  Gregoriou Brothers Refrigeration Since 1979 Frosty-Freeze R515b, 10 Lbs., Refrigerant, Professional Check Charge-It Kit Please use the R134a scale for R515b as the temperature/pressure relationship is similar. R515b (HFO) 10 Lb. NO-HFC's ASHRAE EPA Approved Drop-in 134aReplacement (1) 10 Lb., Factory Sealed Can of R515b HFO, Drop-In Replacement for R134a which is a HFC in the Commercial Refrigeration Industry.   * The can has a top-mount, on/off valve with a 1/4" male flare hose connection.   (1) R515b Equipment sticker required by EPA to be placed on the unit showing the new R515b refrigerant is in the system.   HFC-134a (also called R-134a) R22, HCFC and HCFC-142b are the next two HCFCs that the United States will phase out.   The schedule to phase out HCFCs is: January 1, 2010 Ban on production, import and use of HCF 134a, R22, R404a and HCFC-142b, except for continuing servicing needs of existing equipment.   January 1, 2020 Ban on remaining production and import of HCFC HFC refrigerants.    January 1, 2030 Ban on remaining production and import of all HCFCs. On January 23rd 2023, our community began to remove all R134a, R22, R404a R410a listings from the site.    We have happy to be able to offer a new refrigerant, R515b "HFO" which is not a HFC.   R515b is a "HFO" and is Environment friendly !   R515b is the LOWEST GWP and the Only NON-FLAMMABLE Retrofit Replacement Refrigerant for R134a in commercial Refrigeration applications.   R515b has an ASHRAE designation of R-515b and is now available in the United States.     This revolutionary refrigerant is the #1 retrofit replacement for R134a in Commercial Refrigeration Applications.   R515b is the LOWEST GWP and the Only NON-FLAMMABLE Retrofit Replacement Refrigerant for R134a in commercial refrigeration applications.   (1) R515b (HFO) 10 Lbs.   ****R134a is History!!!!!, Make the change now.   R515b Contains "NO-HFC's"   A1-ASHRAE Certified   EPA SNAP Approved   R134a Replacement in Commercial Refrigeration Applications.   Coolers   Freezers   Walk-In Coolers and Freezers   Chillers   Air Conditioning Units that use R134a   Can R515ba be added to systems containing R134a without materially affecting the performance of the whole system?   First and foremost, the EPA does not condone, recommend or approve of mixing any refrigerants.   *Mixing of refrigerants is allowed in other countries however!   However, R515b does not form an azeotropic mixture with R134a.   Therefore, if a technician inadvertently or unknowingly adds R515b to a system containing R134a the system will not generate any higher pressures and will operate as normal without any harm to system components.   *True Drop-In Replacement for R134a in commercial refrigeration applications   *No Oil Changes   *No System Changes Required   *Made in the USA   The only refrigerant we use for all R134a commercial refrigeration  applications!   R515b is the LOWEST GWP and the Only NON-FLAMMABLE Retrofit Replacement Refrigerant for R134a in commercial refrigeration applications   R515b has an ASHRAE designation of R-515b and is now available in the United States.      The refrigerant does not require design modifications or component changes.       Clearly label the system to show it contains R515b, Equipment label is provided in the listing.   1) Ensure the right equipment is available (e.g., recovery unit and cylinders, container for recovered lubricant, vacuum pump, weighing scales, replacement drier, etc.)   2) Record baseline data to establish the normal operating conditions for the equipment   3) Check the manufacturer’s specifications for the unit to find the recommended R1334a charge in order to determine the amount of R515b to add.   4) Replace the filter/drier if moisture is suspected in the system. This is not necessary on a sealed system.   5) Having evacuated the system, liquid charge the unit with R515b up to 90% of the original charge amount of R134a and then compare to baseline data.   6) Switch on the unit and compare the baseline data, monitor sight glasses, suction line pressure and temperature, and discharge temperature; add additional R515b up to the recommended R134a system charge amount as needed.   7) Check system thoroughly for leaks; and repair as needed.   8) Clearly label the system to show it contains R515b.  ****You will receive a label with the refrigerant.   Switch on the unit and compare the baseline data, monitor sight glasses, suction line pressure and temperature, and discharge temperature; add additional R515b up to the recommended R134a system charge amount as needed.   * GWP: 299 IPCC 5th Revision * Application: R134A Replacement in Medium Temp Refrig
