Descrizione
Heat is the quiet thief of hydraulic systems. Oil that runs twenty degrees too hot loses viscosity, loses film strength, and starts to take the pump and the seals with it. Nothing in the circuit announces the problem until a valve sticks or a hose hardens. A cooler is not an accessory bolted on for safety; it is the part that decides how long the rest of the circuit lives.
The AW0607T is a forced-air oil cooler built around a finned aluminium core and a 170mm fan, rated at 680 kcal per hour of cooling capacity with 200 cubic metres per hour of discharge air. Those two figures are the ones to size against, because capacity without airflow is a number on a page. The core carries the oil, the fan pushes ambient air across the fins, and the difference between inlet and outlet oil temperature tells you whether the unit is matched to the duty or merely present.
The electrical options are what make it usable across markets rather than on one bench. The same body is supplied with an AC 220V fan, an AC 380V fan, a DC 12V fan or a DC 24V fan, which covers a machine running from mains in a plant and a vehicle or mobile rig running from a battery. The hydraulic side stays constant: the oil circuit is independent of the fan supply, so the cooler can be wired to whatever the installation already provides.
Installation is the part that decides whether the unit performs. Mount it where the fan pulls cool ambient air and discharges away from the machine rather than into a hot cabinet, keep the oil lines short and unrestricted, and put the return to tank downstream of the cooler so the reservoir is not being heated by what the cooler just removed. Vibration isolation matters on mobile equipment, and a clean fin stack matters more than most owners expect, because a clogged core loses capacity long before it fails.
A hydraulic system does not die of pressure. It dies of the heat nobody measured.
Key Features
- 680 kcal/h cooling capacity Rated on the core, not on a best-case airflow figure, so the duty point can be matched to the circuit.
- 200 m3/h discharge volume A 170mm fan moving enough ambient air across the fins to keep the core working at its rating.
- Four fan supply options AC 220V, AC 380V, DC 12V and DC 24V bodies, so one design covers plant and mobile installations.
- Finned aluminium core Oil passages in an aluminium matrix, which is where the heat actually leaves the circuit.
- Independent oil and fan circuits The fan is powered from whatever the machine supplies; the hydraulic loop is unaffected by that choice.
- AW0607 series platform A known model number, so replacements and spares follow the same mounting and port pattern.
- Compact 170mm fan envelope Fits inside machine cabinets and behind guards without a remote cooler assembly.
- Serviceable fin stack Accessible for cleaning, which is the single most neglected maintenance item on any air-blast cooler.

Where It Belongs
This is the cooler for the hydraulic power pack in a machine tool, the press, the injection unit, the mobile lift or the test rig that runs all day in a warm workshop. It suits the retrofit where an existing circuit has started running hot and the cabinet has room for a 170mm fan body. It also suits the OEM building a power pack for export, where the same cooler has to be orderable with a 220V fan for Europe and a 24V fan for a vehicle without redesigning the mounting.
Frequently Asked Questions
Q: Which fan voltage should I order?
A: Whatever the installation supplies. Mains-fed plant cabinets usually want AC 220V, three-phase cabinets AC 380V, and vehicle or battery installations DC 12V or DC 24V. The oil side is identical across all four.
Q: How do I know if 680 kcal/h is enough?
A: Measure the oil temperature at the tank under real duty and compare it with the oil grade's working range. If the circuit runs more than about 15 degrees above ambient, the cooler is undersized for the load rather than faulty.
Q: Where should it be mounted?
A: Where the fan can pull cool ambient air and discharge it away from the cabinet. A cooler mounted in a sealed enclosure recirculates its own heat and looks like a failed unit.
Q: Does it come with hoses or fittings?
A: The cooler is supplied as the unit. Hoses, fittings and mounting hardware depend on the installation and are chosen by the builder to match the circuit.
Q: Can it be used with fluids other than hydraulic oil?
A: It is built for hydraulic oil. Water-glycol and coolant circuits need a different core and different seals, so ask before substituting a fluid.
Q: How often does the core need cleaning?
A: More often than most service schedules admit. In a machining environment, blow the fins out monthly; in a clean plant, at every oil change. Capacity falls gradually and silently as the fins load up.
Q: What if the fan fails?
A: Replace the fan, not the cooler. The core and the fan are separate parts on this platform, and a fan swap is a fraction of the cost of the assembly.
