Gas R410A 11.3 kg in Rechargeable Cylinder The rechargeable cylinder is included in the price and remains your property. R410A is the internationally preferred solution for new air-conditioning systems, heat pumps, and similar applications. Unlike R-22, R410A operates at much higher pressures and is compatible exclusively with POE synthetic oil. A major advantage of R410A is its significantly higher cooling capacity up to 50% more than R-22 allowing for smaller, more compact system components. It is important to note that components such as copper pipes, valves, and compressors must be designed to withstand the higher pressures of R410A. Due to these higher operating pressures, R410A is not suitable for retrofitting existing systems that use R-22. For such conversions, R-424A or R-407C are recommended as direct substitutes. Key Features: Ozone-friendly with ODP = 0 Exclusively compatible with POE synthetic oils Can be recharged in the event of leaks Higher cooling capacity and working pressure than R-22 GWP (Global Warming Potential): 2088 Boiling Point (at 1.013 bar): -51.58C Glide (temperature range): 0.1C Saturated Vapor Density at 25C: 61.5 kg/m UN Number: 1078 Safety Classification: A1 (Low toxicity, non-flammable) Must be loaded in the liquid phase

Freon Refrigerant - NU-22B 25lb (R-22, R-422D, R-407C, R-417A Replacement) If your system currently uses R-22, R-407C, R-422D, or R-417A, NU-22B offers an eco-friendly, direct replacement with no retrofit or oil change required. Simply evacuate the old refrigerant and recharge with NU-22B. Key Features Seamless Replacement: No retrofit required, making it simple to switch to NU-22B. Ease of Use: Just evacuate the existing R-22 and replace with NU-22B, suitable for both new and existing R-22 residential and commercial air conditioning systems, as well as non-flooded evaporator chillers. Note: Cannot be mixed with R-22; a complete evacuation is required before recharging. Why Choose NU-22B? Performance: Closely mimics R-22 operating characteristics, offering high performance for OEM and service replacement needs. Compatibility: Works with all standard oils, equipment, and materials used in R-22 systems no need for specialized tools or supplies. Safety: Classified as non-flammable and non-toxic (ASHRAE A1) with zero ozone depletion potential (ODP), making it a safe and responsible choice. NU-22B Facts: ASHRAE designation: R-422B Safety Classification: A1 Zero ODP (ozone depletion potential) Higher capacity than R-417A at R-22 operating pressures NU-22B has proven its reliability in thousands of installations worldwide, giving you the confidence of quality and safety. !!!!!!!!!!!
