Case 1: Use of ground water for cooling

Medium-large company specialized in production and processing of plastic materials

TARGET

Structuring a cooling system that allows to save on the consumption of electric energy needed to produce the cooling energy useful for the production and processing of plastic.

OPERATION

Installation of a cooling system with groundwater with water supply directly into the circuits by directly cooling the lines of dies and dies.

BENEFITS

Our plant has allowed the company to save over € 220,000 / year and to obtain 884 TEE / year, around € 84,000 / year.

Case 2: Replacing traditional compressors with variable speed machines

Intervention carried out at a company specialized in the production of packaging materials such as extruded net, woven and film.

TARGET

Reduce the incidence of electricity costs (over 10%) in the generation of compressed air used by printers and packaging machines.

OPERATION

After a consumption analysis, it was decided to insert a variable speed compressor to modulate the production according to the load and use the remaining compressors only at full load.

BENEFITS

The investment required was € 90,000 and saved 265,000 kWh / year and obtain the TEEs.

Case 3: Cooling system efficiency with freecooling

Company specialized in the production of colored masterbatches and additives for different application sectors

TARGET

Reduce the consumption of electricity by using a freecooling system that uses the presence of outside air at a lower temperature of the chilled water.

OPERATION

Replacement of air-cooled chillers with a freecooling system and a new high-efficiency air-cooled chiller.

BENEFITS

The intervention has allowed to obtain a guaranteed saving of electricity equal to 350,000 kWh, corresponding to about € 60,000 / year. The initial investment was € 170,000.
