Refrigerated Air Dryer

SPX brand is pleased to introduce the new HES Series high capacity refrigerated air dryer and HCD Series heat of compression desiccant air dryer. The HES series was specifically designed for large flow capacity applications ranging 3750 to 10,000 scfm (6371-16,990 nm3h).  

Utilizing the latest technological advancements, the HES series delivers load matching performance by precisely matching input power to real time demand. Innovative modular construction employs independent air treatment modules for flexible arrangement, ease of installation and service.  Dimensionally standardized modules may be efficiently combined to form larger combinations, quickly adapting to changing customer demand.  Redundancy in critical components offers fault-tolerant operation, delivering optimal system reliability.  Multi-station redundancy provides alternative drying capability in the presence of component failure. 

Systems may be operated with an additional module to gain benefit of lower pressure drop and back-up redundancy, without compromising power consumption. The HCD series heat of compression desiccant air dryer, flows 350-10,000 scfm (595-16,990 nm3/h) reduce energy costs while delivering instrument quality compressed air.  Ideally suited for oil-free air compressors, “waste heat” generated during the air compression process is effectively utilized to regenerate of the off-line desiccant tower. Energy efficient design consumes less than 100 watts per year, approximately the energy utilized by a desk-top computer.  No purge air is required for regeneration, delivering the lowest operating cost of all desiccant dryer designs. Reduced maintenance- no blower or heaters- provides trouble fee operation.
