Many businesses in recent years have been looking to “future-proof” their operations and the food-retail industry is no exception. Supermarkets, convenience stores, and other food retail establishments have been turning to products and services that offer an environmentally friendly alternative for their business. Refrigeration systems and display cases are no exception.
Companies are seeking equipment that withstands the impact of climate change, is energy efficient and can accommodate technological and regulatory changes for the foreseeable future. When it comes to refrigeration systems, advances in technology have given manufactures the ability to build and create systems that stand up to those changes. A natural refrigerant, CO2 is a great option for many operations and makes it a viable option across a wide range of applications.
Since the middle of the last decade, CO2 has gained traction as a refrigerant in both secondary and direct expansion systems across the grocery and supermarket industry. One system, in particular, CO2 Transcritical Booster System, has gained notoriety because it relies solely on CO2 as a natural refrigerant in the system and removes the needs for traditional refrigerants with various GWPs. And with increased regulations being put in place, food retailers are shifting towards putting these systems in place in an effort to rejuvenate their operation and put their best foot forward.
Other benefits of this particular refrigeration system are their higher heat reclaim opportunities which improve the overall store energy performance that challenges food retail establishments today. In most cases, CO2 booster systems can have a lower installed cost as it is more efficient in a cooler climate which allow for smaller compressors and reduced refrigerant line sizes and with the advancement of newer technology becoming more efficient is all climates. CO2 has the flexibility to vary from a traditional centralized system to distributed CO2 with a wide range of applications from small format to supermarkets to industrial and ice rinks operations.
