Eden Empowers EL Cold Chain with ±1℃ Temperature Stability + Low-Carbon Operation

If cold chain logistics is the lifeline for ensuring the quality of food ingredients, then temperature fluctuations are the most sensitive "pulse" on this lifeline, which needs to be kept stable at all times. From melt-in-your-mouth ice cream to top-quality beef with distinct textures, every failure in temperature control could suddenly halt the freshness of precious ingredients. Facing the dual challenges of strict temperature control and energy efficiency in large-scale cold storage. EL, a Malaysian cold chain company, as an industry pioneer, has been actively exploring new ways to break through. Adopting Eden Refrigeration's CO₂ transcritical solution - the low-carbon refrigeration solution, the company has successfully balanced precision temperature control with environmental sustainability.

Leveraging advanced technology and intelligent management systems, this collaboration sets a new benchmark for the cold chain logistics industry, proving that efficient operation and ecological responsibility can go hand in hand.

EL Cold Chain Project

•  Application: Storage of meat products and ice cream 

•  Facility Types: cold storage, frozen storage and anteroom

•  Total Cooling Capacity: 317.9kW 

    Low-temperature condition: -20°C (237kW)

   Medium-temperature condition: +2℃ (54.5kW) and +5℃ (26.4kW)

CO₂ Transcritical Refrigeration Solution

With the continuous expansion of cold chain logistics, electricity consumption and carbon dioxide emissions are on the rise. low-carbon logistics has become a key focus across the entire industry. To address this, EL Cold Chain has joined forces with Eden Refrigeration to deeply develop sustainable cooling solutions - CO₂ transcritical refrigeration system designed to deliver high energy efficiency and significantly reduce the carbon footprint of cold chain operations.
 

24/7 Operation with ±1℃ Temperature Control

In cold chain logistics, temperature stability is the critical factor in preserving food quality. Taking meat preservation as an example, when temperature fluctuations exceed 1°C, it causes intensified muscle fiber contraction and accelerates protein denaturation. This not only compromises texture but also leads to nutrient loss.In strict compliance with international food preservation standards, EL Cold Chain requires cold storage facilities to maintain precise temperature control within a strict ±1°C range.

Eden's  CO₂ transcritical customized solution for superior performance

• Precision Temperature Control: Using electronic expansion valves to achieve precise refrigerant flow regulation and demand-based cooling. Even in low-temperature conditions of -20°C, it delivers stable refrigeration output while maintaining temperature fluctuations within ±1°C.

• Temperature Uniformity Assurance: Featuring 24/7 fan motor operation and multi-dimensional airflow optimization, the system ensures consistent temperature distribution throughout the storage space, eliminating localized hot spots that could compromise product quality.

• Enhanced Heat Exchange System: The structural reinforcement of key unit cooler components maintain high heat exchange efficiency while providing reliable long-term operational stability, significantly extending equipment service life.   

CO₂ transcritical refrigeration system utilizes advanced variable frequency drive technology combined with high-precision electronic expansion valves to form an intelligent regulation system, delivering exceptional temperature control performance. With 1Hz-level speed modulation capability, the system dynamically matches real-time cold storage load variations. This innovative approach completely eliminates the drawbacks of conventional fixed-speed compressors—which traditionally required frequent cycling on/off just to maintain ±1°C temperature accuracy.

Features of the CO₂ Refrigeration System

• Energy efficiency: The CO₂ transcritical refrigeration system operates with evaporation temperatures of -28°C for low-temperature applications and -5°C for medium-temperature applications. The combined effect of parallel compression and variable frequency control technologies significantly boosts system energy efficiency. Additionally, the system reliably maintains shutdown pressures and a fully automated PLC-integrated control system to ensure operational reliability. 

• Compact design: Compared to conventional refrigeration systems,  CO₂ Rack System enables more compact design while delivering equivalent cooling capacity.

• Heat Recovery Capability: recovering high-temperature hot water (up to 90°C) for dramatically improved comprehensive energy utilization efficiency.
