Clean and Dry Compressed Air

Compressed air is an important source of energy. The need for an air supply to be clean and contaminant free is crucial. So too is the need for dry air without traces of water or oil vapor. Any form of moisture in a compressed air line has the potential to cause costly downtime, machine damage and product spoilage.

Energy Efficiency

A compressed air system is one of the most important determinants of overall system efficiency and represents one of the largest opportunities for energy savings on any site. There can also be significant cost benefits of an efficiently designed and maintained compressed air system.

General Air Products’ line of heatless desiccant compressed air dryers offers a multitude of additional energy saving features, which allows the dryer to be linked with a compressor control system and reduces air consumption during periods of low demand.

The HDD Series from General Air Products

With flow rates from 4 scfm to 365 scfm the entire range can operate at -40oF pressure dewpoint as standard, with an option of -100oF for more critical applications. The range has been designed and engineered to meet the air purity class in accordance with ISO 8753:1-2001 (E).

The units have an intelligent diagnostic system installed as standard on each model. Ease of service has been foremost in the design. Each unit can be serviced without disturbing the surrounding pipework. Desiccant cartridges can also be changed out effectively without causing excessive down time.

The compact size of General’s heatless desiccant compressed air dryers ensures that installation is simple and versatile. The units can be installed in small spaces in either a vertical or horizontal position. Models HDD 004 through HDD035 can also be floor or wall mounted. Models HDD004 to HDD035 have multiple porting options, with a total of six inlet / outlet connections and many pipework possibilities.

Removable front panel for easy service access. Standard controller incorporates an optional energy management system. Simple purge plug change-out, no need to dismantle units. Spring loaded desiccant cartridges to avoid desiccant attrition. Clear cartridges designed to enable visible inspection of desiccant condition. Internal Silencer to reduce noise levels and ensure smooth chamber depressurization Suitable for wall mounting (models HDD004 - HDD035) and horizontal integration (all models) Benefits: General Air Products HDD Series heatless desiccant compressed air dryers provide a host of financial benefits such as an integral electronic drain and service interval indication, all of which are included in the standard dryer package. With XA grade 0.01 micron oil removal filtration (standard on models HDD004 - HDD035), an integral 1 micron dust filter and a choice of -40oF or -100oF pressure dewpoints, the HDD Series meets and exceeds the highest standards of purity as specified in ISO 8573:1-2001 General's HDD Series dryers offer a multitude of additional energy saving features, which allow the dryers to be linked with a compressor control system and reduces air consumption during periods of low demand. Condensate management is essential to maximize dryer efficiency. Every HDD Series dryer is supplied with an integral electronic drain valve which is operated and controlled by the CPU. This drain valve opens at the end of every cycle when an indicator illuminates and the CPU checks for any sign of malfunction in the dryer. Operation of the unit is viewed by the diagnostic control panel located on the front of each unit. An improved desiccant cartridge design with integral handle facilitates a simple and clean change out procedure.
