HRD HPN Series

This design achieves a hyper-efficient 100 % contact between the air and refrigerant circuits, delivering state-of-the-art performance and great cooling efficiency.

The state-of-the-art 3-in-1 design features very low differential pressure delivering significant energy savings. The 3-in-1 Heat-Exchanger is compactand allows the dryer to be smaller and reduces the space required for the dryer. Hertz offers a variety of 3-in-1 dryers equipped with the 3-in-1 Heat-Exchanger to meet a full range of capacity and power requirements.

  • Two valve regulation system (thermal and bypass), allowing to fill properly the exchanger and giving a max. temperature to the exchanger
  • High quality security test of potential leakage
  • Use of hermetic compressor as standard
  • High quality, long lasting components
  • Quick start and reaction time


  • Double centrifugation due to the bottom fin
  • Reserved direction for the compressed air
  • Gravity effect to the condensed water
  • Special anti-return system
  • Integrated separator


Hertz HRD HPN range High Pressure Air Dryer Series have stainless steel brazed plate heat exchanger. It is designed for high pressure air
dryers. The heat exchanger has the following sections in one module;

  • Air/Air heat exchanger (Economizer)
  • Air/Refrigerant heat exchanger (Evaporator)
  • Water separator

With reliable stainless steel and optimized design, Hertz HRD HPN heat exchangers supply size reduction, anti corrosion and great heat


  • Better coefficient of power
  • Less energy consumption
  • Higher resistance to liquid shocks
