Two-pass cooling system. Using a
two-pass system, the AMOCS radiator
provides a more efficient heat exchange.
The coolant is routed from a sectioned
bottom tank up the front side, over the
top of the core, and down the engine
side of the core to the bottom tank.
This flow pattern allows the coolant
to pass through the radiator twice
for better cooling. Modular Design. The cooling elements
are individual core modules connected
to a sectioned bottom tank. There is
no top tank to remove.
• Standard 9.4 steel fins per 2.54 cm
(1 in), or an optional 6 steel fins per
2.54 cm (1 in)
• Brass tube construction within each
core for improved reliability
Hydraulically Variable, Demand Fan.
The hydraulically driven demand fan
provides engine cooling capability that
is matched to the ambient conditions.
In cooler conditions, the fan turns at a
slower speed, reducing power demands.
This frees up more power in high load
factor operations or reduces fuel
consumption in lower load factor
operations. Low speed fan operation
also reduces both operator and spectator
sound levels. The ADEM A4 engine
controller regulates the fan speed
through a variable displacement pump.
An attachment low speed option is
available for cold weather operations
to avoid over cooling the engine.
Easy Serviceability.
• Servicing of the AMOCS can
be performed without tilting the
radiator guard
• No need to remove or replace a
major component as on single-core
radiators
• Each core module can be replaced
individually (without removing the
entire radiator), saving considerable
cost and repair time
