A common issue across the HVAC and process cooling sector is the belief that selecting larger capacity R290 natural refrigerant chillers is difficult. This concern often links to uncertainty around future F-Gas legislation and wider decarbonisation targets.
This view has developed due to the historical focus of many chiller manufacturers. Large capacity systems have, for years, centred on synthetic F-Gas refrigerants. As the industry begins to shift, the availability of large capacity, single unit R290 chillers can appear limited to specifiers.
For projects that require a future-proof, low carbon design, the challenge is rarely the strategy itself. The issue is access to commercially scalable R290 solutions that meet higher capacity demands.
However, large capacity natural refrigerant chillers are already available and can support high-performance cooling across both HVAC and process applications.
A Proven R290 Solution Through Pure Thermal
Pure Thermal works in partnership with ENERBLUE S.R.L. to supply a range of R290 chillers with nominal capacities up to 900kW. These systems are designed to meet the needs of complex and high-demand projects.
These chiller ranges have not been adapted from F-Gas systems in response to legislation. Instead, they come from over 15 years of dedicated R290 chiller development. Enerblue has built a strong reputation in this area, well before regulatory changes began to influence refrigerant selection.
Key Capabilities of Large Capacity R290 Chillers
Pure Thermal’s R290 chiller range provides:
- Large capacity single unit chillers up to 900kW
- Full or partial heat recovery to support efficient energy use
- Simultaneous heating and cooling for flexible system design
- Compatibility with HVAC and production cooling applications
- Systems suitable for low temperature process cooling
- Designs aligned with future F-Gas phase-out requirements
- Retrofit-focused options to support integration with existing systems
These features allow specifiers and end users to meet performance, compliance, and carbon reduction targets without compromise.
Addressing the Real Barrier
The limitation is not the capability of R290 technology. The key challenge is access to solutions that operate at the scale required for larger projects.
As demand for low carbon cooling grows, more projects now require systems that can deliver both efficiency and compliance. This includes the ability to recover heat, reduce emissions, and support long-term operational goals.
Industry Considerations
Across current projects, several common challenges are emerging:
- Limited availability of single unit large capacity R290 chillers
- Increasing pressure to meet refrigerant compliance standards
- Demand for higher system efficiency
- Greater interest in simultaneous heat recovery
- Stronger focus on reducing the carbon impact of cooling systems
Pure Thermal supports clients in addressing these requirements with proven R290 solutions that meet both technical and environmental targets.
