Profile: ATKM LIMITED LIABILITY COMPANY is engaged in designing, manufacturing, selling & installing ventilation fans and evaporative cooling ventilation systems. Our products include exhaust fans and industrial fans. Our evaporative cooling ventilation system can be used in injection molding factories, rubber factories, silk-screen factories, electron factories, printing factories, foodstuff machining factories, weave factories & blanch & dye workshops and washhouses. Our evaporative cooling ventilation system is a form of negative pressure ventilation in which exhaust fans are installed at the end of a building and large cooling pad (filter pad) are installed at opposite end of the building, so the ventilation air travels the length of the building. This results in a relatively high average air velocity, which produces a continuously large amount of fresh & cool air while decreases exhaust odorous, dusty, muddy and stuffy air.
