Heat Transfer Fluid - is the basis of reliable operation of heating, ventilation and air conditioning industrial facilities,
shopping centers, and private homes. The most common types of heat transfer for the heating systems are water and aqueous solutions
of glycols and alcohols.
Water has a good thermal capacity and flow ability. But as a result of its application arises corrosion of metal parts of the heating system.
In the event of defrost water freezes and displays the entire system fails. At present, heating systems are widely used specially
designed antifreezes - antifreeze (ethylene glycol solutions of alcohol and propylene glycol with additives).
Antifreeze based on aqueous glycol contains mostly ethylene glycol 65%, 30% water and 5% of inhibitors (additives).
Inhibitor - a substance inhibiting chemical processes, such as corrosion of metals, polymerization, oxidation, scaling,
swelling and dissolution of the rubber seals, foam and many others. They do not allow the Heat Transfer Fluid in the range
of operating temperatures to boil and foam, to destroy the materials of construction and freezing to a temperature of -65 ...- 70 ° C.
Inhibitors make antifreeze chemically stable product.
For consumer convenience and ease of transportation antifreeze sold as a concentrate (95% ethylene) and in the already ready to use.
Buying concentrate, the consumer must know: "local" water used for dilution of the concentrate can give a reaction - precipitation.
What is unpleasant is precipitated inhibitors, necessary for normal functioning of antifreeze. Therefore, experts recommend to buy
a ready-to-use antifreeze or used to dilute the concentrate with distilled water.
The main drawback is the toxicity of ethylene glycol. After contact with this substance on the skin or in the human body is a chemical
poisoning. Harmful also its evaporation. A lethal dose of ethylene glycol in humans is 5 mg per 1 kg of body weight. Antifreeze on
glycol basis is not used associated with food systems, water supply and heating systems in the open (open expansion vessel) where Heat
Transfer Fluid evaporation is possible. The optimal coolant system for any antifreeze is propylene glycol. With all the necessary properties,
it is absolutely non-toxic and can be used in systems with high requirements for environmental friendliness.
AUTOHIM company offers customers Heat Transfer Fluid based on ethylene glycol and propylene glycol on its own original recipes.
Produced by antifreeze ensures a low freezing point, excellent corrosion protection system, scale, and many other problems.
The great interest in Latvian market is an eco-friendly Heat Transfer Fluid on the basis of alcohol complex, which has increased
capacity and fluidity and is ideal for use in heat pumps.
AUTOHIM company specialists provide advisory support, starting from dating to the project, selection of the characteristics of the Heat
Transfer Fluid based on customer requirements, delivery to the site and filling system.
The service life of Heat Transfer Fluid is 5-7 years of continuous operation, or 10 heating seasons.
For the convenience of its customers AUTOHIM company offers periodic (every 2 years) analysis of working Heat Transfer Fluid,
which allows to determine the status of anti-freeze and give recommendations for maintaining performance and time to identify and
correct problems in the heat exchange system.
