In this specific case study, the customer asked for a footprint reduction of the refrigeration equipment for a light industrial application with a standard transcritical CO₂ system, keeping the same cooling demand. EPTA already supplied refrigeration packs for a previous cold‑storage configuration, operated with three ECO₂Large pack. The updated solution delivers multiple improvements, including reduced machine‑room space requirements, lower refrigerant volume, decreased logistics and technical‑service needs, and fewer spare‑parts requirements.
From three ECO2Large packs down to one ECO2Giant
Customer needs:
- MT design load 522 kW
- LT design load 98 kW
Client request:
- Same design load
- Lower footprint
The benefits for the customer are mainly related to the system simplification that the new proposal offered. In details:
- lower refrigeration pack footprint: the space occupied by the machines is significantly reduced, either improving serviceability or machinery room size;
- lower installation costs: thanks to the lower number of connections to be done on site;
- lower refrigerant charge: faster commissioning ;
- lower logistics costs: two packs of the same size can fit a single 40' High Cube container, as shown in the rendering above;
- fewer technical services and spare parts needed: thanks to the lower amount of components involved.
Finally, the proposed solution is also compatible with hot gas defrost option for future upgrades.
Improvements:
- Save square meters required for machine room
- Reduction in required refrigerant volume
- Reduction of logistics costs
- Reduction in required technical service
- Reduction in spare parts requirements
This system has also the possibility of a future Hot Gas defrost option equipment.
