EMMEGI air-oil heat exchangers are used for cooling
oil hydraulic systems using as the coolant ambient air
that passes over the radiant by means of a fan
operated by an electric or hydraulic motor.
The cooler element, in high resistance aluminium alloy,
is obtained by means of a braze-welding process
carried out under vacuum.
The particular configuration of the cooling pipes
increase the turbulence of the fluid consequently of the
exchange capacity; moreover, the presence of special
jets on the cooler finning further improves the total
The result is a very small, light and robust
technologically advanced product.
The air-oil heat-exchangers DRAIN Series were born
to answer the large application needs of the market.
The main characteristic of this heat exchanger is
the high efficiency with low oil flows.

Technical specification of Cooler
. Material: “long life” aluminium.
. Operating pressure: 20 bar
. Test pressure: 35 bar.
. Max operating temperature: 120°c.
. For specially “ aggressive” atmospheres contact
The exchangers can be fitted in a horizontal position,
respecting the minimum distance from the wall (see
fig.1) so as to ensure a natural flow of cooling air.
The exchangers is usually installed on oil tank return
piping; it must also be protected from impacts and
mechanical vibrations by supports and must be
connected to the plant with flexible pipes.
Avoid subjecting the exchanger to sudden changes in
flow, hammering and pulsations that can cause
irreversible damage to the element.
