Overview
Description

Hertz Kompressoren HRD US 500 – 500 CFM Refrigerated Air Dryer – 460V/3Ph

High-Temperature Performance. Integrated Filtration. Reliable Industrial Air Treatment.

The Hertz Kompressoren HRD US 500 is a 500 CFM refrigerated compressed air dryer engineered to remove moisture from industrial compressed air systems while maintaining low pressure loss and efficient operation.

Designed for demanding compressor room conditions, the HRD US 500 can handle compressed air inlet temperatures up to 140°F and ambient temperatures up to 122°F. It cools compressed air to a pressure dew point of approximately +37°F, helping remove condensate before it reaches pneumatic equipment, machinery, plant piping, and downstream processes.

This configuration is supplied for 460V / 3-Phase / 60 Hz electrical service and includes integrated inlet and outlet filtration for a more complete compressed air treatment package.

Key Features & Benefits

500 CFM Rated Capacity

The HRD US 500 is rated for 500 CFM under standard dryer rating conditions.

  • 500 CFM
  • 14.2 m³/min
  • Industrial refrigerated dryer
  • Designed for continuous-duty compressed air systems
  • Low pressure-loss design
  • Compact footprint

+37°F Pressure Dew Point

The HRD refrigerated dryer series is designed to cool compressed air to approximately a +37°F pressure dew point.

Cooling the compressed air causes water vapor to condense so it can be separated and removed before entering the plant air system.

This helps protect:

  • Pneumatic tools
  • CNC machinery
  • Air cylinders
  • Valves
  • Production equipment
  • Compressed air piping
  • Downstream filters
  • General industrial processes

Integrated Pre-Filter & Fine Filter

The HRD US 500 includes integrated inlet and outlet filtration, helping simplify installation and reduce the number of separate compressed air treatment components required.

Pre-Filter

The integrated X pre-filter provides:

  • 1-micron particle removal
  • Oil removal down to 0.5 mg/m³

Fine Filter

The integrated Y fine filter provides:

  • 0.01-micron particle removal
  • Oil removal down to 0.01 mg/m³

The HRD US 500 uses the integrated HGKO1210MX + MY filter package.

High-Temperature Inlet Capability

The HRD US 500 is designed to handle compressed air inlet temperatures up to:

140°F

This makes it well suited for demanding industrial applications and compressor rooms where compressed air temperatures may be elevated.

The dryer is also rated for ambient temperatures up to:

122°F

232 PSI Maximum Working Pressure

The HRD US 500 has a maximum working pressure of:

232 PSI

This provides ample pressure capability for most standard industrial compressed air systems.

460V / 3-Phase / 60 Hz

This product listing is specifically for the:

460V / 3-Phase / 60 Hz configuration

This listing is for the 460V version only.

Digital Controller

The HRD series incorporates a digital controller designed for energy-efficient operation.

Key features include:

  • Digital control
  • Energy-saving operation
  • High-efficiency dryer design
  • Easy system monitoring
  • Low pressure losses
  • Convenient service access
  • Separate electrical and cooling sections

Compact Industrial Design

The HRD US 500 provides 500 CFM of dryer capacity in a compact industrial enclosure.

Dimensions:

  • 29" Length
  • 37" Width
  • 54" Height

Its compact footprint helps make installation easier in compressor rooms where floor space is limited.

R-134a Refrigerant

The HRD US 500 uses R-134a refrigerant.

The refrigeration system is designed to cool the compressed air stream, condense moisture, and provide reliable moisture removal under the specified operating conditions.

Ideal Applications

The Hertz HRD US 500 is well suited for:

  • Manufacturing facilities
  • CNC machining operations
  • Metal fabrication
  • Automotive manufacturing
  • Plastics manufacturing
  • Woodworking operations
  • Packaging facilities
  • Pneumatic automation
  • Industrial maintenance departments
  • General manufacturing
  • Larger rotary screw compressor systems
  • Compressed air systems requiring approximately 500 CFM of dryer capacity

Proper Dryer Sizing

Refrigerated air dryers should be sized according to the actual operating conditions, not compressor CFM alone.

Dryer capacity can be affected by:

  • Compressed air inlet temperature
  • Operating pressure
  • Ambient temperature
  • Compressor airflow

High inlet temperatures and high ambient temperatures can reduce the effective capacity of a refrigerated air dryer, so proper sizing is important.

If you are unsure whether the HRD US 500 is the correct size for your application, contact Compressed Air Advisors and we can help calculate the proper dryer size based on your actual operating conditions.

Why Choose the Hertz HRD US 500?
