HDR Series
Desiccant Compressed Air Dryers
Next Air’s HDR Rental Heatless Series dryers are engineered for exceptional durability and mobility no matter the application, to provide temporary and reliable dry air under harsh conditions in any environment .
With global standardization and rental applications in mind, Next’s HDR series dryers have incorporated standard design features, that are often considered option adders. The HDR comes standard with mounted pre & post-filtration and stainless steel control air tubing.
The design pressure of its pressure vessels is rated at (200 psig / 13.7 bar) with the industry standard being (150 psig /10.3 bar ). In addition, Next’s pressure vessels on models (600-1,600cfm) are partnered with an ASME VIII coded and CRN Certification. The UL and CUL-certified electrical panel is protected by a Nema 4x Stainless steel electrical enclosure. The HDR series is also accompanied by a rugged draggle skid packaged within a 3-sided caged enclosure. The HDR series dryer Next’s comprehensive option adders allow the dryer to meet any application it is dealt with. Offering dewpoint readings of-40 °F/ °C to-100 °F/-73.3°C
