3ACX air-cooler
3.1 Description
An ACX air-cooler is used when a suitable cooling-water supply is not available for the pump or for a mobile pumping
system. The ACX air-cooler is an enclosed electric fan and fixing bracket assembly which is easily fitted to bolt holes
in the base of the pump. The ACX air-cooler has a 24 V d.c. motor which can be powered from a rear panel socket
on the EXC Controller, an EXT DX podule, a TIC, or any suitable electrical supply.
All air-coolers are supplied with side-mounting brackets. The ACX250 is also supplied with an axial-mounting bracket
for optional use with EXT250M pumps only.
The ACX400 air-coolers are available for both axial and radial mounting. It is possible to use both variants
simultaneously if so desired and space allows. TICs can provide power for one fan only.
Refer to the EXT pump instruction manual to check the suitability of air cooling in your particular application.
