FAQ / Fragen und Antworten
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.
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
maintenance is conducted.
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.
