Carnet Bleu 2018_EN_BD / Das blaue Heft

Blue Handbook- "Blaues Heft" - 2018 In dieser Übergangszeit werden neue Kältemittel entwickelt, um jene mit hohem GWP zu ersetzen. Darum wurde soeben das Blue Book, dieses für alle Kältemittelbenutzer unerlässliches Tool, neu herausgegeben.

Commercial specifications Composition: (59 % R-125 – 30 % R-1234yf – 11 %R-32) (±1.8% / ±0.1%- 1% / ±1.7%). Purity: ≥ 99.5 % weight. Water content: ≤ 10 ppm weight. Chlorine ion test (silver nitrate test): negative. Total Acidity (HCL): ≤ 1 ppm weight. Non-condensable content (gas phase): ≤ 1.5 % volume. Oils Use a polyol ester (POE) oil. Consult Climalife regarding the viscosity of the oil selected for your system and the most suitable for your application. Regulation The use and implementation of R-452A are governed by the European Regulation N° 517/2014. The recovery of R-452A is mandatory under the European Regulation N° 517/2014. (Refer to regulations enforced in each country). HFC/HFO R-452A 124
