The Refrigerant Fluid Used on "Plug-In" Systems for Commercial Refrigeration

Kryon ® 290 (propane for refrigeration use) is a HC hydrocarbon belonging to the linear saturated alkane series; Hydrocarbons are refrigerants composed exclusively of carbon and hydrogen atoms. These compounds are already naturally present in the atmosphere and therefore do not represent a risk from an environmental point of view (greenhouse effect and ozone damage).

Kryon ® 290 , like all hydrocarbons, is a highly flammable gas (class A3), and the relative implications in terms of safety must therefore be duly considered during storage, transport and handling; the propane charge in "plug-in" type refrigeration systems (e.g. refrigerated counters and refrigerated display cases) is in fact limited to a maximum of 150 grams.

Gas requires the use of mineral-type oils in the compressors of the refrigeration units, which avoids the humidity problems associated with the use of synthetic lubricants.

Applications:

Kryon ® 290 is mainly used in commercial refrigeration, on positive temperature systems : counters and cold rooms, ice production machines , vending machines. It is also used in some industrial plants at negative temperatures.

Performance:

• The absence of substances potentially harmful to the ozone layer and the extremely reduced greenhouse effect has allowed the progressive affirmation of Kryon ® 290 as a working fluid in refrigeration systems with reduced charges
• Refrigeration systems with high gas loads can only be created by providing for a confined refrigeration plant and the use of a heat transfer fluid

Recommended Lubricants:

Kryon ® 290 requires the use of mineral oils, which avoids the problems of humidity associated with the use of synthetic lubricants.
