Bearing Cooling Solutions
Rotating power generation equipment relies on sleeve bearings to align their shafts. Heat, generated through friction, is picked up by the lubricating oil used in these bearings and needs to be removed. Unifin’s Shell and tube lube oil coolers work nicely to perform this function. These coolers may contain bare tubes or “low fin” tubing typically of a non-ferrous material while the shells, baffles and header parts are usually ferrous material.
Over time these units become fouled on the inside of the tubes as well as the exterior making cleaning and maintenance an important commitment to satisfactory cooler life. Typically these units need to be replaced after about 25 years for service depending on type of cooling water. Unifin has just the replacement solution you need.
