GEI Industrial Systems Limited

The inner tube made of Cupro-nickel material is expanded into outer tube sheet facing the water surface. The outer tube which is press fit on the inner tube is of copper material have and longitudinal grooves along the length on the inner side circumferentially. The outer surface of these tubes have integral low fins for enhancement of heat transfer on the oil side and is expanded into the inner tube sheet.

The leaked water is collected in the recess provided between the outer and inner tube Sheet. Once filled, the water is sensed by the water leakage probe provided at the bottom and signal / alarm is indicated on the controller unit mounted on the shell of the cooler. The leaked water can then be drained out from the drain plug. This feature ensures safety to the transformer unlike the conventional oil cooler where oil and water mixing takes place in the event of leakage.

A feed water heater is a shell-and-tube heat exchanger. GEI designs and manufactures both low pressure heater and high pressure heaters which serves power plant up to 150mw rating. Feed water heater may be constructed suitably for horizontal or vertical installation, depending on the plant design requirement. The physical and thermal characteristics are vastly different for low and high pressure feed water heaters. Each feed water will contain from one to three separate heat transfer areas or zones including the de-superheating, condensing and sub-cooling zones. we offer admiralty brass / stainless steel tubes LP-heater and stainless steel tubed HP-heaters.

Feed water heater are designed as per the stringent requirement of international standards like ASME Boiler and Pressure Vessel Code, HEI standard for closed feed water heater, TEMA and IBR, as applicable.
