SEA-ECO COOLING UNITS R744

Product catalog summary

Introduction
The SEA-ECO series by CLIMAREM offers a future-proof and efficient refrigeration system using the natural refrigerant R744 (CO2), which is environmentally friendly with a Global Warming Potential (GWP) of 1. This system is designed for marine conditions, ensuring compliance with Marine Classification Bodies and reducing both capital and operational expenditures.

Specifications
The SEA-ECO units are compact and available in split versions, featuring a two-stage booster system with two compressors for different evaporation temperatures. The system includes a shell and tube heat exchanger made of titanium and P355NH steel, designed to handle high pressures of R744. The refrigeration automation is provided by Danfoss and Castel, ensuring precise control.

Components
The system comprises semi-hermetic reciprocating compressors, CSX coolers for high-pressure operation, a flash tank certified for 80 bar, and a pressure maintaining valve by Danfoss. These components ensure efficient operation and compliance with maritime standards.

Advantages of CO2 Refrigeration
CO2 systems offer excellent environmental compatibility, high efficiency, potential for heat recovery, and good thermal properties. They are cost-effective due to lower purchase and maintenance costs and are not subject to legal restrictions like synthetic refrigerants.

Performance Data
The SEA-ECO series includes models with varying cooling capacities for freezing and cooling chambers, ranging from 1.5kW to 21.5kW. The systems operate at voltages of 380-420V or 440-480V and frequencies of 50Hz or 60Hz, with the ability to adjust for increased capacity and power.

Conclusion
The SEA-ECO refrigeration units by CLIMAREM provide a sustainable and efficient solution for marine refrigeration needs, leveraging the benefits of CO2 as a refrigerant. For more information, contact CLIMAREM at their Gdynia office.

| COOLING SYSTEMS USING ECOLOGICAL REFRIGERANT The safety and quality of food products in cold stores on ships is a priority task for each vessel. This can only be guaranteed with a suitable refrigeration system. On the other hand, for operators, the eﬃciency of the refrigeration system and compliance with current standards of Maritime Class Societies are vital, as allows to reduce investment (CapEx) and operating costs (OpEx). Therefore, refrigeration systems using natural refrigerants are a suitable alternative to the gradually phased-out HFC refrigerants. Because R744 refrigeration systems...

SEA-ECO COOLING SEA-ECO COMPONENTS Our cooling units consists of the following components: Are the heart of the entire system. The booster type system, thanks to the use of two semi-hermetic reciprocating compressors with diﬀerent operating ranges, allows to obtain the evaporation temperatures required in cold stores and freezers. The new Ecoline series of Bitzer compressors, adapted to the new refrigerants, ensures lower electricity consumption while maintaining high system eﬃciency. In Ecoline compressor’s range, the COP (energy eﬃciency coeﬃcient) has been signiﬁcantly increased by introducing...

WHY IS CO2 REFRIGERATION A SMART SOLUTION? CO2 (R744) refrigeration system can be found more and more often, especially in food refrigeration. No wonder, because it is distinguished by numerous advantages: GOOD ENVIRONMENTAL COMPATIBILITY: CO₂ has no ozone depletion potential and has a low GWP (1), meaning that CO₂ refrigeration systems are very environmentally friendly. EFFICIENCY: CO₂ is a substance with high availability and much lower purchase costs compared to synthetic refrigerants. Thanks to this, as a user of the CO₂ cooling system, you benefit from lower operating costs. Low maintenance...
