SINTEC heat transfer fluid THERMAGENT-30 ECO




 

High-quality environmentally safe heat transfer fluid of premium class « Thermagent- 30 ECO»is designed for different
types of heating and air-conditioning systems as a process fluid providing the operation at the range from -30°. to +106°
and primarily for double-pressure boilers and at sites with  advanced requirements to the environmental safety. Ingredients:
high-quality pharmacological propylene glycol, demineralized water, non-toxic organic (carboxylated) corrosion
inhibitors of new generation, due. 
 
Heat transfer fluids «Thermagent» have a lot of advantages over the coolants available in the market: 
- New generation of heat transfer fluids
- Organic Acid technology 
- Raw materials and components of leading chemical German companies. 
- Organic corrosion inhibitors do not contain borax, nitrites and amines 
- Environmentally safe. 
 
Recommendation of use: 
Safe heat transfer fluid «THERMAGENT-30 ECO» is produced on the base of 
pharmacological propylene glycol DOW (Germany) and is designed by the newest 
technology «Organic Acid technology». Contains non-toxic organic (carboxylated) corrosion 
inhibitors and the package of special additives made in Germany. 
It is designed for different types of heating and air-conditioning systems as a process fluid 
providing the operation at the range from -30°. to +106°. (according to instructions on the 
rules of operation of the equipment), and primarily for double-pressure boilers and at sites 
with advanced requirements to the environmental safety. Recommended to be used in 
refrigerating equipment of food, radio technical, electrical and other sectors of industry. 
 
 
«THERMAGENT-30 ECO» is not recommended to be used in the electrolysis boilers 
("Galan" type). 
Specially selected package of additives of heat transfer fluid protects from scale, corrosion 
and foaming. As an exception, it is undesirable to use it in systems with galvanized pipes, as 
precipitations are possible. «THERMAGENT-30 ECO» does not aggressively affect on the 
plastic and metal-filled plastic, rubber, paronite, and flax, i.e. exclude the possibility of leaks. 
However, it should be known that it has a little more fluidity than water, so much care should 
be taken when assembling all seal assemblies and preliminary system pressure testing 
should be obligingly carried out. 
If necessary, the joints in the systems can be treated with a sealant resistant to glycol 
mixtures ("Hermes», «ABRO», «LOCTITE»), as well as use silky line without first coating 
with oil paint. 
Heat transfer fluid has high stability and ensures continuous operation for ten years. 
It is not recommended to dilute «THERMAGENT-30 ECO» with water as it can lead to 
deterioration of corrosion properties. 
 
 
Attention: mixing with other heat transfer fluids and antifreezes without preliminary check is 
 
undesirable because it can lead to the destruction of anti-corrosion additives and 
deterioration of anticorrosion properties. 
 
 
Lifetime of heat transfer fluid depends on the mode of its operation. It is not recommended to 
bring heat transfer fluid to the state of as in case of overheating to temperatures more than 
+170 ° C, high-temperature deterioration of ethylene glycol and additives will start. Therefore, 
heating boilers should be provided with adequate circulation of heat transfer fluid. 
To do this «THERMAGENT-30 ECO» should be diluted according to the recommendations 
specified in characteristics and have a more powerful circulation pump than at working on the 
water (on performance – in 10%, o pressure – in 60%), and also perform heating of heat 
transfer fluid at subzero temperatures gradually not turning on the boiler at full capacity. 
It should be also taken into account that heat transfer fluid has a higher coefficient of volume 
expansion in comparison with water; therefore expansion tank in the systems should be at 
least 15% of their volume. 
 
 
«THERMAGENT-30 ECO» is non-hazardous for human and animals, has the tolerance for 
using as a coolant in food industry. However, it does not mean that it can be drunk. 
Heat transfer fluid is flame- and explosion-proof, has certificates of conformity and Sanitary-
Epidemiological Conclusion Certificate.
