XeteX, Inc. Customized Cooling of Electrical Equipment DXC-850

Building ventilation is not the only application for energy recovery. XeteX works with industrial OEMs to design custom solutions for process heating and cooling. This unit was developed to provide cooling for industrial-scale variable frequency drives used in coal mining. The XeteX unit replaced mechanical cooling and achieved the desired cooling at one tenth the operating cost, resulting in a pay-back period of just a few months. Requiring no changes to the original drive equipment, these units were designed to bolt directly onto the existing drive cabinets. The highly efficient, double-pass heat exchanger removes 76.9 kW of heat even under the worst hot summer conditions while consuming only 6.67 kW of fan power. The fully sealed, epoxy coated heat exchangers withstand the corrosive industrial environment and maintain the required clean-room quality air used to cool the drive equipment. The primary and redundant blowers were wired to interface with the pre-existing VFD controls making the XeteX unit a plug-and-play system.
