Hankison ColdWave™ refrigerated compressed air dryers feature Hankison's most advanced heat exchanger technology.
Being the global leader in compressed air treatment is what continues to set the Hankison brand apart. Since L.E. Hankison patented the Condensifilter™, (forerunner to the refrigerated air dryer) in 1943, Hankison engineers have set the industry standard for refrigerated dryer technology. ColdWave™ heralds the next generation of Hankison high performance refrigerated dryers designed for quality and reliability.

Compressed air demand in most plants fluctuates significantly. Hankison offers compressed air users two refrigerated drying technologies to choose from.
