AIR-OIL HEAT EXCHANGERS WITH ALTERNATING CURRENT ELECTRIC FANS - SERIE AP:
Today the use of air in hydraulic equipment is more and more common.
The benefits are: No water supply required Totally independent of plummed systems Reduced running costs in comparison with the water-oil exchangers, even if initial investment is higher
Residual warm air can be used for heating
With air-oil heat exchangers the radiator unit is of aluminium for minimum conduction.

HA Serie:
Standard air-oil combined two-circuit heat exchangers used for cooling compressors from 7.5 to 160 kW. Radiator in aluminium alloy, vacuum braze welded, with high-efficiency turbulators on the air side. Power supply of fan only in AC, blowing ventilation.

SELF-CONTAINED COOLING UNITS:
The RAS cooling units were engineered and manufactured to substitute the former GAR and OCS series with an uncomplicated and compact product. The units are made up of an aluminium air-oil exchanger and a single electric motor which operates both the oil circulation gear pump and the cooling fan.

DIRECT CURRENT AIR-OIL HEAT EXCHANGERS:
This series of heat exchangers is particularly useful in cooling oleo-hydraulic plant on mobile machinery as it is fitted with direct current 12 or 24 V electric fans. The cooling element is in aluminium, a material of high thermal conductivity, which provides high thermal yield from relatively contained dimensions. The particular conformation of the radiant block is such that APL series heat exchangers are highly resistant to the stress produced by hammering which, however, at peak value, should not exceed the maximum dynamic pressure of 20 bar. The maximum permitted static pressure is 35 bar.

|
HM Serie:
Air-oil heat exchanger with tank and filter, used for the cooling of hydrostatic transmissions, especially on cement trucks and concrete machines. Power supply voltage of intake fan exclusively 24 V DC.

|
AIR-OIL HEAT EXCHANGERS -SERIES AP WITH HYDRAULIC MOTOR :
This type of exchanger has been designed for use on movable machines where battery feed is insufficient or when exchangers with direct current supply are inadequate to produce high thermic yields. The radiative unit is of aluminium because this material is a very good conductor; providing high thermic yields and relatively compact over-all dimensions. Thanks to the particular construction of the radiative unit the exchangers of the series APL cope well with water hammer conditions which, at peak values, must not exceed the minimum allowable dynamic pressure of 20 bar. The maximum allowable static pressure is of 35 bar.
