Designed and Built for High Performance
Unifin is one of the world’s leading suppliers of equipment used for cooling new and existing hydrogen-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 hydrogen cooling gas to the plant cooling water. These coolers are located within the generator frame 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 hydrogen generator coolers are designed and built to provide efficient power generation over the long haul.
