Oil Cooler Solves Overheating Problems

Jan. 30, 2009

Noren HyTec Oil Coolers have been tailored for hydraulic elevators, solving a variety of symptoms related to the overheating oil.

HyTec Coolers use heat pipe technology. Heat pipes move heat about 1000 timesfaster than solid copper, and have no moving parts. Noren heat pipes last 30 years with no maintenance or degradation in performance. Aluminum fins are attached to up to 12 individual 5/8" heat pipes, creating a matrix structure resembling a radiator. These structures are called cores. They measure 2" thick by 7 1/2" wide and range in length from 44" to 53". HyTec cores are inserted directly into the reservoir, and held in place by a metal enclosure. As hot oil from the return line flows into the reservoir, it is captured, and passes through the cores. This enables the heat pipes to extract heat from the oil and transport it to the top of the core -above the tank. Common fans are mounted atop the cores and draw ambient air through the heat pipe/fin matrix to remove heat from the system.
