R513a refrigerant is an azeotropic (constant boiling point) blend of R134A and R1234yf that’s used for retrofit on R134a. It’s basically a refrigerant mixture of HFO with low Global Warming Potential (GWP) of 630. It’s also known as Opteon XP 10 in the market and is available as an alternative that works on latest technology, Trane Ilamda Synthesis. This alternative is available in the markets of North and Latin America since June 2015.

This new refrigerant by Dorin is used in place of R134a in refrigeration applications with medium and high temperature. Dorin has launched these refrigerants recently after careful and external tests that authenticate the efficiency, economy, and the installation capabilities of the 4HFO mixtures in the current plants. Dorins is known for high-quality products made in Italy industry since 1918, and due to the high degree of customization of the products.

R513a refrigerant is perfect to be used in new systems as well as for retrofit of current systems. These are available in 300kW to 1500kW capacities featuring a condenser circuit micro-channels, flooded evaporator, air vents and EC fans. It’s a non-flammable, super-efficient and a low GWP back-up refrigerant that lowers the direct refrigerant GWP by 56 percent. It’s clearly the best choice among all A1 categorized F-gases as it helps lower the carbon footprint of the current reefer containers.

What Affects GWP?

While making its way to the environment via leakage, a refrigerant affects the global warming levels by its power to reflect radiative heat from the earth. This capability is further affected by the molecular structure and also, its lifespan in the atmosphere and is attributed to a natural substance like CO2.

On the contrary, fossil fuels are used to charge reefers on a container and CO2 released into the atmosphere also has an effect on global warming. Thus, due to the incompetent systems consuming more energy, more CO2 is generated. TEWI blends the discharge of both the refrigerant and the power usage.

Features and Benefits

  • A great alternative to R134a, with corresponding physical and thermodynamic characteristics.
  • Azeotropic refrigerant mixture consisting of R1234yf and R134a.
  • For precise constitution, refrigerant must be loaded from the liquid phase
  • AGas refrigerant cylinders feature valves with dual port, making it easier for the withdrawal of liquid.
  • Non-flammable licensed with safety ranking of A1.
  • Compressors need to be loaded with polyolester oil. For this you must get in touch with the compressor manufacturer for more details.
  • Comes with low GWP of 631 which is 56% lower as opposed to R134a.
  • Performance is almost like that of R134a
  • Can be utilized as a retrofit or in new installations.

Meet the Following Requirements Wile Using R513A

  1. Keep up with sufficient superheat settings so that a minimum level of suction superheat of 8K is maintained.
  2. Avoid leaking of any liquid refrigerant into the compressor at any given time. This should specially maintained when it’s at standstill, during or after the process of defrost, or post the reverse mode such as, the ones in heat pumps.
  3. Make sure to pump down.
  4. It’s mandatory to use a crankcase heater.
  5. Installation to R450A and R513A refrigerant is permitted for compressors that are sanctioned for these refrigerants.
  6. Emerson Climate Technologies suggests using suction accumulators for R450A and R513A refrigerants, except it has been certified that an accumulator is not required.

So, rely on trusted manufactures like Dorin with years of experience for your R513A refrigerant requirement, and support the work of your customers and users.
