Profile: Applied Cooling Technology LLC specializes in the design & manufacture of shell & tube and finned air blast heat exchangers and associated technologies. We cater to various industries, like the rail locomotive, marine, petrochem, industrial and aerospace sectors. We are accredited with ISO 9001:2000 quality systems. Finished heat exchangers are inspected and pressure tested. Common methods for pressure testing include hydrostatic (using either mains or demineralised water) and pneumatic (using compressed air or other gasses such as nitrogen). Individual tubes can also be pressure or non-destructively tested prior to use. Dri-Seal special products have been developed to extend the life of shell & tube and air-blast heat exchangers.
