Additional Options to the General Options List

Model options with Tank, without Tank, with tank&dryer (HVD 5-15)

Electronic Control

Hertz Kompressoren rotary screw compressors are equipped with easy-to-use, robust and long-lasting microprocessor controllers with communication capabilities as per the product line to ensure smooth operation and uninterrupted production.

Screw Block

Patented and durable screw block that provides high-capacity of air, and that is specially selected for each model's capacity requirement
Production of air with less loss of air, thanks to the new rotor profiles, and lower torque requirements
New generation bearing design with increased load carrying capabilities

Air Oil Separator

Easy-to-detach spin-on type separator

(HVD 5-15)

High-efficiency immersion type separator

with long service life (HVD 18-300)

High performance separation with

three-stage design

More efficient separation at lower

volume with deeply wrapped,

intertwined separation layers

Low amount of oil mist in outlet

air ≤ 3 ppm

Main Motor and Drive System

Premium 230-460 /3 phase/60Hz, IE3 IP55 electric motors with F Class insulation, Wye-Delta motor starting system. Long-lasting and efficient transfer system thanks to use of elastic couplings on direct coupled models.
