Compact CO2 refrigeration
3rd April 2026
ITALY: Prisma is a new range of transcritical CO₂ refrigeration units from Italian manufacturer Arneg offering high performance in a compact footprint.
Said to be ideal for mini-markets and small retail stores, Prisma is an outdoor-installable unit available in both normal and low-temperature versions.
A key strength is said to lie in the integration of the gas cooler within the unit’s structure. This design choice reduces the overall footprint and simplifies installation, eliminating the need for external components.
Units are available as 1-, 2- and 4-fan options in a unified, compact design with a length of up to 2550mm.
Using reciprocating compressors and EC axial or radial fans, the units claim stable operation up to 45°C ambients.
