Cooling of hydraulics circuits

The HY series of compact cross-flow air-oil heat exchangers by Oesse are used for cooling hydraulic circuits installed on industrial plants and mobile machinery.

The manufacturer explained that these heat exchangers meet the demands of different applications thanks to different options available: they can use the available fan unit type: AC (single phase, three phase, with B14 electric motor) or DC (12V and 24V) and are designed for hydraulic motors type GR2 and GR3. The series is composed of 71 models available in 15 sizes.

The cooling cores, made of aluminum alloy, are produced using vacuum braze welding technology. The suitability of the selected materials together with the repeatability of the production process guarantees the best resistance to the pressures of the different hydraulic circuits, said Oesse.

The high heat exchange efficiency is favored by the combination of internal and external fins to overcome typical clogging issues which would cause a reduction in performance; an additional benefit is less time and cost which occurs with pressure cleaning.

Cooling core and housing are painted with an epoxy powder coating process to protect them against corrosion and increase their durability.

Among the optional additions: brackets with shock absorbers and fixing screws; thermostats available with various settings, threads, and IP ratings; connectors; and splined couplings for hydraulic motors and plugs suitable for closing the unused connectors.

Each product is identified by a unique serial number and by the production batch, ensuring full traceability. A label depicting the specific product configuration chosen by the customer is applied to the sustainable sourcing (FSC) certified packaging.
