Key Features & Specifications

Chemical Composition & Global Warming Potential (GWP)

R1234ZE, also known as trans-1,3,3,3-tetrafluoropropene, is a HFO-based refrigerant featuring an ultra-low GWP of approximately 7 (compared to GWP 1,430 for R134a). It carries zero Ozone Depletion Potential (ODP), making it fully compliant with the latest environmental regulations such as the Kigali Amendment and EU F-Gas rules.

Z

Ultra-Low Global Warming Potential

R1234ZE’s GWP of ~7 dramatically reduces greenhouse gas emissions compared to traditional HFCs.

Z

Energy Efficiency

Optimized thermodynamic properties allow refrigeration and A/C units to run more efficiently, lowering electricity consumption by up to 10 % in typical cycles.

Z

Zero Ozone Depletion Potential

Fully ODP-free, R1234ZE complies with all current and upcoming international environmental standards (Montreal Protocol, Kigali Amendment).

Z

Seamless Retrofits

In many vehicle A/C systems and commercial chillers originally designed for R134a, R1234ZE can be used with minimal hardware changes.

Z

Reduced Charge Volume

Due to its higher volumetric cooling capacity, R1234ZE often requires up to 20 % less refrigerant mass to achieve the same cooling effect, cutting system complexity.

Z

Lower Flammability Risk (A2L Classification)

Classified as A2L, R1234ZE has lower flammability compared to A3 refrigerants and is considered safe when proper handling procedures are followed.

Applications & Use Cases

Automotive Air Conditioning

Many modern automakers are transitioning from R134a to R1234ZE because it maintains cabin comfort while drastically cutting the vehicle’s Carbon Footprint. Typical applications include:

OE installations in new passenger and commercial vehicles
Retrofit solutions for R134a systems (minimal component modifications)
Mobile service and maintenance: A/C recharge stations for auto repair shops

Commercial Refrigeration & HVAC Systems

R1234ZE shines in supermarket display cases, cold-storage warehouses, and light commercial HVAC:

Lower charge volumes reduce leak potential and operating costs.
Stable performance down to –20 °C makes it ideal for low-temperature freezing applications.
Popular among green-certified supermarkets, cold-rooms, and high-efficiency chillers.

Saturation Pressure & Boiling Point

Boiling Point (at 1 atm): –19.2 °C
Evaporation Pressure (0 °C): 1.2 bar (gauge)
Condensing Pressure (50 °C): 10.5 bar (gauge)

These thermodynamic properties ensure efficient heat transfer, enabling systems to reach desired cooling loads quickly and maintain stable performance under various ambient conditions.
