The solution aims at using of a closed water circuit to cool the cooling lubricant emulsion in drawing lines.

The closed circuit allows for recovery of heat in heat plate exchangers. The recovered heat is used for heating of production and storage halls in MANEX production plants in Skawina. In standard solutions, the heat (ca 180 kW of power for one line) gained in the drawing process is transferred to the environment and the process requires compression-type refrigerating system
