Product Data
AIRCOL 228 Range
Synthetic Refrigeration Compressor Lubricant
Description
The Aircol 228 range of refrigeration oils is formulated from selected alkyl-benzene base stocks.
Application
Suitable for use in R22 refrigeration systems with very low evaporator temperatures where Alkyl-benzene based lubricants
are recommended by the manufacturer. These products may not be suitable for use in refrigeration systems employing
screw compressors due to the high level of solubility of refrigerant in the lubricant, which may reduce its viscosity to
unacceptable levels. However this is largely dependent on operating conditions.
Castrol Aircol 2284 can also be used in ammonia refrigeration compressors where an ISO VG 68 Alkyl-benzene based
lubricant is recommended.
Features / Benefits
The Castrol Aircol 228 range of refrigeration oils has excellent miscibility ａnd solubility characteristics with R22.
The very low floc points enable the Icematic 228 range to be used in systems where evaporator temperatures are
extremely low.

AIRCOL 228系列
合成制冷压缩机润滑油
描述
aircol 228系列冷冻油由精选的烷基苯基原料配制而成。
应用
适用于蒸发器温度很低的R22制冷系统，其中烷基苯基润滑剂
由制造商推荐。这些产品可能不适用于使用
螺杆式压缩机由于制冷剂在润滑油中的高度溶解性，可能使其粘度降低到
不可接受的水平。然而，这在很大程度上取决于操作条件。
Castrol aircol 2284也可用于氨制冷压缩机，其中ISO VG 68烷基苯基
建议使用润滑剂。
特点/优点
Castrol aircol 228系列冷冻油与R22具有良好的混溶性和溶解性。
非常低的絮点使Icematic 228系列能够用于蒸发器温度为
极低。
