Glycol-based ‘Hydroloop’ Refrigeration System by FREOR is an alternative to remote refrigeration system, linking several plug-in refrigerators and / or cold rooms to the glycol condensing system. A glycol solution is circulated within a closed loop as a medium to carry out heat from display units to the outside of the store, using a water pump and an externally located dry cooler. Only one loop for both medium and low-temperature display cases is needed, allowing faster store set-up with reduced system installation and maintenance costs.
The system proved to be energy-efficient, cost-effective, friendly to the environment, and conforms to the latest commercial refrigeration environmental regulations. Combined with plug-in refrigeration equipment operating on low GWP refrigerant propane (R290), it maintains a strong position as a future-oriented refrigeration solution.
