Lochinvar Corp.'s Copper-Fin Car Wash Bay De-Icing Systems are easy to install because each system comes engineered and assembled, complete with all piping to meet specific applications. The circulating pump, air separator, charged expansion tank and all controls are mounted and wired or easy installation and connection to utilities. The space-saving design of the Copper-Fin leaves more space in the mechanical room, and the Multi-Stack frame allows two units in the footprint normally required for one. The unique copper tube design uses a two-pass heat exchanger. Water is circulated through a row of highly efficient finned copper tubes, creating a scouring action that prevents sediment and lime scale build-up. The high heat transfer ratio of the finned copper tubing, combined with the high velocity water flow, offers a virtually instantaneous response to the demand for more heat. Lochinvar Corp.
