Description:
Master ECO™ coolants for heating and heat exchange based on propylene glycol are characterized by the following positive properties:
● are environmentally friendly and non-toxic;
● Master ECO™ trademarks can withstand high temperatures;
● reliably protect the heating system from freezing at low ambient temperatures in winter;
● have lubricating and bactericidal properties;
● have good thermophysical characteristics, thanks to which the room is heated evenly;
● fire and explosion proof;
● do not form scale.
● neon dyes are used, which help to more easily detect the leak in the event of a leak in the system (the need for such an additive is indicated when ordering)

User manual:
Before using Master ECO™ coolants, the heating system must be completely cleaned of waste liquid. You should also remove old deposits and scales from the circuit, eliminate corrosion traces, and ensure there are no zinc-containing parts.

The heating system is filled by gravity, either manually or under pressure. The manual filling is applicable for open circuits. Coolant is pumped into closed heating systems under pressure using pumps.

It is important to ensure a good seal, since aqueous propylene glycol solutions, having a high wetting effect, can leak where water does not flow. If it leaks, the efficiency of the entire heating system decreases. If they are detected, it is necessary to pause the entire system’s operation and eliminate the malfunction.
Procedure in case of emergency shutdown of the heating system.
Solutions of propylene and water at zero temperatures and below have a high level of viscosity. Therefore, if the system has cooled down, it is recommended to first turn on the heating elements themselves, and then start circulation. This will reduce the load on the pumps.

The service life of Master ECO™ coolants is at least 7 years. The price of the coolant depends on the concentration of the main base component. When ordering and purchasing it, it is necessary to consider the percentage of propylene glycol in the coolant brand. The temperature range in which the all-season low-freezing coolant will be in a working condition depends on this indicator.

Storage and transport conditions
Monoethylene glycol concentrate should be stored in closed original packaging in dry, unheated ventilated rooms. Expiry date – 60 months from the date of manufacture. The material can be transported in vehicles covered by any means of transport in accordance with the rules for the carriage of goods for this type of transport.

Medical, pharmaceutical and personal care applications
Glycerin is mildly antimicrobial and antiviral and is an FDA approved treatment for wounds. The Red Cross reports that an 85% solution of glycerin shows bactericidal and antiviral effects, and wounds treated with glycerin show reduced inflammation after roughly 2 hours. Due to this it is used widely in wound care products, including glycerin based hydrogel sheets for burns and other wound care. It is approved for all types of wound care except third degree burns, and is used to package donor skin used in skin grafts.

Antifreeze
Like ethylene glycol and propylene glycol, glycerol is a non-ionic kosmotrope that forms strong hydrogen bonds with water molecules, competing with water-water hydrogen bonds. This interaction disrupts the formation of ice. The minimum freezing point temperature is about −36 °F (−38 °C) corresponding to 70% glycerol in water.

Chemical intermediate
Glycerol is used to produce nitroglycerin, which is an essential ingredient of various explosives such as dynamite, gelignite, and propellants like cordite. Reliance on soap-making to supply co-product glycerol made it difficult to increase production to meet wartime demand.
