    The premium high-flow adsorption dryer

    The Pneumatech PB 760-7400 HE delivers a low PDP of -40°C/-40°F as standard (-70°C/-94°F optional) with minimal operational costs. The range comes in a blower purge and two zero purge variants (with open and closed loop cooling), each offering flows up to 12,600 m3/hr. 

    The PB 760-7400 HE is built for premium high-flow performance:

    • High-quality, high-efficiency desiccant with a long lifecycle
    • Minimal risk of crushed desiccant thanks to the sonic nozzle and large welded vessels
    • Very low internal pressure drop (0.2 bar/0.9 psi)
    • Highly efficient counter-current regeneration
    • Smart Cycle Control algorithm delivers energy savings at partial load
    • The electric heater’s design and stainless-steel, insulated build ensure optimal flow, energy efficiency and a long lifetime
    • Galvanized pipes with flanged connections simplify maintenance and minimize the risk of leakage
    • Compact base frame with forklift slots saves on floor space
    • Optimal control and monitoring thanks to PurelogicTM Controller 

    Blower purge and zero purge adsorption dryers – how do they work?

    Adsorption dryers remove moisture from compressed air by passing it through one of two towers filled with desiccant. When the desiccant in one tower is saturated, PB HE dryers use heated blower purge air to remove the moisture from the adsorbent material (while the other tower handles the drying). That means they have no purge loss during regeneration. The zero purge variants reduce lifecycle costs even further by also eliminating purge loss during cooling.

    Adsorption Dryers

    Adsorption or desiccant dryers remove moisture from air or gas streams by passing them through a porous material called a desiccant, ensuring dry and moisture-free conditions.
