Turbine Oil Coalescing Systems

Improved Oil Processing with Low Maintenance System

Velcon Filters has over 50 years experience designing and manufacturing coalescing filtration equipment. The TOC Series units combine the latest coalescing technology with the finest available microglass filter media to restore turbine lube oil to an exceptionally clean and dry condition. The units can be used to upgrade or replace older, low efficiency reservoir filtration systems.

PERFORMANCE

• Restore oil to an ISO cleanliness of 14/11 or better
  
• Continuously remove free water down to 150 ppm
  
• Prevent system sludging and premature oil degradation
  
• Field test data available on request

SIMPLICITY

• Compact, one button operation for round-the-clock service
  
• No adjustment needed for varying contaminant inlet levels
  
• Prefilter extends life of specialized coalescing elements
  
• One-page operation summary, components labeled to match gauges

RELIABILITY

• Rugged ASME design vessels assure safe, leak-free service
  
• Heavy-duty Viking pump is factory coupled for years of maintenance free service – there are no other moving parts
  
• Magnetic starter with overload protection
  
• Complete system is factory hydro-tested and operated before shipping

HOW IT WORKS

The TOC Series Turbine Oil Coalescing Systems remove water and dirt from turbine lube oil. Contaminants are removed in stages (see photo) A, B, and C:

A. Particulate solid contaminants are removed in the Pre-Filter stage (#8 in diagram below) by cost effective, high surface area pleated synthetic media cartridges. This extends the life of the specialized filters downstream.

B. Free and emulsified water are removed in the Filter/Separator stage (#10 below). Finely dispersed water passes through the coalescer element and grows into larger drops. These drops collect in the vessel sump where they are drained. A Teflon® coated screen separator prevents any small water drops from entering the effluent oil stream. Fine particulate solid contaminants are also removed by the coalescer elements.

C. The final Polishing stage (#14 below, optional on TOC10) uses synthetic media elements to remove fine particles.
