PH 850-3400 Series Heatless Desiccant Air Dryer

Pneumatech presents the newly designed and significantly improved heatless adsorption dryer range – PH 850-3400. Incorporating high-quality components, PH heatless adsorption dryers provide you with clean, dry air to extend the life of your equipment and products. Heatless adsorption dryers use dry, expanded purge air to remove moisture from the desiccant material.

PH 850-3400 adsorption dryers are capable of drying air to a PDP (pressure dew point) of -40°C/-40°F as standard and -70°C/-94°F as option for higher flows up to 5760 m³/hr/3390 cfm. The desiccant is housed in welded vessels, which are coated and can operate up to 9 barg/130 psig (fatigue load) with std variant and up to 14,5 barg/203 psi with high pressure variant (fatigue load). All dryers can be equipped with 2 coalescing prefilters before and one particulate filter after the dryer (optional).

Thanks to ingeniously designed mechanical components i.e open type of silencers and large vessels, PH 850-3400 range offers highest performance with lowest pressure drop and improved purge loss of 16%.

Considering different needs of the customers, the PH 850-3400 range offers 3 different controller for different requirements. DC 1 Controller version has a basic controller with required controls and monitoring such as service alarm, general alarm relay, synchronization control and optional dew point control whereas Purelogic™ controller version will have the Purelogic™ as central brain of the adsorption dryer. The Purelogic™ optimizes operating costs; ensures maximum reliability by monitoring the most important parameters; and offers impressive control and monitoring capabilities. For special applications where pneumatic control is preferred and no electricity is possible, PH 850-3400 also operates with pneumatically enabled controller.
