Product description
Modern multifunctional heat transfer fluid designed for heating and cooling systems. The product is supplied ready to use and does not require additional dilution. Its base is ethylene glycol and demineralised water, enriched with a package of corrosion inhibitors and biocidal additives that ensure durability and stable system operation.

Using ELVI Termofit guarantees reliable protection of equipment against freezing even under extremely low temperatures (–20 °C, –25 °C or –35 °C depending on the grade), as well as prevention of scale formation, bacterial growth, and corrosion processes.
The product is compatible with the main materials used in engineering networks: copper, aluminium, brass, and steel, making it a universal solution for most heating and cooling installations.

ELVI Termofit is equally suitable for industrial facilities requiring high reliability and long service life, as well as for individual heating systems in private houses. The use of this heat transfer fluid extends the service life of equipment and reduces the risk of malfunctions, ensuring stable and efficient system operation throughout the entire heating season.
System preparation
Before filling the system with the heat transfer fluid, preparatory work must be carried out. First, ensure that the system is leak-tight and cleaned from scale, corrosion deposits, and residues of old fluids. For this purpose, it is recommended to flush the circuit with water or a special cleaning solution. A clean system allows the heat transfer fluid to work at maximum efficiency and extends its service life.

Before use, ELVI Termofit should be mixed to ensure even distribution of all active components. The system must be filled slowly, monitoring the level and avoiding the formation of air pockets. After filling, it is recommended to start circulation and make sure the liquid is evenly distributed throughout the system.
Application
ELVI Termofit is completely ready for use and does not require dilution. The product is intended exclusively for closed heating and cooling systems, where constant pressure is maintained and there is no direct contact with atmospheric air.

Filling the system should be carried out at a temperature not lower than +5 °C. After filling, it is recommended to check the pressure, the tightness of connections, and to remove any possible air pockets.

The service life of the heat transfer fluid in a closed system is up to 5 years. After this period, the fluid should be replaced, even if it has not changed in appearance, as the additives gradually lose their active properties. During long-term operation, it is recommended to periodically check the condition of the fluid — its clarity, pH level, and absence of mechanical impurities.

The use of ELVI Termofit helps to increase the energy efficiency of the system, reduce the risk of failures, and ensure reliable equipment protection throughout the entire service life of the product.
Disposal
Hardened material and empty packaging should be disposed of as household waste.
