The Castrol Aircol™ LPT Range (previously called Energol™ LPT) are refrigeration compressor lubricants formulated from highly refined naphthenic base oils for use in both large and industrial and small domestic refrigeration units.
The Aircol LPT range is formulated to function as lubricants and coolants, as well as sealants in refrigerating compressors.
They maintain good lubrication properties at the high temperatures reached during the compression phase and good fluidity at the low temperatures within the evaporators. Excellent lubrication of the moving parts in the compressor as well as recycling of the oil, entrained into the system by the refrigerant, are therefore ensured.
The chemical stability of the Aircol LPT oils prevents them from reacting with the refrigerants used in refrigeration systems to form potentially disruptive breakdown products. All Aircol LPT grades are suitable for use in systems using Ammonia (NH3) or halogenated hydrocarbons. They can also be used where good low temperature flow properties are required in the lubricant.
The Aircol LPT Range oils ensure long and trouble-free operation of refrigeration systems through a combination of:
