NRD-HP Series
Desiccant Compressed Air Dryers
The Pure-Stream NRD-HP( 652 PSIG) is designed and manufactured for high-pressure applications that require high-efficiency dry air. Its unique mono-block stainless steel heat exchanger protects against corrosive elements and allows for efficient heat transfer. The NRD-HT series high pressure refrigerated air dryers are available as a standard line up to 652 PSIG. The dryer line is a perfect solution for refrigerated air dryers applying in PET blow molding, pharmaceutical, injection molding, and other applications that require high-pressure compressed air.
The Pure-Stream NRD-HP( 800+ PSIG) is constructed with the application in mind and is engineered as a custom-built-to-order dryer. These units are designed to the specification of the application they are being used for, to ensure the absolute parameters of the application are met.

Principle of Operation
- Saturated , compressed air is cooled in the air-to-air heat exchanger.
- The pre-cooled air passes through the evaporator where it is cooled to required temperature.
- The Condensate, separated from the compressed air in the demister, is discharged automatically by the condensate drain.
Overview
Next Air & Gas Performance Advantages
The performance of any desiccant dryer depends on the quality of its key components. Next Air & Gas uses the best available valves, controllers and desiccant. With accurately designed and sized components, the dryers are manufactured to provide you with years of trouble-free operation.
Vertical Heat Exchanger Design
The patented aluminum heat exchanger has been designed to offer the maximum performance and minimum pressure drop. The unique heat exchanger is both an air-to-air heat exchanger as well as an air to refrigeration heat exchanger. The warm and humid air is pre-cooled by the cool dry air that is leaving the dryer, which increases efficiency.
Digital Controller
All models have a digital control board, with a double sensor system that keeps the dew point and condensing pressure within ideal operating parameters.
Condenser Cooling | Coils
Generous sizing of the condenser unit ensures maximum performance of the refrigerant circuit and the ability to operate with changes in ambient conditions quickly. Access to the condenser for cleaning and maintenance is simple.
Refrigeration Compressor
The circulation of the refrigerant in the cooling system is done through the highly efficient refrigerant compressor. Thanks to its innovative construction, this has reduced energy consumption and increased reliability levels.
Condensate Drain Controls
NCE dryers are equipped with an electronic drain valve which is controlled by the programmable controller. The complex digital controller ensures timely draining of the condensation, but also allows for easy programming and testing of the drain valve
