Since the 70s Danieli has established a division that specializes in environmental protection. Today Danieli Environment offers a full range of proprietary technologies for air pollution control, water treatment, energy saving. solid waste recovery and noise reduction.

The green manufacturing emphasizes the concept of technological integration between machineries with environmental solutions. Less consumption of natural resource and zero emission of wastes are the bases for the full and effective safeguard of the environment. Auxiliary plants such as water treatment plants, fume treatment plants, heat and waste recovery systems become the crucial environmental technologies imprinting the eco-green performances benchmark over the metal production.

To produce green metal means to take in account the green footprint by optimization of natural resource use and avoid emission of pollutants and the GHG on the environment. It means to account the use of water, use of energy, discharge of waste, air pollutants, minimize the noise and electromagnetic dispersion, offer the safety working place for the humans and discharge less GHG per unit of production.

Absorption Chiller Systems

Steelmakers' expanding search for green solutions and simultaneous need to optimize plant costs has led to a rediscovery of chillers, "absorbers", which have been in general use by the market for a long time. These systems make it possible to produce refrigerated water that can be used for technological purposes (to cool motors, laser welding machines, aftercoolers, etc.) and for air-conditioning systems of electrical cabins, laboratories, offices, etc.

Different from the electrical chillers, absorption chillers activate their process using hot water (e.g., available in the cooling return of the furnaces) instead of electrical power.

The above is feasible because the chillers' electrical compressors are replaced by generators and absorbers, which perform the same function as the compressors. Evaporators and condensers work in the same way in both equipment.

The use of lost thermal energy by the Danieli absorption chiller system guarantees energy savings, recovery of the thermal waste, return on investment ROI and green energy credits.
