Products and Services:

Jacket Water Radiators
Thornhill have been at the forefront of new radiator development since the company formed.  Finless products are widely used in a number of fleets.  In collaboration with our suppliers, NRF Radiator we are introducing ‘hemmed fin’ technology. Hemmed fin radiators have been developed by NRF for many years and offer superior strength and ease of cleaning over currently available cores.

Oil Coolers
Shell&tube and air blast oil coolers can be serviced or replaced.  We also over conversions of fixed to floating stack coolers which enhances product life and increases serviceability.

Charge Air Coolers
As a result of our long history of design and development we have a deep understanding of rail charge air coolers.  Out products have many hours of reliable service in many fleets. We can now offer charge air coolers with ‘hemmed fin’ technology.

Cooler Groups
Customers are increasingly keen to reduce their supply chains, to improve efficiency.  Thornhill Rail can undertake a greater range of cooler group services than simply refurbishing radiators.  We have extensive experience with full NDT of frames, fan replacement and hydraulic system overhaul.
