| Mechanical Filters |
ELC |
| Cannot effectively remove contaminants
below 10 microns |
Removal efficiency
exceeds 0.1 microns |
Low collection efficiency:
A filter holds 1/10th its weight in contaminants |
A collector holds twice its
weight in contaminants |
| High replacement cost |
Low replacement cost |
| High energy consumption to pump oil through filters |
Low energy consumption as
this is a kidney-loop system |
| Cannot retard oxidation / sludge formation |
Retards oxidation / sludge formation |
| Cannot prevent wear of pumps |
Prevents wear of all moving parts |
| Hydraulic parts like pumps, valves, oil seals require replacement inspite of using filters |
If ELC is dedicated, & oil temperature is controlled, life of components is indefinite |
| Machine efficiency reduces & cycle time increases as filters get choked |
Ensures stable cycle time |
| Cannot remove sludge |
Only system which efficiently removes sludge |
| Fine mesh, synthetic filters cause high volt electrostatic spark discharge cracking oil molecules. This also depletes oil additives |
Totally safe for oil. No harm to additives |
