KLEA®407C

商標 Trademark：KLEA

簡介 Introduction：

所有R-407系列製冷劑均基於三種HFC製冷劑R-32，R-125和R-134a的混合物。 R-407C的配方與現有的HCFC製冷劑R-22非常匹配，可用於空調，製冷和製冷應用，並且是商業規模使用的首批R-22替代品。適用於翻新和原始設備使用。 KLEA®407C符合2030年以後的GWP要求，這是針對工業和商業製冷的歐盟F-氣體法規。
組成（wt％）R-32 / R-125 / R-134a = 23/25/52
請注意，並非所有產品在所有市場上都可用。

All of the R-407-series refrigerants are based on blends of the three HFC refrigerants R-32, R-125 and R-134a. R-407C has been formulated as a good match to the existing HCFC refrigerant R-22 for use in air conditioning, chilling and refrigeration applications and is the first of the R-22 alternatives to be used on a commercial scale. Suitable for retrofit and original equipment usage. KLEA®407C meets the GWP requirements beyond 2030 under the EU F-Gas Regulations for industrial and commercial refrigeration.
Composition (wt%) R-32/R-125/R-134a = 23/25/52
Please note that not all products are available in all markets.
