Hydraulic Oil Cooling

Cooling Medium





Air Cooled / Copper Tube / Aluminum Fin

Mobile Air Cooled Copper Tube/Aluminum Fins

The Mobile AOHM, based off our AO Series, & AOVHM, based off our AOVH Series, features a wide flow range and high heat removal with a long life hydraulic motor drive.  This heavy duty construction is idea for mobile applications where the cooler can be remote mounted away from the engine’s heat to provide more efficient cooling.

As with the AO and AOVH these units can be configured for one or two pass flows for either low flow high heat rejection or high flow high rejection applications.  Both can be setup to include an internal pressure bypass for cold start-up protection.  The high/low turbulators allow for optimal heat rejection at lower flow rates.  Other features include a high-performance fan and adjustable louvers to regulate the direction of heated exhaust air.
