ZP-260 sorbent¹A sorbent is a material used to absorb or adsorb liquids or gases. cartridges are designed for drying²The drying process should be carried out to remove water from zeolite. of lubrication³Lubrication is the process or technique of using a lubricant to reduce friction and/or wear in a contact between two surfaces. and electrical insulation oils⁴Insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties. by zeolite⁵Zeolites are microporous, aluminosilicate minerals commonly used as commercial adsorbents and catalysts. or other adsorbents. The unit is equipped with hatches for quick sorbent loading and unloading.  The cartridges of the ZP-260 unit can be filled not only with zeolite, but with other adsorbents, such as Fuller’s earth⁶Fuller’s earth is any clay material that has the capability to decolorize oil or other liquids without chemical treatment. or silica gel⁷Silica gel is an amorphous and porous form of silicon dioxide (silica), consisting of an irregular tridimensional framework of alternating silicon and oxygen atoms with nanometer-scale voids and pores., making the unit suitable for oil regeneration⁸Oil regeneration – is extraction of contaminants from oil in order to restore its original properties to be used equally with fresh oils. and acidity⁹Acid value (or neutralization number or acid number or acidity) is the mass of potassium hydroxide (KOH) in milligrams that is required to neutralize one gram of transformer oil. reduction.
