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.
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.
