2 compact Refrigeration Rack Transcritical CO 2 booster Electrical cabinet delivered wired and mounted. Energy saving: Frequency converter on MT and LT compressor (option). Emergency condensing unit integrated. Suction accumulator on negative rack (option). Energy saving: Heat recovery module with several options available. A CONCEPTION BASED ON ENVIRONMENTAL EFFICIENCY: The new range of refrigeration Rack MiniCO 2 compact uses the natural fluid carbon dioxide (CO 2 ) to provide durable and energy efficient refrigeration solutions. Specifically designed for the supermarkets and discounters, the MiniCO 2 compact system covers a wide range of cooling capacities. In temperate climates, the MiniCO 2 compact demonstrates up to 10% of energy savings compared with the traditional HFC refrigeration systems, leading attractive life cycle costs and a short period of return on investment. The CO 2 is the neutral refrigerant by excellence; it has a minimal global warming potential (GWP) for the planet, and a zero Ozone Depletion Potential (ODP). He is completely compatible with the F-Gas regulation. TECHNICAL CONCEPT: - Positive and negative racks stacked together on one main frame. - From 2 to 6 positive compressors: - 20 to 300 kw. - From 1 to 4 negative compressors: - 2 to 130 kw. - Pressure design: 25,45, 120 bar. - Active oil separation system. - Multiple vertical liquid receivers. - Integrated electrical cabinet including the control and protection of the Gascooler. - Control via dedicated automation, in open protocol. - Frequency inverter on positive compressor (standard) and negative (option). - Emergency condensing unit, factory mounted. - Heat recovery module integrated (option). PRODUCT BENEFITS: - Safe running. - Energy optimization. - Customization / adaptability. - Machine with PED compliance, risk category III. - Small footprint. Adaptability: Electrical cabinet with customized user connections. Semi-automatic backup running mode. Access to components from the front face. Oil separator and oil receiver. Double filter drier line (option). Specific control dedicated to transcritical CO 2 applications, with algorithm for efficiency ratio optimization. Multiple receivers PED Cat III or IV, from 66 liters to 2 x 198 liters. INSTALLATION SUTIONS: - 100% natural fluid CO 2, compatible F-GAS. - Heating and sanitary hot water production. - Energy saving. - Adapted for machine rooms with small dimensions. - Easy maintenance. 800 mm mm Small footprint: Positive 300 kw and negative 150 kw in 900/4000 mm on the floor mm with heat recovery.

3 compact Options for better environmental efficiency. THE ECO-COMPRESSOR. Economizer cycle: Addition of a complementary compressor operating as economizer. Reduction in the compressors size. Better efficiency of the gas compression in medium pressure: ~30%. COP improvement: ~15%. HEAT RECOVERY MOUNTED AT THE RACK DISCHARGE: The CO 2 has excellent properties, particularly a high temperature of discharged gas, allowing to recover more energy at higher temperatures, and this on a regular basis. These characteristics allow to combine simultaneously the production of heating water and hot sanitary water through several heat exchangers. Various configurations are possible with or without gas cooler bypass and always equipped with a set of anti-boiling bypass valves. Directly mounted on the rack, the heat recovery module is connected to the refrigerant circuit, and electrically wired. Possibility to add pumps and energy meter (options). Controlled valves Sanitary Hot Water exchanger Water heating exchangers FREQUENCY INVERTER: The frequency inverter is delivered wired on the MT rack and optionally on the LT rack to allow an energy optimization by precise adjustment of the refrigeration capacity to the needs of display cabinets and other cooling devices of the store. These guarantee a flexible running of the rack during under load period (winter) by reducing the Startup/shutdown cycles of the compressors. They also allow to bear the peaks demand (summer) while using a compressor of smaller size (functioning in over-frequency). Frequency inverter LT rack (option) Frequency inverter MT rack
