From petrochemical to military and aerospace, 24 industries in all. Each contaminates oil differently.
Fire-resistant fluid in the captive power station, water-flooded oil-film bearing oil, emulsified hydraulic oil, varnish film in the rolling line. Each needs its own route.
Fire-resistant fluid / varnish
Captive power station fire-resistant fluid
A steel plant captive power station had a varnish film index well over the limit, reaching 66.7. After treatment on the nano-screening purification equipment, the measured index was 26.
Water / oil-film bearing oil
Oil-film bearing oil flooded with water
In September 2020 a steel plant trialled one nano-screening unit. Before it went in, water content in the tank stood at 7%. On the day it was commissioned it separated 200 litres of water; after a second ingress, more than a tonne was drawn off over six days.
Cleanliness / hydraulic oil
Emulsified hydraulic oil in the southwest
A steel plant in the southwest had water ingress emulsifying the hydraulic oil. One pass on the nano-screening purification unit brought the contaminated oil to NAS 7.
Fire-resistant fluid / long-term control
Fatty-acid-ester fire-resistant fluid
A steel plant in the northeast had fatty-acid-ester fire-resistant fluid emulsifying from chronic water ingress year after year. After treatment on the nano-screening purification equipment, water content was held at 800 ppm over the long term, which meets the production standard.
A power plant ran No.46 turbine oil with a damaged shaft seal taking in water at 20 kg per day. The oil was heavily emulsified and the unit was at risk. It was handled online — the nano-screening equipment running alongside the system rather than taking it down — and the water content in the outlet oil was held stable throughout.
A shaft seal that admits 20 kg of water a day is a mechanical defect; the oil is only where the water ends up. The set cannot be stopped while the seal is repaired, so the equipment sits beside the running system and holds the oil between services rather than restoring it once.
Where the objective is to return discoloured oil to service rather than keep running oil clean: lithium film production oil, collected waste engine oil, a crankshaft maker's hydraulic station, and vacuum pump oil at an appliance plant. The first two run on decolourising; the other two on purification.
Lithium film / decolourising
Lithium film production oil
A producer put its oil through the nano-screening decolourising purification system and the oil met the purification and regeneration target.
Waste-oil reclamation / decolourising
Collected waste engine oil
A waste-oil disposal company collecting engine oil from service stations ran it through the nano-screening decolourising system, and the result met the purification and regeneration target.
Machining / cleanliness
Hydraulic station at a crankshaft maker
The hydraulic station at a crankshaft producer was reading far above the contamination limit. After treatment on the nano-screening purification equipment the measured figure came back at NAS6.
Appliances / vacuum pump oil
Vacuum pump oil at an appliance plant
Vacuum pump oil at a domestic appliance producer ran over its water limit often enough that the oil was changed out repeatedly. After treatment on the nano-screening purification equipment the cleanliness reached NAS3 and the water content came down to 39ppm.
A steel plant in the southwest had Mobil 525 oil-film bearing oil take in a large quantity of water. On the nano-screening purification equipment, 2.2 tonnes of water was separated out within a single day. At that rate the oil cannot simply be replaced; the water has to be taken out of it.
How viscosity picks the model. Viscosity is the one criterion that maps directly onto model codes: 220 cSt industrial gear oil and oil-film bearing oil go to the FM-100/150DP-B, the same oils above 320# to the FM-100/150DP-C, and the economy FM-60DP-B is sized for an oil station of 5 m³.
Online or offline operation, fluid type, hazardous-area classification, and whether the oil is running or being recovered. These narrow the range before throughput does.
Oil name, kinematic viscosity, current cleanliness and water content, whether the system can be taken offline, and the target. With those we can name the route - vacuum, membrane, centrifugal or electrostatic - or say that no unit is needed.
