The success story of HFOs in commercial refrigeration: The Future Roles of HFOs are a near drop-in, environmentally preferable alternative to HFCs that meet / exceed global environmental imperatives. Global Warming Potential: Pure HFOs have GWPs that are 99.9% lower than the products they replace. Efficiency: HFOs provide greater efficiency versus other ultra-low GWP refrigerants.

- Water usage
- Effluents
• Atmospheric Chemistry assessed by Prof Nielsen (U. of Copenhagen) and
others including members of the UNEP Scientific Assessment Panel.
- GWP = 1 or less
- No POCP impact
• Assessed by US EPA (SNAP) and EU (REACH)
- SNAP approved
- No Use Restrictions under EU REACH
• Fits Resource Efficiency Model
- High value promotes recovery, reclamation and re-use
• Energy Efficiency drives Refrigerant Selection
- HFO blends designed to address specific thermodynamic ranges
HFOs Are An Excellent Solution

Conclusion
• HFOs are a near drop-in, environmentally preferable alternative to
HFCs that meet / exceed global environmental imperatives.
- Global Warming Potential: Pure HFOs have GWPs that are 99.9% lower than
the products they replace.
- Efficiency: HFOs provide greater efficiency versus other ultra-low GWP
refrigerants.
- Availability: The versatility and availability of HFOs can help speed up the
implementation of lower GWP systems, particularly in developing countries at the
start of their phase-out.
- Ease of Implementation: For customers looking for simple, cost-effective
solutions that do not require expensive new systems, HFOs offer a near drop-in
solution.
• There is no single solution for every refrigeration application, but every
application can have a smart solution for both the environment and the
user.
- HFOs deliver cooling performance and energy efficiency while driving down
GWP, and are an essential component of the future of refrigerants.
