R-515B / 25 lbs

R-515B Low-GWP Refrigerant

Non-Flammable Efficiency with Uncompromising Eco-Compliance

Future-proof your cooling operations with R-515B, the premium low-Global Warming Potential (GWP) alternative designed to replace legacy R-134a. Engineered as an azeotropic HFO blend with zero temperature glide, R-515B provides a highly stable solution that delivers an impressive 77% reduction in GWP compared to R-134a—all while maintaining an ASHRAE A1 non-flammable safety rating.

Key Features:

• Non-Flammable (A1 Safety Rating): Classified as non-toxic and non-flammable under ASHRAE Standard 34, removing the complex architectural and leak-detection restrictions of A2L flammable alternatives.
• California CARB & EPA Compliant: With an ultra-low GWP of 292 to 299, R-515B completely satisfies the strict California Air Resources Board (CARB) and federal EPA AIM Act regulations for new commercial chillers, heat pumps, and high-ambient air conditioning systems.
• Zero Temperature Glide: This true azeotropic blend acts identically to a single-component gas, preventing fractionation and allowing for simple servicing and topping-off.
• High-Temperature Performance: Features a higher critical temperature and lower discharge pressures than R-134a, allowing it to perform seamlessly in demanding high-ambient environments and heat pump water heating applications.
• Design Compatibility: Engineered to match the exact capacity and efficiency profiles of R-1234ze, allowing it to be utilized across broad equipment architectures validated by major global OEMs.

Note: R-515B is designed for new equipment installations or system retrofits that have undergone specific OEM-approved modifications. It must always be charged in the liquid phase to maintain correct molecular composition.
