Description
Compact transcritical CO₂ refrigeration packs with built-in gas cooler for simultaneous production of positive and negative cooling in commercial applications from 30 to 100 kw of refrigeration capacity.
- Example supermarket installation
The ECO2CUBE range has been designed to meet the refrigeration needs at different temperatures of medium sized supermarkets or other commercial establishments.
CONSTRUCTION
- Compact acoustically insulated construction, in a sheet steel casing with weatherproof epoxy paint, with integrated electrical panel and gas cooler.
- Emergency unit for R-744 maintenance.
FANS
- EC electronic fans with speed regulation by proportional control of the condensing pressure.
REFRIGERATION CIRCUIT
- Set of R-744 semi-hermetic compressors with parallel compression:
– Up to 4 transcritical compressors for positive temperature, one of them INVERTER.
– Up to 3 negative temperature booster compressors, one of them INVERTER. - High-pressure section (PS: 120 bar) made of high-pressure copper alloy tube and equipped with:
– Oil separator-accumulator with filter and electronic injection per compressor.
– Double safety valve.
– Double pressure control valve. - Medium-pressure section (PS: 52 bar) made of copper pipe and equipped with:
– R-717 receiver with double safety valve (PS: 52 bar).
– Pressure regulating valve with relief to medium pressure.
