Oil / Air Cooling Units, OKAN Series
A wide range of standard units can now meet most of the applications in the field of oil/air cooling units. 16 sizes
of the OKAN series are available with a heat dissipation of max. 2.5 kW/K, subject to market requirements, in
one- or multi-pass design. Furthermore, for plant engineering and for series producers we are developing
project related special designs.
Basic element is an aluminium cooler core. Oil tubes are fitted with a turbulence element to ensure an optimum
heat transfer. To achieve high cooler capacity the fin arrangement, fan blades and power of engine are
harmonised aerodynamically and thermally.
OKAN II
Frame design for all common applications
OKAN III
65 mm core depth, specially for mobile hydraurics
Applications
Operating data
• Cooling of oils, hydraulic fluids and emulsions
using ambient air - especially in the field of
mechanical engineering, plant engineering,
building machinery and the special vehicle
industry.
• Used as additional cooler at peak load range
(summer)
• Where water is not available or piping is too
expensive
• max. cooling capacity: approx.100kW resp. 2.5
kW/K
• max. operating temperatures: for oil 120°C, for
emulsion 90°C
• max. operating pressures: 16 bar
• ambient temperatures: -20°C up to +40°C
• frontal areas: 0.05 up to 1.00m2
• fan drives:
three-phase motor
DC motor
hydraulic motor
