Ecofrost® 290 (propane) is an hydrocarbon HC belonging to the linear saturated alkanes. Hydrocarbons are refrigerants which are exclusively composed of carbon and hydrogen atoms; these compounds occur naturally in the earth’s atmosphere, therefore it does not represent an environmental risk (greenhouse gas emission and ozonedepleting).
Ecofrost® 290 as all other hydrocarbons, is a highly flammable gas (ASHRAE safety rating A3). For this reason the safety implications must be appropriately considered during operations of storage, handling and transport. In refrigeration “plug-in” systems (e.g. refrigerated showcases and cabinets) propane charge does not exceed 150 grams.
Ecofrost® 290 requires the use of mineral oil in cooling systems’ compressors, thus avoiding humidity problems relating to use of synthetic lubricants.
Ecofrost® 290 is mainly used in commercial refrigeration systems, (positive temperature): supermarket refrigerated display case, ice maker machines, vending machines.
Ecofrost® 290 is also used in some low temperature industrial system.
- The absence of ozone layer depleting substances and its extremely low greenhouse gas emission allowed Ecofrost® 600a to be used increasingly as refrigerant in low charge systems.
- Refrigerating systems with high gas charge can be only achieved when a confined cooling system and a transfer fluid are provided.
