westinghouse air brake tech Generator Air Cooler

Generator Air Cooler

Cooling Solution for Mid/Lower Range Applications
Unifin is one of the world’s leading suppliers of equipment used for cooling new and existing air-cooled generator installations, from gas and steam to nuclear turbine power.
 
Electrical generators produce not only electricity but heat from electrical resistance (I2*R) and windage losses that are a byproduct of creating electrical power from rotating equipment. Unifin coolers remove this heat from the generator cooling air to the plant cooling water. These coolers are located within the generator or foundation and are an integral part of the overall heat removal system. Warm gas from the stator and rotor pass through the coolers, transferring heat to the fins and cooler tubes.
 
Known for their unmatched reliability, Unifin’s air generator coolers are designed and built to provide efficient power generation over the long haul.

wabtec westinghouse air brake tech Integral Fin Tube

Integral Fin Tube

It's What Makes Unifin Unique
Many of Unifin's cooling products incorporate integral finned tubing. This finned surface is formed as a thick walled aluminum tube and is put through cold rotary extrusion, forming fins that are much longer in diameter than the original tube.
 
This process hardens the aluminum so the fins are very strong, resulting in optimal heat transfer efficiency and exceptional durability. It can be applied to single aluminum tubes (mono aluminum) or with the addition of a liner tube within the original aluminum tube (bi-metal).
 
With bi-metal tubing, the fin material is always aluminum and the liner is usually copper-nickel, stainless steel or titanium, with the extrusion process creating a very strong mechanical bond between the two. The result is a rugged, reliable heat transfer surface with fins that do not break, unwind or become loose with subsequent loss of capacity.

Linear Sliding Contacts Rail Track wabtec Products

Linear Sliding Contacts

Used where current has to be transferred to mobile equipment through a rail or track, where linear speed is relatively low, but current density is high.
 
Strong, highly conductive, carbon materials with a very high copper content are produced in a variety of shapes. The complexity of shapes, together with the materials used and the quantities required, lend themselves to manufacture by pressing to finished dimensions from metallurgical powders.
 
Gerken has a standard range of components produced in this way and the capability to design and manufacture bespoke parts for customer requirements.

Lube Oil Coolers picture

Lube Oil Coolers

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.

Wabtec Unifin Motor Generator and Marine Coolers

Motor Generator and Marine Coolers

Removable Cover Plate Coolers
Unifin manufactures a wide range of RCP generator coolers, motor coolers and marine coolers with a unique optional leak detector feature for totally enclosed water air-cooled (TEWAC) applications.
 
All have been developed as heavy duty industrial quality cooling coils as distinct from lightweight ventilating or air-conditioning units. Although standardized in basic designs, they can be made with optional features and materials to suit exact customer requirements.
 
Leak Detector
 The unique leak detector configuration is a popular option for these installations. The leak detector system is designed to prevent catastrophic failure of the motor or generator should water leak into the cooling air, which dissipates the heat by sensing moisture before it can leak into the air.
 
The Unifin leak detector system consists of two bonded concentric tubes, each joined to a separate tube sheet.
 
This double tube construction provides double protection against possible leaks due to corrosion as well as tube barriers separating the tube side fluid and the air side.
 
Integral Finned Tubing
Many of Unifin's cooling products incorporate integral finned tubing. This finned surface is formed as a thick walled aluminum tube and is put through cold rotary extrusion, forming fins that are much longer in diameter than the original tube. This process hardens the aluminum so the fins are very strong, resulting in optimal heat transfer efficiency and exceptional durability.
 
This process can be applied to single aluminum tubes (mono aluminum) or with the addition of a liner tube within the original aluminum tube (bi-metal). With bi-metal tubing, the fin material is always aluminum and the liner is usually copper-nickel, stainless steel or titanium, with the extrusion process creating a very strong mechanical bond between the two. The result is a rugged, reliable heat transfer surface with fins that do not break, unwind or become loose with subsequent loss of capacity.
 
Plate Fin Coolers
Unifin offers Plate Fin Coolers for motor and generator cooling incorporating press-on fins, giving our customers an economical alternative to integral finned tubing which is used in the highest quality industrial cooling equipment. However, there are less demanding applications, where shielded motors/generators are used and press-on fins perform perfectly well.
 
Marine Coolers
Marine equipment must be especially rugged to withstand shocks and the corrosive environment of the sea. Unifin manufactures a special version RCP specifically designed for shipboard motors and generators operating in these adverse conditions.
