What types of hydraulic systems is the AOVH-5 best suited for?

The AOVH-5 is ideal for small to mid-sized hydraulic power units, lube oil systems, and machine tools that generate moderate heat. It is commonly used on compact hydraulic presses, tooling systems, and small gearboxes where a compact, fan-driven cooler can maintain safe oil temperatures without taking up a lot of space.

How do I decide between the AOVH-5 and the AOVHR-5-2 two-pass version?

Choose the standard AOVH-5 when you have relatively stable temperatures, moderate flow, and no concern about occasional higher backpressure. The AOVHR-5-2 is a better choice when you want extra cooling from a two-pass flow path and built-in protection from pressure spikes during cold starts or when oil viscosity is high. The AOVHR-5-2 also has a typical flow range of about 4–50 GPM, making it a strong option for more demanding circuits.

Can the AOVH-5 handle different oil viscosities or synthetic fluids?

Yes. The AOVH-5 is designed for common hydraulic and lubrication oils, including many mineral and synthetic formulations, as long as system pressure, temperature, and material compatibility are respected. When using heavier oils or operating at lower oil temperatures, viscosity correction factors should be used to confirm proper sizing and acceptable pressure drop.

What electrical requirements should I plan for when using the AOVH-5?

The standard AOVH-5 uses a TEFC fan motor of approximately 1/2 HP that is typically supplied for 115/208–230 V, single-phase, 60 Hz service. Always confirm the motor nameplate for voltage, phase, and full-load amps, and size the disconnect, fusing, and wiring accordingly. Other motor configurations may be available if different electrical requirements are needed.

How should the AOVH-5 be mounted and piped for best cooling performance?

For best performance, mount the AOVH-5 horizontally with unobstructed airflow through the finned core and adequate clearance around the fan and guard. Connect the oil so it enters the lower port and exits the upper port, and consider using flexible hoses to reduce vibration. Install the cooler in the return line or a dedicated cooling loop, and ensure that the system is clean and properly filtered to avoid fouling the tubes.

Description

For best results, mount the AOVH-5 horizontally with unobstructed airflow through the finned core and allow adequate clearance around the fan and guard. Pipe the cooler so flow enters the lower port and exits the upper port, using flexible hoses where possible to reduce vibration transmission. Install the cooler in the return line or dedicated cooling loop, and make sure the system is clean and filtered to prevent debris from clogging the tubes.
