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.

It has been designed to replace R-404A in new and existing installations, for medium and low temperature commercial and industrial refrigeration applications. It is suitable for supermarkets and hypermarkets including centralised pack systems, chill and frozen cold stores, and refrigerated transport. It can be used as a replacement for R-22 in some Dx applications, but must be in accordance with conversion guidelines. Commercial specifications Composition: 26 % R-32 - 26 % R-125 - 21 % R-134a - 20 % R-1234yf – 7 % R-1234ze (±0.5 %-2 % / ±2 %-0.5 % / ±0.5 %-2 % / ±2 %-1 % / ±0.5 %-2 %). Purity: ≥ 99.5 % weight. Water content: ≤ 10 ppm weight. TChlorine 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 application and the most suitable for your application. Regulation The use and implementation of R-448A are governed by the European Regulation N° 517/2014. The recovery of R-448A is mandatory under the European Regulation N° 517/2014.
