Walker Filtration Pro Dry

Walker Filtration’s range of PRODRY desiccant dryers deliver optimum performance and provide a compressed air drying solution you can count on. With built in energy saving features across the range, the PRODRY series of heatless regenerative dryers has been designed to incorporate an energy management system which allows the dryers to be linked with a compressor control system to reduce air consumption during periods of low demand – greatly reducing energy consumption and improving energy efficiency.

Optional Dewpoint Management Control, flexible installation and improved serviceability are central, as downtime associated with servicing and installation not only effects productivity but also directly impacts upon costs.
Constructed using extruded aluminium towers which are fully anodised for corrosion protection, this range of high efficiency dryers has been designed and tested to meet the purity classes specified by ISO 8573-1: 2010.

All dryers are built to be fully compliant with international standards and have multiple voltage options, suitable for worldwide installation.

The PRODRY range of desiccant dryers, with 17 models, provides flow rates from 4 to 360 scfm (7 to 612 Nm./hr). This modular series offers a robust and reliable compressed air drying solution.

Designed to suit various applications, the PRODRY range consists of low flow models PD004 – PD035, and larger flow models PD0046 – PD0360. Delivers a compact solution to moisture removal from compressed air.

• Ease of service – desiccant columns are easily removed, allowing access to desiccant cartridges for quick and efficient change out.
• The PD004 – PD035 design incorporates highly reliable 12 VDC solenoid control valves which operate diaphragm exhaust valves. The control valves are set to be ‘normally closed’, a fail safe that ensures that the dryer will still provide compressed air – even in the event of a power failure.
• Energy Efficient Design – LED Controller (supplied as standard). The compressor can be linked to the energy management contacts, isolating the purge flow during periods of low demand for efficient use of compressed air. Provides continuous updates on dryer performance via an intelligent built-in central processing unit (CPU). The LED Controller illuminates to alert in the event of low power faults, controller faults, drain valve faults, solenoid failures and when service intervals have been reached. An external alarm process is built-in offering total security and peace of mind.
• Integral electronic drain, service interval indication and integrated condensate management are included in the standard dryer package.
• Unique multiple inlet and outlet ports enabling both left-hand and right-hand compressed air supply and greater installation flexibility.
• Quiet Operation – silencer to reduce noise levels to below 85 dBA.
• Desiccant Cartridge design includes an internal filtration and controlled desiccant bed geometry ensuring consistant dewpoint performance and simple maintenance.
• Integrated Condensate Management Essential to maximising dryer efficiency, condensate management features are supplied as standard with all PD004 to PD035 Units. Units are supplied with an integral 12VDC solenoid drain valve which is controlled and operated by the CPU. Two external push-in fittings are provided on the rear panel which can be connected to the drain port of the pre-filter(s).
