3 Application ranges
• BSE32: Basic viscosity 32 cSt at 40°C. Stationary
refrigeration and air conditioning systems with con-
densing temperatures up to 70°C.
• BSE55: Basic viscosity 55 cST at 40°C. Mobile refri-
geration and air conditioning systems with condens-
ing temperatures > 70°C.
• R22: see chapter Use of polyolester oils with chlorin-
ated (H)CFC refrigerants (R22 etc.), page 7. Other
replacement refrigerants for R22, their application
ranges and recommended oils can be found in the
Technical Information KT-651.

4 Properties of the BITZER polyolester oils
Information
The listed oils are categorized as group KD ac-
cording to DIN 51503, Part 1. To determine the
used condition of the oil, e.g. with respect to wa-
ter content or total acid number (TAN), the refer-
ence values of the standard DIN 51503, part 2,
apply.
