Our KLEA range of HFCs (hydrofuorocarbons) was developed to replace CFCs and HCFCs in many refrigeration, air conditioning, aerosol and foam blowing systems around the world, and we are working to expand our range of refrigerants to include a range of lower GWP refrigerant options in order to provide customers with the benefts and characteristics they seek but at the smallest carbon footprint.

Effective and effcient refrigerant blends for every application:

KLEA 407A and KLEA 404A Ideal for supermarket refrigeration

KLEA 407C Developed for air-conditioning

KLEA 410A For effcient and compact A/C-units

While the transition from CFCs is essentially complete, alternatives to HCFC 22 for use in existing or new systems continue to be important, as HCFCs are phased-out. Mexichem Fluor offers a full range of HFC products to replace HCFC 22 in a range of applications and continue to explore new product offerings.

KLEA 134a Widely accepted as the most appropriate alternative to R-12 over the majority of the application range for both retroft and new equipment. A very good match to R-12 in air-conditioning, high and medium temperature usage.

KLEA 407A KLEA407A is an energy effcient, low GWP refrigerant designed for use in medium and low temperature supermarket applications. It is suitable for new installations and retrofts on existing R-22 units or R-404A units to achieve a lower GWP refrigerant.

Composition (wt%) R-32/R-125/R-134a = 20/40/40

KLEA 407C All of the R-407 refrigerants are based on blends of the three HFC refrigerants, R-32 (difuoromethane), R-125 (pentafuoroethane) 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 frst of the R-22 alternatives to be used on a commercial scale. Suitable for retroft and original equipment usage.

Composition (wt%) R-32/R-125/R-134a = 23:25:52

KLEA 410A A leading high-pressure alternative to R-22, comprising of R-32 and R-125, for air-conditioning and refrigerant applications.

Composition (wt%) R-32/R-125 = 50/50

KLEA 404A A long-term alternative to R-502 for retroft and refrigeration applications.

Composition (wt%) R-143a/R-125/R-134a = 44:52:4

KLEA 507 A long-term alternative to R-502, comprising of R-125 and R-143a, for retroft and refrigerant applications.

Composition (wt%) R-125/R-143a = 50:50

KLEA 508 Ideal for use in low temperature applications, such as biomedical freezing.

Composition (wt%) R-23/R-116 = 39/61

KLEA 23 An alternative for ultra low temperature refrigeration applications.

KLEA 32 Of interest as a blend component for R-22 and R-502 alternatives. In many ways R-32 can be regarded as a non-toxic, non-corrosive, high-capacity ammonia, as far as its refrigeration characteristics are concerned. Like ammonia, its high compressor discharge temperatures require the use of appropriate compressor technology.

美希氟化工所生產的KLEA品牌HFCs系列（氫氟烴）產品，用于替代制冷、空調、氣霧劑與發泡等諸多系統中的CFCs與HCFCs；同時也在開發一系列低全球變暖潛能值的制冷劑，以滿足用戶在實現碳排放最小化的同時、達到更多的優勢和特點的要求。

廣泛適用的高效制冷劑：

KLEA 407A與KLEA 404A適用于超市制冷

KLEA407C適用于空調系統

KLEA 410A適用于高效、緊湊型空調器

盡管 CFCs的替代已基本完成，HCFCs的替 dai huan 在進行，如何替代現有系統或新系統中的HCFC 22依然是重要的課題。美希氟化工已針對各種應用開發出全系列的HFC產品以取代HCFC 22，并在繼續開發新的產品。

KLEA 134a 該制冷劑為R-12最合適的代替品，可用于大部分改裝設備或新設備。在中高溫應用的空調系統中與R-12性能相當。

KLEA 407A 是高能效、低全球變暖潛能值的制冷劑，適用于中低溫范圍的超市制冷系統。無論是用于新設備、或 R-22設備及R-404A設備的改裝，可達到低全球變暖潛能值。

組份比 (wt%) R-32/R-125/R-134a = 20/40/40

KLEA 407C 所有R-407制冷劑均由R-32(二氟甲烷)、R-125(五氟乙烷)及R-134A這三種HFC制冷劑混配而成，可替代現有的HCFC R-22用于空調、冷凍與制冷系統，而且是 shou ge R-22的商業代替品。適用于改裝設備和新設備。

組份比 (wt%) R-32/R-125/R-134a = 23:25:52

KLEA 410A 主要的R-22高壓系統的替代品，由R-32及R-125構成，適用于空調與制冷系統。

組份比 (wt%) R-32/R-125 = 50/50
