Deltech AP Series Blower Purge Desiccant Dryers

Air Technologies^® is a proud distributor of Deltech® AP Series blower purge desiccant dryers

The Deltech AP Series desiccant dryers are designed for plant and instrument air applications where low dew points are required. The AP Series dryer operates on a standard 8 hour fully automatic NEMA Cycle. During this continuous process, one tower is drying the incoming wet air for 4 hours. During the same time period the other tower is being reactivated with heated atmospheric air. The heating of the atmospheric air is external to the tower and is controlled by a thermocouple at the heater outlet. No internal or embedded heaters are used. No cooling water or process purge air is required.

The Deltech AP Series dryer also incorporates an energy saving control system that senses the temperature of the regeneration air as it exits the tower and terminates heating at a preset condition, thus optimizing energy usage.

Featured Components

Valves - Butterfly valves are utilized to control the flow of air through the towers. Inlet and purge exhaust valves are cast iron bodies with stainless steel internals that provide good wear resistance, and minimize maintenance.

Heater - The AP Series dryer is designed to use a low watt density heater with optimal surface area. Low watt density heaters mean lower heater sheath temperatures and extended heater life. Extended surface areas result in the most efficient heat transfer.

Blower - A positive displacement blower provides the regeneration purge for the system. This blower has the major advantage of providing a constant volume of purge air over a wide range of pressures. The positive displacement blower delivers a precise flow rate regardless of varying system pressure drop while using only the horsepower required to do so.

Safety features - Low wattage heater tubes, high temperature protection, thermostatically controlled heater core, control power transformer
