FAQ / Fragen und Antworten

ENVIRONMENTAL IMPACT


As a natural gas, CO2 is abundant in our atmosphere and therefore has zero impact on the environment. CO2 as a natural refrigerant forms part of the Montreal protocol and is the “green” solution proposed in the legislation. CFC and HFC (Freon) gases are to be phased out and legislation will drive the phase‐out worldwide.




NON CONTAMINANT


Food grade CO2 poses no risk to the product in the event of a refrigerant leak. Ammonia is prohibited by law from being directly used as a refrigerant in the food processing industry.




CENTRALIZED REFRIGERATION PLANT


The refrigeration plant is located in one position to service all the refrigeration requirements centrally, thereby enhancing efficiencies. The refrigerant is piped from a central point to refrigeration coils in each room. In contrast, Freon systems are distributed systems with smaller units installed per room or section, which will impact efficiency and increase costs. A centralized refrigeration system also lends itself to easier maintenance and fault finding.




BLOWER COIL CONTINGENCY


With more than one refrigeration pack serving the cold rooms and freezer rooms of Sernick, the blower coils in each room where more than one blower coil is present are connected so that these are driven from different refrigeration packs. This ensures that, if one refrigeration pack experiences a problem, the rooms can still be refrigerated from the alternative pack while repairs or
maintenance is conducted.




ENERGY SAVINGS


A 30% electrical energy saving over a conventional Freon system can be expected from a CO2 refrigeration system of the same capacity. This is because of the CO2 refrigerant operating characteristics.
