Last week we introduced the BUSS.  This week, its the TOS - Tramp Oil Sucker.  Number 1 on the list of life shortening contaminants in Metalworking Fluid is tramp oil.  You always see that ugly tramp oil layer covering the top.  In some places, newspaper is still being used to skim it off. Here is something that can help.  The Phasep tramp oil removal system from LNS America has a floating pick-up skimmer for the tramp oil and coolant mix from the top of the machine sump. As the liquid moves through the patented steel coalescing plates, oil droplets as small as 20 microns are separated from the coolant and rise to the top of the PhaSep unit. When the oil layer builds up sufficiently in the unit, it passes over a specially-designed weir, and is trapped away from the clean coolant. The oil can then be removed periodically through the waste oil drain. LNS America claims to clean of 99% of contaminated oil. Nice looking machine.
