R513A in brief
| Composition | A blend of R1234yf (an HFO) and R134a (an HFC) |
|---|---|
| Developed as | A replacement for R134a |
| ASHRAE safety class | A1: lower toxicity, no flame propagation |
| Ozone depletion potential (ODP) | 0 |
| Global warming potential (GWP) | 631 (IPCC AR4) or 573 (IPCC AR5) |
GWP compares the warming effect of one kilogram of a gas with one kilogram of carbon dioxide over 100 years. Two sets of values are in common use, from the fourth (AR4) and fifth (AR5) assessment reports of the Intergovernmental Panel on Climate Change. Always check which set a regulation or a data sheet refers to.
How it compares
| Refrigerant | Type | GWP (AR4) | Safety class | Flammability |
|---|---|---|---|---|
| R404A | HFC blend | 3922 | A1 | Non-flammable |
| R134a | HFC | 1430 | A1 | Non-flammable |
| R513A | HFO/HFC blend | 631 | A1 | Non-flammable |
| R290 (propane) | Hydrocarbon | 3 | A3 | Highly flammable |
R290 has the lowest GWP of the four, but it is highly flammable, which limits the charge allowed in an appliance and adds rules for transport, storage and service. R513A sits between: a GWP less than half that of R134a and about one sixth that of R404A, with the same A1 safety class as the gases it replaces.
Why we chose it for mobile equipment
- Non-flammable. Our active boxes travel inside vans, trucks and warehouses, next to other goods and often next to people. An A1 refrigerant keeps the safety case simple.
- Lower climate impact. High-GWP refrigerants are being phased down in many markets. A lower-GWP charge makes equipment easier to place on those markets and to keep in service.
- Familiar to service technicians. R513A works at pressures close to R134a, so tools and handling are familiar.
- No ozone depletion. ODP is zero.
Which Lemosun products use R513A
- LMS980 mobile low-temperature cold chain box, 980 L, −25 °C to +10 °C
- 12/24 V portable compressor car fridges, 20 L and 40 L
Our finned tube heat exchangers can also be built for R513A systems, as well as for R134a, R404A, R407C, R410A and R290.
A note on regulations. Refrigerant rules differ by country and change over time. Before you import refrigeration equipment, check the current rules in your market, or tell us the destination and we will state the refrigerant and charge on the quotation.
