  • Large heat of compression dryer
    Large heat of compression dryer is good matching for Centrifugal air compressor, max inlet temperature is 170Deg.C, use that hot inlet compressed air for regeneration. Full system with 200W power consume. Dew-point: -20~-40Deg.C (PDP)
    Pictures is 100Nm3/min KXC-1000 for steel company. With Siemens S7-300 PLC controller and MICHELL dew-point sensor.
  • Compression Dryer
    2012 KL made first set of Zero purge heat of compression dryer with capacity of 120m3/min
    Tech support from Korea, Non air loss, dew-point: -50Deg.C, Testing picture at KL factory:
  • Box dryer
    Most of the mining work is done outdoors, and it is mobile work. Colin developed this box-type dryer, which contains a dryer, oil-water separator and filter, integrated into the factory, which is very convenient for the mining and mining operation group to transport, move and install the production parts.
  • Non-standard compressed air dryer
    We have professional designers specializing in one-to-one design of dryers for special industries line, such as high-pressure dryers, special gas dryers, explosion-proof dryers.
