KLEA®134a

商標 Trademark：KLEA

簡介 Introduction：

在大部分改裝和新設備的應用範圍中，R-134a被公認為最適合R-12的替代產品。與R-12在空調，高溫和中溫使用方面非常適合。它可用於超市的混合串聯系統，並用於某些HFO混合物中，以降低易燃性和提高效率。
請注意，並非所有產品在所有市場上都可用。

Widely accepted as the most appropriate alternative for R-12 over the majority of the application range for both retrofit and new equipment. A very good match to R-12 for air conditioning, high and medium temperature usage. It can be used in hybrid cascade systems for supermarkets and is being used in some of the HFO blends in order to bring lower flammability and better efficiency.
Please note that not all products are available in all markets.
