Desiccant Dryers

HLD Series Twin Tower Desiccant Dryers

BOGE’s HLD Series twin tower desiccant dryers are designed to remove water vapor from your compressed air system. This can lower the pressure dewpoint to -40 or even as low as -94 deg F! No liquid or ice crystals will form even if the compressed air temperature falls to forty degrees below zero. Designed for the most demand applications, BOGE’S HLD Series dryers are your solution for reliable, uninterrupted clean, dry air. The PLC monitors and controls your HLD dryer. The system monitors multiple inputs, showing pertinent data on the digital display and controlling the fully automated drying and regeneration cycles. With the optional Energy Saver Option, your dew point demand system uses a reliable precision hygrometer to monitor the outlet dew point continually and extend the cycle for maximum energy savings. This includes real-time outlet dew point indication and high dew point alarm.

DA Series Compact Desiccant Dryers

Patented Combined Filter & Desiccant Cartridges

 Built-in outlet filtration to eliminate the cost, pressure drop, and maintenance associated with a separate after filter.
 High-density filled desiccant provides maximum adsorption capacity.
 Easy to replace cartridges, simplify maintenance requirements.

PLC Controlled Operation

 The dryer is operated by a robust and reliable PLC control system offering valuable features, including ‘power on, ‘hours run,’ and ‘service required’ indicators.
 Memory retention built into the PLC enables the controller to pick up where it left off in the drying cycle, ensuring consistently clean and dry air downstream.
 Compressor synchronization is a standard energy-saving feature that starts and stops the dryer with a signal from the compressor or point-of-use equipment to eliminate purge loss when drying is not required.

Energy Saving Dew Point Control Option

With this option, a dew point sensor is incorporated into the dryer, providing the ultimate in energy savings

 The outlet dew point is constantly monitored, allowing the cycle time to be adjusted depending on the actual moisture load saving valuable purge air.
 Easily field retrofit; includes dew point display.
 The -ES option reduces valve actuation, increasing service life, and includes an extended 5-year valve warranty.

Floor Or Wall Installation

 can be floor or wall-mounted – simply by rotating the feet 90°.

Optimum Dew Point Performance

 Dryers are provided as standard set for a -40°F dew point. An optional dew point of -94°F is available.
 Air velocity and, therefore, air to the desiccant contact time is carefully controlled via a pressure-maintaining device to ensure optimum dew point performance.

Constant Flow And Pressure

 Pressure is equalized before switching columns to ensure uninterrupted compressed air and consistent air pressure. Equalization also ensures long desiccant life due to minimized desiccant attrition.

Reliable High-Performing Valves

 Integrated check valves and two pilot-operated solenoid valves for proven performance and reliability.
 Pilot-operated solenoid valves.

Maximum Corrosion Protection

 High tensile aluminum columns are alocrom protected and then externally powder coated to provide maximum protection for corrosive environments.
 Provide maximum protection for corrosive environments.
