Original price was: $ 3,347.00.Current price is: $ 2,283.00.

The Thermal Transfer AOVH-20 3 Phase Motor Air-Oil Heat Exchanger, used to cool fluids, includes a 1/2 hp single phase 208-230/460 volt TEFC motor rpm 3450, 2 inch NPT, and can remove up to 17 hp of cooling with a maximum of 120 gpm in a single pass configuration.

Made in USA



The Thermal Transfer AOVH-20 3 Phase Motor Air-Oil Heat Exchanger is widely used in applications where water is not available for cooling fluids with a shell and tube heat exchanger. Going off of this, air cooled oil coolers are built for operation with maximum oil pressures of 300 PSI and temperatures of 400°F. The Thermal Transfer AOVH-20 3 Three Phase Air-Oil Heat Exchanger offers that motors furnished are specially built for fan duty. They are guaranteed by the manufacturer for operation in a maximum ambient temperature of 104°F. Consideration should be given to installation location so motors are not subjected to temperatures above this level. Air/oil coolers that are to be installed for utilization of waste heat for the space heating should be mounted 7 to 14 feet above the floor depending on the structure, for proper heat distribution. The Industrial AOVH Series is a high performance version of the AO Series that features high flow rates and higher heat rejection in a compact size. Included within the Thermal Transfer AOVH-20 3 Phase Motor Air-Oil Heat Exchanger, the series offers that the design includes a double core, a high performance fan and adjustable louvers that will allow the user to regulate the direction of heated exhaust air. The utilization of the High-Low Turbulator design yields high flow capacity with low flow pressure.
