Systems Architecture – CO2 Booster Technology
Features of
• HFC-Free System, CO2-Only
• CO2 is a Natural Refrigerant, GWP=1
• High quality Heat Reclaim opportunities
• Simple Oil Management System
• Efficient Bitzer compressors proven in thousands of
installations
• Electronic Expansion Valves in all evaporators
• Familiar components to HFC DX system

Systems Architecture – CO2 Booster Technology
• Operates as a
vapor compression
cycle or direct
expansion system
• Two stage
• Low stage for
low temperature
• Upper stage for
medium temp
and heat of
rejection
Examples of North America Industrial Projects using
Trans-critical CO2 Systems
Cold Storage Facilities
• Caputo’s - Carol Stream, IL *
• House of Spice – Elk Grove Village, IL *
• Best Foods – Forest View, IL
• Apple Warehouse – New Castle, ON
• Woodman’s Warehouse Freezer – Beloit, WI
Ice Rinks
• City of Anchorage – McDonald Center *
• City of Anchorage – Sullivan Arena *
• City of Anchorage – Ben Boeke Arena *
These are only a sampling of the Industrial projects utilizing CO2 Booster Systems in North
America
Benefits of
• HFC-Free System, CO2-Only
• CO2 is a Natural Refrigerant, GWP=1
• High quality Heat Reclaim opportunities
• Simple Oil Management System
• Efficient Bitzer compressors proven in thousands of installations
• Electronic Expansion Valves in all cases
• Familiar components to HFC DX system
• Low-temp system very similar to our current SNLTX2 cascade system

Understanding Challenges & Benefits with CO2 Booster Systems
CHALLENGES
BENEFITS
• Affords the opportunity to utilize the most environmentally
friendly and energy efficient refrigerant
• Elimination of Process Safety Management and Risk
Management Program regulations which reduces the need
for dedicated employee oversight.
• Provides the ability to locate your facility in places you may
not be able to otherwise due to liability issues
Complete Self Contained Refrigeration System
NXTCOLD systems are factory manufactured and shipped to
job site ready for installation
BENEFITS
• Offers simple “plug and play” installation
• Installation and start-up can be achieved in one day
• Allows single point access for maintenance and service
• System flexibility offers cooler, freezer and blast freezer
solutions with capacities ranging from 5 TR to 150 TR.
Offers a Modular, Distributed Refrigeration Solution
BENEFITS
• Offers flexibility in temperature and redundancy
• No longer will a dedicated machine room be needed allowing
that space to be utilized for revenue producing activity
• Eliminates loss of large refrigerant charges and associated
liability
• Ideal for automated demand response programs.
• Standard units can be mounted on rooftop or ground level.
ERIC Patented Control Technology
How NXTCOLD does it and why it’s better:
• ERIC (Electronic Refrigerant Injection Control)
proprietary technology makes the low charge
possible.
Lowest Capacity Weight: 7,500 lbs. 10,000 lbs. 12,500 lbs. 15,000 lbs.
Highest Capacity Weight: 15,000 lbs. 20,000 lbs. 25,000 lbs. 30,000 lbs.
