Don Cormack, Adrad Chief Executive Officer

On Highway applications such as heavy transport, buses and mobile cranes are remarkably demanding on engine cooling systems – high duty cycle, high temperature operating environment, excessive vibration and thermal shock (fan off-cycling, turbo cycling) are par for the course.

Air Radiators develops innovative, custom, cost-effective cooling solutions for:

Engine circuits
Air conditioning
Transmission oil, power steering and fuel cooling

Our solutions are durability tested to OEM specifications and feature long-lasting technologies with proven strength, ease of installation and low maintenance.

The challenges of higher heat rejection levels, demand for increased engine power, lower noise levels, fuel savings, reduced weight and space restrictions call for unique solutions. At Air Radiators, we use highly refined design tools and vast experience to develop solutions across a broad design scope including:

Engine jacket water
Charged air-to-air cooling
Fuel cooling
Fan cowling
Fan, belts and core guarding
Plumbing kits
Deaeration system - external and integral
Fan impeller and fan pulley spacer

We can provide individual components or a completely “dressed” assembly package to meet your specifications and allow modular fitment to the vehicle with no additional work. Our commitment is to deliver a cooling package that represents the best value for your investment.


Air Radiators develops innovative heat transfer solutions for On Highway applications using an extensive range of tested and proven products including:

Our cores are constructed using UltraFused header joint technology. Options include plate fin and CT type in copper or solder coated
Aluminium cores to lower cooling system weight
Charge Air Coolers featuring Ultra Seal technology
Pin Fin technology for auxiliary cooling
AC condensers
Recirculation seals
Fans and fan shrouds
Reserve tank

Using a modular design platform and our engineering prowess, we integrate these products into packaged cooling systems or individual components with a high degree of customization for all mobile applications.
