It specialises in offset and roto-offset printing of magazines, catalogues and advertising leaflets for leading publishing companies and large distributions, as well as for leading advertising agencies, banks, insurance agencies, tour operators, present in the Italian and European market.
In order to reduce consumption of electricity and natural gas required to cool the utilities of the rotary press and air conditioning of the production departments of the factory, a recovery system was installed on output from the thermal treatment system of gaseous emissions of 3 industrial rotary machines that work on a continuous cycle, 8000 hours/year.
The heat recovery system supplies an absorbing chiller that produces cooling energy required for the rotary utilities, which need continuous cold water.
The chiller also supplies an air handler used for the air conditioning system in the rooms.
Interventions carried out involve average energy savings of 163 TOE per annum, which is equivalent to the electricity consumption of 180 households. The number of annual EECs obtained is on average 550 EEC/annum for an overall total of 2,760 EEC in 5 years of useful life of the intervention.
