Radiator type heat exchangers (plate and fin type) use fans to circulate air and cool the fluid inside the tubes of the exchanger.
Since the cooling medium is air, these exchangers can be used without restriction.
No water is used in the cooling process, so there is no need for plumbing. This also means that there is no danger of the fluid in the tubes being mixed with water.
The device has very few component parts, and this makes maintenance very easy.
The fans used have very low operating noise.
The radiator is made from aluminium alloy, making it light and compact.
And, the use of a standardized frame means it can be used with a variety of standards of motors.
