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.

REFRIGERANT CIRCUIT- HRD HPN

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

THE SEPARATOR EFFICIENCY- HRD HPN

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

HEAT EXCHANGER

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
transfer.

SCROLL COMPRESSOR

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