CO2 Ecopack is a customizable transcritical rack, designed mainly for commercial application. Built on a low and narrow frame, it is designed for small spaces and easy maintenance. This model can be assembled with maximum 4 MT and 3 LT reciprocating compressors and provide cooling capacity up to 135 kW. Due to its simple, small frame design, this unit is the optimal choice for installing a medium size refrigeration system.
GREEN SOLUTIONS | This unit is a part of Refra‘s environmentally friendly product group, as it is made using CO2 refrigerant. Such low GWP solutions are designed to have better efficiencies and capacities, as well as less environmental damage.
(low and medium capacity, up to 150 kW, low AND medium temperature);
CO2 refrigeration racks for supermarkets are a little bit more complex systems that can work at two or more temperature regimes, usually: around -33 °C for low temperature cabinets and cold rooms and around -10 C for medium temperature cabinets and cold rooms. Additionally, such system could have an air conditioning option and produce 7 °C glycol/water. If possible, it is recommended to use heat recovery to not waste energy. Heat recovery from CO2 system could produce hot tap water (up to 65 °C) or water for space heating (up to 40 °C).
Such CO2 refrigeration racks are standardized but can be adapted to customer needs (specific capacity, options).
(high capacity, from 150 kW; low AND medium temperature).
CO2 refrigeration racks for hypermarkets are always designed specifically for the customer. Temperature settings are the same as for supermarkets, but because of the higher capacity, can differ to better suit the project. For higher capacity systems it is recommended to use parallel compression as energy savings become noticeable.
CO2 refrigeration system for hypermarkets is a customized system that includes low temperature refrigeration, medium temperature refrigeration, heating and can include AC cooling. This kind of refrigeration rack is designed according to customer needs and can be integrated into building management system, which makes refrigeration system easy to monitor and control. High capacity systems can be split to separate refrigeration racks. This helps to achieve very high capacity and provides additional reliability. The key points of this solution are: The key points of this solution are: customizable, environmentally friendly, energy efficient.
