop systems, protecting critical components such as boilers, radiators, and piping from damage caused by low temperatures. By providing a stable freezing point of -20°C, it ensures consistent thermal conductivity and reliable operation throughout the colder months.
Advantages
The primary benefit of using Šomis antifreeze is its dual-action formula that provides both frost protection and corrosion inhibition. By preventing the buildup of rust and scale within the system, it helps extend the service life of heating equipment and maintains optimal heat transfer efficiency. The fluid is designed for stability, ensuring that it does not degrade prematurely under standard operating conditions, which reduces the need for frequent system flushing and maintenance. Its reliable performance in closed-loop circuits makes it a dependable choice for maintaining system pressure and preventing blockages.
Suitable for
Closed-loop residential heating systems
Industrial heating and cooling installations
Boiler protection in seasonal properties
Radiator-based central heating networks
When it may not be suitable
This product is not intended for use in open-vented heating systems where the fluid may come into contact with the atmosphere, as this can lead to evaporation and degradation of the corrosion inhibitors. It is also not suitable for systems requiring a higher freezing point protection than -20°C or for use in potable water supply lines.
Key specifications
Volume: 10 liters
Freezing point: -20°C
Application: Closed-loop heating systems
Form: Concentrate
Weight: 10 kg
How to use
Before adding the antifreeze, ensure the heating system is completely drained and flushed to remove any existing debris or incompatible fluids. Dilute the concentrate according to the manufacturer's specific requirements for your system's total volume to achieve the desired protection level. Once mixed, fill the system slowly to avoid air pockets, and bleed all radiators to ensure proper circulation. After filling, check the system pressure and monitor for any leaks at joints or valves.
What to consider before purchase
Verify the total capacity of your heating system to ensure you purchase sufficient volume.
Check if your system is a closed-loop type, as this product is not compatible with open systems.
Ensure that the -20°C protection level is sufficient for the climate conditions in your region.
Confirm compatibility with the materials used in your pipes and boiler seals.
Usage recommendations: It is recommended to test the concentration of the fluid annually using a refractometer to ensure the freezing point remains within the safe range. Always wear protective gloves and eyewear when handling chemical fluids to prevent skin or eye irritation.
