Total Lunaria SH 68

Full-synthetic PAO-based oil for ammonia (R 717) refrigerating compressors.

High resistance to oxidation in the presence of ammonia. Base oils and activation systems are specially selected to avoid the formation of black sludges (reaction between oil and ammonia).

Low pour point, eliminating the risk of any residual lubricant freezing in the evaporator, thereby providing excellent heat exchange.

Very high flash point given the low volatility of LUNARIA NH oils: oil consumption is reduced by 30 to 50 % compared with conventional oils.

Good compatibility with common elastomers (chloroprene, NBR….).

Warning: storage must be done in order to avoid the presence of water within the oil. Indeed, water could block the evaporator.

• Lubrication of refrigeration compressors (reciprocating and screw) using ammonia as a refrigerant.
• PAO (polyalphaolefin) base oils improve oil drain interval and ensure good performances even at very low temperatures.
• Field of application: evaporator temperature down to -50°C

Total Lunaria SH 68 Refrigeration Compressor Oil Product Advantages:

Before using the product, the vehicle’s maintenance guide should be checked. Oil changes should be carried out in accordance with the manufacturer’s recommendations. The product should not be stored at temperatures over 60°C. It should be kept away from sunlight, intense cold and extreme temperature fluctuations. If possible, the packaging should not be exposed to the elements. Otherwise, the drums should be laid horizontally to avoid any contamination from water and to prevent the product’s label from rubbing off.

All packages should be stored under cover. Where outside storage is unavoidable drums should be laid horizontally to avoid the possible ingress of water and damage to drum markings. Products should not be stored above 60°C, or exposed to hot sun or freezing conditions.
