Solar Plants - Temper Technology

Heat recovery and Solar plants

ECO MPG is also suitable for closed secondary cooling systems such as heat recovery and solar plants. Increasing demands on heat recovery and hence antifreeze fluids as an environmental measure also environmentally friendly antifreeze are then requested. Energy from renewable resources such as solar plants is another example where environmentally sound products such as ECO MPG will be used more and more.

Advantages with ECO MPG

Renewable raw materials

Lower carbon foot print in the production process – 70 % less compared to petroleum based MPG.

Non-toxic

May be used in all food refrigeration applications, as ECO MPG is non-toxic. In fact the FDA grade of MPG is used as food additive, in toothpaste, hand cream etc.

Well-known product

Very common on the market for cooling installations and therefore well-known how to handle. For cooling, heat recovery, solar heat plants etc.

Compatible with virtually all construction materials

ECO MPG may be used within any installation since it is not prone to corrode metals.

Readily biodegradable

ECO MPG is Not harmful to the environment as it is readily biodegradable in soil. The product does not contain any boron, phosphate, molybdate, silicate or nitrite.
