Cold Jet RE-CO2 3500 CO2 Recovery System

The RE-CO2 3500

Unmatched CO2 Recovery: High Capacity, High Efficiency.

Cold Jet’s new high-volume CO2 recovery unit offers a sustainable and efficient solution for dry ice production facilities looking to minimize their environmental impact. These cutting-edge systems capture exhaust CO2 gas and convert it back into reusable liquid CO2 through a seamless compression and cooling process. This innovative approach reduces emissions and reliance on external suppliers while significantly boosting efficiency—effectively cutting liquid CO2 costs in half.

Designed with operators in mind, the modular and containerized unit ensures quick and hassle-free installation with minimal infrastructure changes. Beyond its core function, this system can stabilize pressure in liquid CO2 feed tanks, significantly enhancing the overall performance of a dry ice plant. The standard unit boasts a capacity of up to 7,716 lbs/hr (3,500 kg/hr) and utilizes a CO2-based closed-loop refrigerant system, all within a compact 492 x 334 in (12.5 x 8.5 m) footprint.

Cold Jet also offers a range of optional add-ons to further tailor the system to specific needs. These include Storage Tank Pressure Control for consistent dry ice machine performance, a CO2 Gas Dryer System to maintain liquid CO2 quality, and an Energy Efficiency Package that can reduce energy consumption by up to 10%. For businesses focused on sustainability reporting, a CO2 Emissions Reporting Package provides precise data on captured and saved emissions, while Heat Recovery options further optimize energy use and reduce operational costs.

The Cold Jet Difference:

The RE-CO2 3500 Advantage

Ultra-Low Energy Use

Our solutions boast the lowest energy consumption compared to similar systems, translating into significant efficiency and cost savings for you.
R744 Refrigerant

We use natural CO2 (R744) as the refrigerant. This means our units avoid harmful environmental refrigerants, keeping things green.
Flexible Operation

Each unit offers a broad operational range, effortlessly adjusting from 25% to 100% of its maximum capacity. They adapt perfectly to varying CO2 gas input.
Fully Autonomous

Our units are designed to run themselves, requiring no operator intervention once they're up and running.
Containerized Setup

Forget about new buildings or renovations. Our units come ready-to-go in standard shipping containers, making installation straightforward.

RE-CO2 3500 Features

Remarkably Energy Efficient: Our system uses a mere 135 kWh or less per ton of CO2 recovered. Compressors intelligently adjust to demand, ramping up slowly to prevent power spikes.
No Synthetic Refrigerants Required: Enjoy peace of mind knowing our system operates without the need for harmful synthetic refrigerants.
Full Autonomy: This system truly works in the background, allowing for seamless, hands-off operation.
Unmatched Production Flexibility: Whether you’re running one or six pelletizers, our system automatically adapts to precisely match your production needs.
Easy Installation, Compact, and Protected: Thanks to its containerized design, installation is a breeze, it takes up minimal space, and it’s fully protected from the elements.
Lower Maintenance Costs: Unlike complex ammonia systems with their large compressors and intricate technical overhauls, our oil free compressors require significantly less maintenance.

Storage Tank Pressure Control

By connecting a gas line between the client storage tank and our unit's storage tank, the recovery system ensures pressure in the client tank is effectively controlled and stabilized. This bi-directional pressure management ensures consistent performance for your dry ice machines, enhancing operational efficiency and maintaining optimal conditions for the storage and use of CO2.
CO2 Gas Dryer System

A gas dryer can be added, to control the moisture content or the pressure dew point of the CO2 gas before liquefaction. This is to ensure that the liquefaction skid can work correctly and that the liquid CO2 meets quality standards.
CO2 Emissions Reporting Package (ESG)

Cold Jet offers a CO2 emissions reporting package that accurately measures the CO2 emissions saved through our system. By tracking the input and output flows, we provide precise and reliable data on the CO2 emissions captured and saved, enabling transparent reporting and support of sustainability goals.
Heat Recovery

Excess energy generated at the plant site offers an opportunity to enhance the efficiency of the entire process. By utilizing this surplus energy, the system's initially low energy demand can be further optimized. This integration not only improves the overall efficiency of the system but also contributes to the smoother operation of the plant itself. The result is a reduction in operational costs, which can lead to more sustainable operations and better financial outcomes for your facility.
