Description
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.
