Compressor Oils
Capella® WF 32, 68
Description

Capella® WF is a high-quality essentially wax-free oil for the lubrication of compressors used in refrigeration and airconditioning systems. The product series are recommended for use with ammonia, carbon dioxide and halogenated refrigerants. Capella WF is manufactured from naphthenic base oils selected to meet refrigeration compressor manufacturers' requirements. The product series offers particularly good low temperature properties and high stability, minimizing varnish and sludge formation over extended operating periods. Capella WF is dehydrated and packaged to resist moisture.

Recommended Uses

Refrigeration compressor oil recommended for use with ammonia, carbon dioxide and chlorofluoro- and hydrochlorofluoro carbons (CFCs & HCFCs — freon) as well as sulfur dioxide and ethylene chloride refrigerants. Capella WF product series delivers very low freon floc and pour point performance and offers chemically stable performance in presence of ammonia and fluorinated hydrocarbons. For this they make an excellent choice for ammonia systems with the minimum evaporator temperature as low as –50°C (provided evaporator hot flush capability), and fluorinated hydrocarbon refrigerants with minimum evaporator temperatures of –45°C (R12), –35°C (R22) and –25°C (R502) respectively. For ammonia systems with minimum evaporator temperatures of –60°C, Capella A is recommended. For systems containing hydrofluoro carbon (HFC) refrigerants such as R134a, R404a, R507, etc., Capella HFC is recommended.

Performance Benefits

1. Efficient, Trouble-free Operation

Extremely low pour point and freon floc point (below –50°C) enable fluidity without wax or deposit formation at very low minimum evaporator temperature, even with low solvency of the lubricating oil in the refrigerant. This further contributes to evaporator efficiency and cleanliness of the flow lines. Low moisture content helps prevent icing in refrigeration expansion valves and delivers maximum corrosion protection.

2. Minimum Downtime

Robust thermal and oxidation stability protect against inservice oil thickening and minimize formation of harmful gum, varnish and sludge in the system, helping to ensure extended drain intervals.

3. Lower Maintenance Costs

Reliable lubricity helps protect against vulnerable component wear, reducing maintenance downtime and costs. The product is further compatible with a wide range of refrigerants, helping reduce inventories and potential misapplications.
