## Long description

Šomis heating system antifreeze is a professional-grade heat transfer fluid engineered for closed-loop heating and cooling installations. This 20-liter concentrate provides robust protection against freezing temperatures down to -40°C, ensuring that your heating system remains operational even in extreme winter conditions. By preventing the formation of ice and inhibiting internal corrosion, this fluid helps maintain the integrity of pipes, radiators, and boilers, ultimately extending the service life of your entire heating infrastructure.
Advantages
The primary benefit of using Šomis antifreeze is its exceptional thermal stability and protective properties. It is specifically formulated to prevent the buildup of rust and scale within metal components, which is essential for maintaining optimal heat transfer efficiency. Because it is a concentrated solution, it offers flexibility in dilution depending on your specific climate requirements. Its reliable performance in closed-loop systems ensures consistent circulation and prevents the costly damage associated with pipe bursts or system blockages caused by freezing.
Suitable for
Residential heating systems
Industrial heating and cooling installations
Closed-loop heat pump systems
Radiator-based heating networks
When it may not be suitable
This product is intended exclusively for closed-loop systems and should not be used in open-vented heating systems or systems containing materials incompatible with glycol-based fluids. It is not suitable for use in potable water systems or any application where the fluid might come into contact with drinking water.
Key specifications
Volume: 20 liters
Freezing point: -40°C
Type: Concentrated heat transfer fluid
Application: Closed-loop heating and cooling systems
Weight: 20 kg
How to use
Before adding the antifreeze, ensure the heating system is completely drained and flushed to remove any existing debris or old fluid. Dilute the concentrate with water according to the manufacturer's recommended ratios to achieve the desired level of frost protection. Once mixed, fill the system slowly to avoid air pockets, and perform a pressure test to ensure there are no leaks. It is recommended to use a refractometer or a similar testing tool to verify the concentration levels after filling.
What to consider before purchase
Verify the compatibility of your system materials with glycol-based antifreeze.
Calculate the total volume of your heating system to determine how many 20-liter containers are required.
Check local regulations regarding the disposal of used heat transfer fluids.
Usage recommendations
Regularly monitor the pH levels and concentration of the antifreeze in your system at least once a year to ensure continued protection against corrosion and freezing.
