To remain competitive, manufacturers are challenged to find new and more efficient methods to increase productivity. Clean, dry compressed air improves equipment performance, reduces unscheduled downtime and lowers maintenance costs.
HPRp series is third party performance certified, ensuring optimal compressed air system protection.
|
|
|
|
The International Organization for Standardization (ISO), the world's most recognized developer and publisher of international standards, identified three critical forms of contamination as common in compressed air systems - Particulate, Water and Oil. ISO Standard 8573-1: 2010 categorizes each contaminant and assigns a quality class, ranging from Class 0, the highest purity level, to Class 9, the most relaxed. This enables end-users of compressed air treatment equipment to select an air quality level meeting the requirements of the application.
The HPRp Series effectively removes all three contaminants in a single air treatment system.

|
- As standard, all dryers are equipped with filter/separator elements, delivering:
- ISO Quality Class 3: Particulate removal
- ISO Quality Class 4 - 5: Pressure dew point
- ISO Quality Class 4: Remaining oil concentration
- Optional high efficiency coalescing filter elements deliver:
- ISO Quality Class 1: Particulate removal
- ISO Quality Class 4 - 5: Pressure dew point
- ISO Quality Class 1: Remaining oil concentration
Liquid oil and hydrocarbon vapor removal is more effective at lower temperatures. Cooling the air to 40ºF/4ºC allows some of the oil vapor to condense into a liquid, improving filtration efficiency. The oil content exiting a refrigerated air dryer equipped with integral coalescing filtration is 20-25 % lower than a stand-alone filter installed in the system.
The annual purchase of a maintenance kit provides a lifetime of ISO Quality Class Air.

Advanced Cabinet Design
|
|
- Unique cabinet construction enables 360-degree access to critical components.
- Convenient panel removal provides trouble-free entry for routine maintenance.
- Baked polyester, powder coated cabinets withstand harsh environments, maintains long-term visual appeal
- HPRp100 - HPRp750: Utility connections for inlet and outlet air, incoming power and condensate drains are positioned on the right side panel.

|
|
|
Time Proven Reliability
|
|
- Durable, hermetically sealed refrigerant compressors provide a practical and safe solution without compromising energy efficiency.
- Dryers utilize environmentally friendly R134A and R404A refrigerants, recognized globally as efficient and safe HFC solutions.
|
|
|
|
Corrosion Resistant Heat Exchangers
|
|
- Compressed air is chilled to the specified pressure dew point in stainless steel brazed plate heat exchangers, offering corrosion resistance for the life of the dryer.
- Stainless steel plates are press formed with chevron patterns, creating highly turbulent flow, providing a self-cleaning effect.
- Smooth, non-fouling stainless steel surfaces promote low resistance to flow, improving system efficiency.
- Heat exchangers are fully encapsulated in non-degrading insulation to maintain thermal efficiency.
