Portable Coalescers from Eriez Hydroflow are designed to be quickly and easily moved from machine to machine. They use an oleophilic (oil-attracting) coalescing plate-pack media to remove oils. The plate pack consists of more than 100 sq. ft. of coalescing area to maximize oil removal. The unit is equipped with a standard electric submersible pump. An optional air pump or a heavy-duty electric pump for deeper sumps are also available. The portable coalescer can also be used on high-temperature fluids such as heavy-duty cleaners.
Its portability enables a single unit to support tramp oil removal for an entire metalworking shop. The unit can also be made stationary to work on large sumps or central systems. Larger-flow-rate systems can also be custom engineered to meet user needs.
Excess tramp oil can lead to smoke, mist and bacterial infestation of metalworking fluids. It can also adversely affect surface finish and reduce tool and dimensional tolerance control, the company says. Installing the portable coalescer is said to extend the life of coolants and cleaners, improve machining operations and preserve valuable tools.
Standard features include adjustable feet for leveling, adjustable oil removal weir pipe, tank lid, floating oil collector to skim off oils and dirty fluid, pre-pump strainer and tank drain valve for cleaning. Options include self-priming centrifugal pump for pumping below ground sumps, 316-grade stainless steel tanks for high or low pH fluids, larger tank sizes and flow rates, and 110-V/50 Hz and 220-V/50-Hz operation.
