Case Study: Setting New Standards in Renewable Heating – Fenagy Commissions 3 MW CO2 A/W Heat Pump with Shrieve’s Purposely Formulated Zerol RFL-68EP Lubricant

In collaboration with Mozaïek Engineering, Fenagy has achieved a breakthrough in sustainable heating technology with the commissioning of a 3MW CO2 air-sourced heat pump and chiller at a logistics site in Belgium. Enabled by Shrieve's advanced lubricant technology, this pioneering installation replaces traditional gas systems, helping the client move closer to carbon neutrality while setting new industry standards in sustainable heating solutions.

The Challenge

To replace outdated, fossil-fuel-based heating systems with a future-proof and sustainable alternative, Fenagy needed a solution capable of delivering high-performance heating and cooling with minimal environmental impact. Achieving a 3MW heating capacity was essential, but so was ensuring the system's long-term durability, reliability, and compliance with future refrigerant regulations.

The Solution: Fenagy's R744 CO2 Heat Pump

Fenagy's 3MW CO2 heat pump leverages the unique thermodynamic properties of R744, a natural refrigerant with minimal global warming potential. Advanced technology and algorithms manage heating, cooling, and smart ventilation to optimize efficiency and environmental responsibility. The system integrates seamlessly with on-site renewable energy sources, achieving a significant milestone in gas-free heating solutions tailored for logistics operations.

Key Benefits of the Solution

• Future-Proof Compliance: The CO2 (R744) refrigerant ensures the system remains compliant with evolving refrigerant regulations, providing peace of mind for long-term operation.
• Reduced Carbon Footprint: By eliminating fossil fuels, the system helps Fenagy's client move closer to carbon neutrality, offering renewable, gas-free heating.
• Advanced Design and Efficiency: An intelligent heating, cooling, and ventilation system, managed by automated technology, enables optimal performance for the logistics facility.

The Role of Shrieve's Zerol RFL-68EP Lubricant

Shrieve's Zerol RFL-68EP played a pivotal role in supporting Fenagy's engineering objectives. As a specially formulated Polyalkylene Glycol (PAG) lubricant for R744 compressor systems, Zerol RFL-68EP provides:

• Enhanced Component Protection: Designed to protect compressor parts in challenging conditions, Zerol RFL-68EP supports durability even under the demanding requirements of a high-capacity system.
• Extended Oil Drain Intervals: With proven long-term reliability, the lubricant reduces maintenance needs, offering cost savings and operational stability.
• Compatibility with R744 Refrigerant: Tailored specifically for CO2 applications, Zerol RFL-68EP ensures efficient lubrication and optimal performance, reinforcing the system's environmental goals.

Shrieve's long-term relationship with Fenagy has allowed the engineering team to focus on installation complexity and scale, while Zerol RFL-68EP ensures consistent reliability across operations. This collaboration has progressively enabled Fenagy to take on greater and more complex challenges.

Impact on the Industry

This installation not only highlights Fenagy's leadership in heat pump innovation but also Shrieve's commitment to supporting carbon-neutral solutions. The project underscores the role of heat pumps in replacing conventional heaters within logistics operations, making reliable, renewable energy sources an option for essential facilities.
