If a material is to be cooled rapidily – as by quench cooling – intimate contact with the coolant is essential. Quench cooling of surfaces above 100ºC in ambients at atmospheric pressure calls for the use of water jets, air knives or the use of synthetic heat transfer fluids. Waterjet quench cooling allows the momentum of high velocity droplets to carry them against the surface – if only momentarily – so avoiding the vapour blanketing that would be present across an otherwise static boundary layer. Should water-marking be an issue (as for aluminium extrusion), it may be obviated by quench cooling with demineralized water.

The effective design of process cooling systems calls for proper study of the host application. If a product is to be cooled, then not only should its thermal and physical properties be known, but also the way it responds to change (for example, a non-Newtonian stream being tempered or a metal being quenched).

Whilst computer applications make easy meat of describing sytem behaviour, one should retain control of the basic model, and not dote on the hidden routines and elements nested inside bought-in software. In our view, there is always much to be said for pencil-and-paper, and we retain the total capability to design & build the machinery, plant and equipment for all types of process cooling systems from scratch.

The better a cooling process is designed, the less need there will be for automated control devices. A well-bred system reacts organically to imposed loading, and might need no more than (say) a fan drive inverter or temperature switch to modulate its response. Even when the maths and physics behind operations might entail some effort, efficiently designed process cooling systems should be elegant in the simplicity of their behaviour and construction
