Barriers identified for this technology
- Liability
- Flammability of R-290
- Uncertainty on skill level of service technicians
- Cost:
- Technical solutions to mitigate flammability risks has extra
costs;
- Main components imported;

Key Findings of the Projects until now
- The R-290 modular chiller will help both companies to develop new solutions
and NEW business models.
- Improvement of energy efficiency
- Systems require less maintenance
- Reduced installation time
- Safe place to assembly and maintain chillers in the factory.

Key Findings of the Projects until now
- Refrigerant charge reduction
- Do not require trained technicians in the field
- Raise awareness regarding the advantages of using propane in refrigerating
systems.
- The adoption of the R-290 will limit the future use of synthetic refrigerant with
high GWP
- The project with Eletrofrio and Plotter Racks companies will result in 157.6 t of
ODS elimination.
