Fleet Sheet www.hbsna.com Multi-treatment cartridge employs five stage cleaning to ensure dry system air. Integrated 3-bolt SAE mounting bracket allows for easy installation in OEM and existing applications. Extra compact size of less than 11 in. tall (even with integrated muffler) allows for easy installation anywhere. Integrated governor improves air dryers performance and reduces application costs by eliminating existing governor and related piping. Integrated heater prevents moisture from freezing and damaging the dryer. Integrated turbo protection valve reduces engine horsepower loss and improves fuel efficiency. Integrated regeneration valve for system air desiccant regeneration ensures that sufficient system air is available. Metri-pack heater connection allows for easy installation. Integrated muffler allows for superior quiet operation. Haldex DRYest Air Dryer Special Notes: Application Information Purge air is used to back flush the dryers desiccant thereby removing moisture and contaminants. Purge air is stored internally on some dryers such as the PURest, while most others use air stored in the vehicles wet tank or in a separate purge tank. 1. Determine governor type: internal or external (D2 Style). 2. Determine if purge air supply will be from vehicle air brake system (regeneration valve style --- similar to Bendix ADSP, Wabco and C/R) or from separate, remote mounted, purge tank. 3. Ideal for vehicles with normal or high air consumption rates. In high consumption applications use with external purge tank. ✓ Competitive Advantages Five-stage drying process Advantage Haldex: Removes up to 99% of contaminants in the compressed air system and eliminates oil while maintaining high water absorption capability. water drying capacity doesnt impede airflow ✓ Exceptional Advantage Haldex: And reduces chances of corrosion and freezing problems. desiccant service life means ✓ Extended Advantage Haldex: Fewer replacements and reduced maintenance over the life of the vehicle. slide in-and-out cartridge ✓ Four-bolt Advantage Haldex: Provides for quick replacement of the dryer cartridge while on the vehicle ---with no hard to remove spin-on cartridges with seized threads. turbo protection ✓ Integrated Advantage Haldex: Reduces engine horsepower loss and improves fuel efficiency. regeneration valve ✓ Integrated Advantage Haldex: Ensures sufficient system air is available. muffler ✓ Integrated Advantage Haldex: Allows for superior quiet operation. volume capacity ✓ High airAdvantage Haldex: Treats up to 30 SCFM. heater ✓ Built-inAdvantage Haldex: Prevents moisture from freezing and damaging the air dryer, available in 12 and 24 volt. size ✓ Compact Advantage Haldex: Provides easier installation into limited spaces. assembly weight ✓ LighterAdvantage Haldex: Only 14 lbs. means theres more payload capacity. vehicles with high air consumption ✓ Ideal forAdvantage Haldex: Including applications such as mixers, transit, coaches, dumps and refuse. 11/02 5M CUT L20401 Fleet Sheet www.hbsna.com Haldex DRYest Air Dryer Cross-Reference Information The Haldex DRYest is a drop-in retrofit for these Air Dryers: ❖ Wabco SS Series ❖ Bendix ADSP The Haldex DRYest will retrofit these Air Dryers if an auxiliary purge tank is added: ❖ Bendix AD2, AD4, AD9, ADIP ❖ C/R Brakemaster Related Items Checklist ◆ External Purge Tank ◆ Compressor Discharge Hose ◆ Brass Fittings ◆ Spare MTC Cartridge ◆ Nylon Air Brake Hose ◆ Air Governor System Regeneration with External Governor Governor Primary Competitor Overview 1) Bendix AD2, AD4 and C/R Brakemaster a) No turbo boost pressure loss protection. b) Utilizes only one desiccant type for removal of water and contaminants. c) Difficult to service, usually must remove from vehicle which can take up to 45 minutes. d) Heavier/Taller/Wider than the DRYest. e) Separate purge tank is required for the C/R T2000, T3000 and HD2000. 2) Bendix AD9 a) Utilizes only one desiccant type for removal of water and contaminants. b) Difficult to service, usually must remove from vehicle which can take up to 45 minutes. c) Heavier/Taller/Wider than the DRYest. d) Utilizes multiple mounting brackets and bolts. 3) Bendix ADIP a) Single bolt cartridge susceptible to seized threads. b) Utilizes only one desiccant type for removal of water and contaminants. c) Expensive desiccant service. d) Heavier/Taller/Wider than the DRYest. e) Higher internal resistance to air flow. 4) Bendix ADSP/Wabco SS System Purge a) Utilizes only one desiccant type for removal of water and contaminants. b) Spin-on filters are often difficult to remove due to seized threads. c) Maximum SCFM ratings for Bendix and Wabco 1000 and 1200 dryers is 25 SCFM -- Cannot be used on high volume applications. d) Higher internal resistance to air flow.
