Frigofluid supplied a Venetian plastic molding company a chiller with built-in free-cooling mode, as part of the expansion of the production system (addition of new presses). A consultancy that concerned not only the technical solution, but its insertion into the entire heating and air conditioning system of the plant.
- Savings on energy consumption.
- Support for the expansion of the production plant.
- Reliable performance.
Company: Plastic material molding company.
Application field: end user, process industry.
Localization: Veneto – Treviso province (Italy).
Frigofluid’s customer company is active in the molding of plastic materials.
Process optimization and energy consumption were point of common interest among Frigofluid and the Customer.
Project needs and objectives
Process: Refrigeration of plastic presses; expansion of the production site to serve n. 5 presses, to be installed in the future.
- Temperature of output water: + 15 ° C (ambient air temperature: + 35 ° C).
- Cooling capacity: 55.8 kWf, deduced from the data of the capacity of each press (ton measurement).
Consumptions required: consumption savings, showing data and different technical solutions.
Further requirements: condensation heat of the systems to heat or mitigate the production areas during the cold months and thus save on the methane bill. Indeed, the continuous saving of the system, allowed by free cooling, was more convenient: in fact, the heating of the shed by means of the refrigerating solution involves air distribution ducts and shutters for thermoregulation.
Solution by Frigofluid
Supply: Free-cooling chiller RWC-EFC 60/2 ax (dimensions: 2450 x 1330 x 2455 mm).
- Possibility of maintenance intervention without total shutdown, thanks to the splitting of the refrigeration circuits.
- Maximum energy saving through independent fans (electronically-controlled brushless axial type).
- Compatibility with Industry 4.0 (certified).
Success factor: the control units of the Free-Cooling series allow continuous savings of the system without any design or additional works. Data were obtained by comparing customer consumption information with the “Free-cooling energy saving card” program, which simulated two water working temperatures: + 15 ° C and + 20 ° C.
Achieved results: achievement of the performance and consumption indicated.
